Finally getting my car back together after the florida hurricane fiasco and want to go megasquirt. I was thinking of using a megasquirt to control an 8 injector setup even though it may sound ridiculous. However, I would like to know if I can use a megasquit with just 4 injectors and tune the car to drive like stock before I put the turbo on. I want to do this so I can prove the car will drive like it's using the stock ECU for fuel control.

Most piggyback ECU or full stand-alone fuel electronics result in a car that hesitates, bucks or bitches about everything other that WOT. I have witnessed several of these. But since the megasquirt is only changing the fuel and spark maps, can the EGR system, EVAP system, 32 MPG highway driving and civilized daily driver drivability be retained? Like no one could tell you had a megasquirt.

I am willing to learn to tune and can program a MC68HC05 in assembly for other projects. I understand how these micro-controllers work. I just want a smooth running car while in vacuum and extra smooth power in boost... I had timing problems and ignition problems for the last 5,000 miles and it made me hate the car. Nobody could figure it out.

Also, (I know this is long) since the megasquirt can control timing can a map be made to mimic the stock ECU? For a failsafe or troubleshooting map. While NA I would like to increase ignition advance to ~20 degrees with higher octane fuel just to see differences with ignition timing under WOT. My car currently hits 17 degrees and no higher.

I really appreciate any answers and I hope this thread can be usful in solidifying people's understanding of the megasquirt. Many people think its a magical fuel control device that easily solves all the problems of boosted fuel control. While it indeed does all this, I fear it may not be as easy as it sounds. I would like reassurance in its ease of tuning.

Hey Jared,

Let me see if I can answer some of your questions.
The Megasquirt can be used to drive your main 4 injectors, or yes you could also use it as an extra injector controller if you so wished, although 4 works perfectly fine...

My daily driver is my Eclipse, which is Megasquirted for both fuel and ignition control. And for the most part it drives ust as good, if not better than stock.
You are right in what you say, in that a lot of drivability comes from the ignition setup... and with the MS now we can control that fully, so you can make it as docile or agressive as you want.

It's even possible to switch between 2 ignition and 2 fuel maps on the fly using a switch. So you could store tame and agressive maps in the car. :)

But back to your topic, the car is very drivable. I wouldn't drive it daily if it wasn't. :)

i have just the ms cotrolling my fuel. and about 2 weeks later, i drove the car from south florida to chicago. no problems at all.

You so need to tell me how to do this (or where I can find out how), Lee. Maybe I could install the switch under the gas pedal. When I floor it, Daisy goes stark raving mad or something. I like this idea...

Brian,
Remember my hidden stick shift switch? I use it now to mute the audio instantly when I need to hear something other than tunes.

I may have to alter the function of this button when I go Megasquirt. :)

since the ms can control timing... how does that interact with someone having an msd box?

It really doesn't matter if you have an MSD box or or not, the Megasquirt will work either way.

The MSD is a Capacitive Discharge box that basically manipulates the coil driver signals and increases spark energy, generates multiple sparks, retards timing, sets rev limits, controls launch, and more.

The Megasquirt feeds signals to the GM HEI ignition modules that you must use to drive the stock coil pack. You can program the ignition via 12x12 maps that are similar to fuel maps. It give you complete control over the ignition system.

You can use a MSD with a Megasquirt if you would like to take advantage of it's features, or you can run the ignition signals straight from the MS to the HEI modules to the coil pack. If you use the MSD, you will connect it between the HEI modules and the coil pack.

I'm using a Crane Fireball HI-6DI2 with the MAP sensor & timing retard system removed on my Megasquirt setup (not finished yet).

Driveability is a matter of tuning.

Lets say I have a S25G, and an upgraded head componets, like springs, retainers, etc. Can we make full use of` a bigger turbo by placing the redline at 8k or even 9k? Just curious.

That depends on the camshaft. Right now, there are no decent camshafts out there for a 2GNT with a serious turbo like a 25G. The Crane "turbo grind" camshafts work fine with a 16G or maybe even a 20G, but if you start to flow some serious air the "turbo grind" camshafts will start to feel more and more like the stockers.

