Alright, I've been kinda quiet of late... that's becuase I've been working on some very special development code for the Megasquirt... Well the big news is this:
We now have code that will deocode and use the factory Crank Position Sensor...
What does this mean? Quite simply the Megasquirt will be able to run full fuel and full ignition control! Using the stock crank sensor!
Along with this new code and hardware mods come the following features