Then again, you could get your own special camshaft ground by Crower or Crane - if you did that, you could design the camshaft to do anything you want, like support a higher redline while flowing tons of air.

Not even Crane 16's?? I know the "turbo" grind for Crane is the Crane 14. I thought that the Crane 16 would be more than enough.

Either way, can you modify the redline with the MS?

I don't know about you, but how many cars have you seen with the AEM EMS.?.Talk about run/idle like stock and perform better than most(almost all) stand-alone setups on the market...

also remember, most highly modded cars have aem ems basemaps made from aem. it would be great if they made a plug and play ems for the 420a.

I don't see how. Every 420A car uses a different harness, and even cars of the same model will have different pinouts for each year model. Plug and play would be a huge undertaking for AEM because they'd have to have a different unit for every year model.

Once you remove the plugability of the AEM, it's no better than anything else and worse than some.

one of the facts i like about these cars is that you cant just 'plug' in a standalone. so it actually takes knowledge to make a stage5+ 420a.

AEM is not developing it...We are (Torquefreaks). After my car gets done there is already another 420A with a star kit waiting in line.

"Over the past 8 years I've had a considerable amount of experience with pretty much all of the controllers out there - MOTEC, FAST, Accel DFI, Haltech, etc, none of which have impressed me enough to steer me away from the simple Electromotive TEC II controllers that I normally use.....until now. I was first introduced to the AEM EMS by a friend, Scott Matas, who was configuring one for his Formula SAE car. After one trip with him to the dyno to help out, I was sold. The AEM system was capable of everything I was looking for in a controller for the same or maybe even lower price as what I was using!"

Mike Sitar, TooHighPSI.com

I have used several standalone systems in the past as well as the VPC and GCC, etc. I have learned that the ability to have the computer control outputs in a controlled set of circumstances, and get feedback from the logging capabilities of the computer is by far the safest way to make reliable HP. The AEM EMS has a lot of extra input/output capabilities that allows me to monitor everything on the car. The AEM EMS gives me the feedback I need to make better choices on my hard parts to make the car go faster. Its vast datalogging capability, at 250 times a second, allows me to precisely tune the car to the point where I can go to the track, no matter what altitude, and rarely make any tuning changes. The AEM unit has helped me drop my times to a best of 8.71@169mph in a street class, street driven Talon. I want to thank AEM, and especially Jason Siebels, for all the help over the years.

How many of these do you want me to post???

Okay. So Shep uses one and likes it. So what?

The record holder for a FWD at Bonneville (212MPH) is DFI-powered. The national record holder for a drag radial (8.17@178) is also DFI powered.

Does that mean is the best? No. No more so that naming off two racers who probably got money to endorse it makes the AEM better.

Gimme a feature. Name something it does that no other standalone does that makes it better and maybe you'll change my mind.

I would like to add that any vehicle using MegaSquirt has the ultimate drivability.

Having just been given a ride in MrSlick's car yesterday (when picking up a motor), I can vouch that it idles like stock using 780cc injectors, drives like a dream while allowing for the best tunability, and is damned fast. He ran 24 psi with zero issues.

Can you do that with your SFMU? ;)

Get MegaSquirt if you are looking for the ultimate fuel setup.

Yeah it was a fun little drive... :)
Traction is a problem at 24psi ish...
I think I smoked 1st, 2nd, 3rd and 4th gears when I pulled out. :)

Look at this link and the testimonials,video links (Supra and Viper) and tell me that it doesn't change the way our cars operate...It's only been on the market for a couple years and has already influenced the competition to improve their products to compete...We won't talk about their (AEM) 6 second civic either...I know it's not a DSM but it sure tearing up track records (200 MPH+)...

How about the Megasquirts ultimate feature, It's open platform. Don't like the way something works? Grab yer nuts and change the software to make it work the way YOU want. Beat that. ;)

I found some more for you :-0

I went with the AEM EMS, in large part because I wanted to use knock sensors, and John Reed from TorqueFreaks (www.torquefreaks.com) flew in to tune the car. While I was very satisfied with the power and torque on 93 octane (860rwhp / 823rwtq), the amazing thing is that the car drives better than stock. That's right, better than stock. The car runs very, very smoothly, which is amazing with 75 lb injectors, and is a complete pussycat--until you hit the gas. There is definitely some more power in this setup if we want to do some more with the tuning or up the octane or boost, but it may be a while before I learn to manage what I've got.
I want to make everyone aware of TorqueFreaks. John, Jason, Chris and the crew at TorqueFreaks were extremely professional and easy to deal with, and I'm sure I'll have John come back out in the not too distant future to play around with the traction control and teach me some other tricks. You can't go wrong with any of these guys!

After I decided on finally going for a big single setup I had to make up my mind about which EMS to use. My first choice was using a MoTeC EMS which would have cost some 7000USD (EMS + necessary sensors + tuning) in Austria. This was an absolute no go for my budget.
I talked to various people who where into motor sports and they all told me if the AEM was as good as a MoTec it would cost exactly as much but definitely not less then half ... who would want to make less profit by selling an equivalent product for less, right?

So basically I had to choose the AEM as there was no other alternative for me. I thought that I would definitely compromise the drivability of my car by using such an inexpensive EMS. Boy, was I wrong....

After finally deciding on using an AEM I had to find the right person to dial in my "precious" Supra ... I went to every board I knew and flicked through every post concerning AEMs and it quickly became obvious that Sean from TorqueFreaks was one of the 3 best AEM EMS tuners, if not the best, which was the reason why I asked him to come over to good ol’ Europe tune in my car.

Sean really did an awesome job. The car idles perfectly smooth, smoother than it idled when it was still BPU with factory ECU. The car also cold starts flawlessly. My a/f ratios are rock solid no matter how I drive the car, over the whole rpm range. The car pulls so incredibly hard it's just awesome....

The AEM in combination with Sean's skills does in no way compromise the street drivability, in fact, the car now runs BETTER than stock, Sean even somehow managed to improve my gas mileage, the tranny shifts much faster now (like you’d expect from a sports car) and it's just more fun driving the car on the road and on the strip.

I can’t wait for Sean to come over when I finally have my new fuel setup, this guy just rocks, he is definitely worth every cent.

at first, sorry for my bad english.
I love Torquefreaks. They are awesome. My car is now so fast, it is really unbelievable. I have now amazing power since TorqueFreaks was here in Berlin and tuned my car.

The first day they find so much wrong things, we have fixed that and began to tune the car.

After the first pull in the third gear I can´t stop smile that was so so so fast, its really awesome.

TorqueFreaks have done a great job. They know to tune the AEM very well and they have also have a big Know-How about the technical and mechanical work.

Now I´m so happy, I can´t describe it. It´s really a great feeling.

Hope see you again,

I hired TorqueFreaks to come to DC to tune my car. John, a tech/tuner at TorqueFreaks, installed all the parts since I am not very mechanically inclined. My S2000 is my daily driver and I needed a quick turnaround for installation and tuning. Sean, one of TorqueFreaks' tuners, started tuning the car the next morning; getting it to start properly, idle smoothly, and free rev well. Then it was time to road tune the car. After he tuned the car it was my turn to drive and see if there was anything I didn't like. It was amazing how much smoother and more responsive the car was. Sean told me to drive it like I would in day to day conditions. After driving on the highway and stop and go traffic the car was driving like it came from the factory, but with more power.
The following morning Sean worked on the cold start and the car was responding well. We went to Curry's in Ashburn for a dyno tuning session and when all was said and done it was reaching mid to high 280's on a mustang dyno. Sean did a fantastic job with the car. It runs incredibly well and the throttle response is amazing. I can VTEC at any throttle position and I don't have anymore misfiring.

I highly recommend that anyone with a turbo use the EMS. TorqueFreaks lived up to my expectations and I couldn't be happier with the way things have turned out.

Re: TorqueFreaks

My personal experience in dealing with TorqueFreaks has been very impressive and rewarding. Like you, I have put a lot of money and time into my car and take extreme pride in it. For that reason I needed someone who could be trusted and had the knowledge & experience in tuning my car.

I thought nothing of it to flying Sean to Hawaii for my final tuning. It is worth every penny to have the final results I received from Sean’s vast knowledge.

Sean is a no-nonsense type of person, he gets right down to business and does what he enjoys doing, tuning. I was very impressed in his skills with the AEM ECU and his trusty computer. Once we had the Supra idling close to perfect he started tuning other critical areas before the first road test. I could not believe the amount of power he could extract from my car (there is room for more extracting, but I told Sean I prefer a safer margin than running it on the ragged edge).

If you want a personal verification of Sean’s work and abilities, my phone number is listed above.

Hey Sean-
I wanted to thank you and your coworkers for getting my car back up and running and for handling the situation so professionally. It’s a rarity to encounter a tuning shop that has good customer service; you’ve definitely earned my repeat business. My car is running better and smoother than it ever has since I’ve gone turbo. There is no hesitation, more consistent power down low, etc. Overall it feels like a stock car. Also, Jason was really helpful and took the time to walk me through everything when I picked it up on Saturday.

Thanks again,

Matt

For tuning, we called on TorqueFreaks. TorqueFreaks is located in Portland, Oregon. Check out their website -- www.torquefreaks.com -- for more information. After talking to four of their customers -- all of whom had nothing but great things to say about them, some of which is already posted here in the AEM Forum – we flew Sean (the owner but only one of several qualified tuners) out this past weekend to tune our cars.

Bottom line? The cars start, idle, and run like stock, with a lot more power of course -- we're guessing 300-305 hp to the wheels at 7 psi of boost. Idle, boost control, partial throttle tuning, on/off throttle transitions, etc., are all much improved and the EMS has definitely resolved our complaints with the VAFC. With O2 feedback enabled and the wideband installed, our air-fuel ratios are unbelievably rock solid across all sorts of conditions (boost, throttle position, engine speed, etc.). We take comfort in knowing that Sean was very conservative when tuning our cars. We suspect that there was more power available -- on pump gas at 7psi there wasn’t even the slightest evidence of knock -- but longevity is far more important to us than the extra horsepower.
TorqueFreaks isn’t the cheapest route for getting an EMS tuned, particularly once you consider the cost of the airfare, lodging, hay and water, but it was worth every penny. We have nothing but good things to say about them, and the fact that we now seem poised to start enjoying our cars again after months of despair really is the ultimate proof that all’s well that ends well.

Regarding the last dyno day at TorqueFreaks, I was very impressed by the knowledge of the employees of TouqueFreaks. I understand that in any high performance shop it's not always easy to please everyone everytime. I commend TF for being an obviously well respected group of professionals who I felt were very attentive to everyones questions and were definitely offering good advice for all that ran. It's nice to know that they are taking care of everything.

Hey all I just wanted to share this experience with you. I am not much at posting but thought some of you would like this info.

I was at my wits end with this AEM EMS. Problem after problem I decided to take my car (94 supra) into the shop and tune this thing. They also put on cams, Sp Built tranny, 850 CC squirters, 3.2 k stall, Greddy T-78 ect. etc. After 8 months I finally got my car back (don't ask it's a long story.) When I drove the car I was suprised how laggy it was and no response down low. I thought I had gone too far. I thought my car would never be the same. The tranny shifted so hard and so often and it took forever to spool that turbo. My idle surged and tip in fell flat on its face. I called Chris at HorsepowerFreaks.Com for some help. He put me in touch with Sean McElderry who without a doubt, is in my opinion, one of the Best EMS Tuners I have ever met. I called him and after checking a few references (all who were ecstatic) I arranged for Sean to come to PA.

When Sean was done with this thing it was a monster, Throttle was snappy, Idle was perfect (14.2 - 14.7 /1 no matter what you turned on) This car runs as good or better than stock. Most of the tranny isues were solved and at cruise it was in the mid 15's / 1 AF. We tuned for pump 93 octane and then C16. There is almost no lag and at a dead stop with no reving we went 0 to 100 in what felt like 6 seconds. At cruise boost is instant with the AEM controlling everything. Nice linear boost curve almost no tire spin but it pulls so friggen hard. I never imagined my car would run this good. This thing is flawless. Hell Sean even has O2 feedback working perfectly, so good in fact that we pulled a fuel line off my NOS to empty the fuel tank for the C16, fuel pressure dropped to 15 and car was still idling at 14.2/1. Sean is on this site often so you can PM him or email Sean@torqueFreaks.com. I highly recommend his services. Sean thanks so much for giving me my car back.

I organized a group tuning weekend in Detroit last month and I flew Sean from Torquefreaks (the tuning strong-arm company of Horsepowerfreaks) out to see what he could do (after reading some very positive posts on the aem forum). I was very impressed to say the least.

For some background, I purchased my EMS at NG02. I have been actively using the EMS for about a year, and have been able to get several other 3/S cars running on it as well. After months of fumbling, I had my car running to what I considered to be about 75% of its capability (before upgrading to v1.03) but I had some issues I was never able to nail. After pulling my hair out for a year and growing some new gray ones, I wasn't ready to go through that pain again on v1.03. Flying Sean out to Detroit was my last hope to regain faith in this car that I spent 2 years building from a broken down heap.

Sean had my car running significantly better in a matter of a couple hours. After working through some software issues on the EMS, my car was probably at 90% off its capability in one long evening! To try and squeeze every last ounce of tuning out of Sean we went to an AWD dyno later that weekend. We discovered my Hallman mbc was bad at high boost and Sean had my GM boost control solenoid working in a matter of minutes. Sean was able to squeeze 384 hp out of my car at 16psi on 93 octane pump, which isn't bad considering he also had 3 other cars to tune the same weekend (3 days of Sean's tuning time). I also have a couple mechanical issues I need to iron out before I try tuning again (high IATs and EGTs). Even better, the car starts like stock, has no bucking problems, accel/decel issues, and gets as good as or better gas mileage than stock!

I hope this helps give an idea of what Sean can do with our cars. Please don't keep Sean too busy though, since everyone around Detroit wants him to come back first thing in the Spring when the snow melts! You really do get what you pay for.

For those that question if it is worth to pay TorqueFreaks to tune your car, let me say that it will be the best money you will ever spend on your car. I know it was for me. I actually did not realize just how great a job Sean did until I recently and accidentally uploaded the wrong maps into my car. What a difference. It was this mistake that has prompted me to write this letter. Here is my testimony.

I have a 94 Supra TT with BPU, AEM ECU, HKS ignition, wideband O2, and some other small goodies. I have had a local shop, with a chassis dyno, tune the car from day one. After repeated attempts to properly tune the car, at a cost of $1,000, I was ready to pull the AEM ECU out and throw it away. The car was hard to start, idled terribly, stalled repeatedly, had black smoke pouring out the back, bucked wildly under throttle, constantly hit the rev limiter, and all and all was no fun to drive. It was actually embarrassing to drive the car.

When Chris at HorsepowerFreaks recommended Sean of TorqueFreaks I was skeptical to say the least. I was so sick of the AEM that I did not think God himself could convince me to keep it. After talking to Sean on the phone I made the decision that I was this far in why not at least give him a try. I purchased Sean a ticket to Tampa. I picked him up at the airport in my Supra so he could see what he was up against. After a 35-40 minute drive back to my house he gave me the option of either working with my maps or going straight to his. I thought that this was a dumb question as I had $1000 in dyno time on the current maps, they couldn't be that far off. Or could they? I figured that it would be much harder to start from scratch, but left the decision up to Sean. He felt it would be much easier to go with his maps. In 10 minutes or so he adjusted his maps to what he felt would work in my car and proceeded to upload it.

Not only did the car start easier it idled almost perfectly! I could not believe it! In 30 minutes or so he had the idle better than it ever was stock! We spent some time (4 hours or so) making adjustment after adjustment. It was amazing to watch him run the AEM software. He knew where every adjustment was in the program and what it would do. The monkeys at the local shop spent more time trying to find the right thing to adjust, and then whether to adjust up or down, then they did actually making adjustments. By the end of the day the car was running OH SO SWEET! It started easily, idled perfectly, pulled harder and smoother than I ever thought possible. One of the biggest improvements: NO BLACK SMOKE (for those who don't believe this can be done in a Supra, I beg to differ)!!!

The biggest improvement was with out a doubt the smoothness of the car. It is hard to describe without being in the car, but it just feels smooth. There is no drastic power swing but rather a smooth progression of power. The power comes on at about 3500 RPMs and just keeps coming. This car drives actually drives better than stock. My fuel mileage has even improved. On the freeway the car motors along like it was still stock, until you put your foot into it.

All I can say is Thanks Sean. I went from being ready to sell my car to never wanting to part with it. It is actually fun to drive it again.

Thanks again,
Frank Joseph

Those of you considering hiring Sean's tuning services I can only say he is a top of the line professional at what he does. (else i wouldn't have hired him right?) I've heard on many accounts he is of maybe 2 or 3 other individuals in the USA that can tune to this caliber. I remember sean telling me on one of the very long nights fixing cars that he logged over 200 hours on his own car learning all the ins and outs, and tricks before he went out to tune others cars. From this you could say he really does know from first hand experience, on his own car how to tune Your car.

I'll admit I am very novice when it comes to the AEM, I hope to learn more in the future, but Sean gave me a wonderful car to drive, and by all means I was extremely satisfied with his attitude, his humor, his professionalism, and his respect for everyone, their situation and their car. I found him to be very down to earth, very fair, and an all around good guy. He is in demand, so catch him while you can.

Those with no AEM knowledge or experience, you lose nothing with this monster ECU. Lot of people think by upgrading, you compromise. After everything was said and done, if I had to drive it not knowing it was mine that I was driving, I would say it was a different car, no joke. Everything about the car, idle, response, is different and sooo much better.

Thanks sean!

All in all, yes, you do get what you pay for, and you pay a good penny with Sean, but it is worth it. Get your plan together, confirm your setup is working, and call Sean, you won't be dissapointed, I'll guarantee it.

My decision to get the AEM was based on the fact that I have locally one of the nation's best tuners with the AEM. The most important thing in owning a stand alone is how it gets tuned. It's so easy to change one cell and then spend the next five hours trying to track down where the problem is. I did not want to give my car to somebody who has a track record for blowing motors.

Now that I have been running the AEM for well over one month, I must say that my car pulls harder then ever before. Even at low boost my car has more power than it did with the G-Force. And I am able to do this without running the safegaurds I was before (toluene, water injection, J&S Safegaurd). I am making my power levels on 92 octane unleaded now.

As for Sean’s tuning, I must say that he tunes a car comprehensively. Every aspect gets attention. The fact that Sean has tuned many cars with the AEM provided me with a level of security that you do not get with the run of the mill tuner. One aspect that obviously puts sean tuning a step above the rest is my car's drivability. My car idles BETTER than with the stock ecu or the G-Force. I do not have the drop in rpm before it stabilizes when I let off the throttle as I did before.

Personally I would not want my car to be run with any other stand alone. The aem has the most bang for your buck in my opinion. As for Sean’s tuning, I have recommended to a few other MR2 enthusiasts that it is worth every penny to have him do your tuning. Not only will he do a professional job but he will provide a sounding board for issues that come up in the future.

maybe you forgot what dino said.

list what feature it has that makes it better then the other standalones.

lets also figure cost efficiancy.

can you really beat a full (f/i) standalone for under 300 dollars?

wow that was a waste of a lot of space...

no one said the AEM EMS sucks. it does a great job of what it's made for. it's also expensive and does not currently support our platform.
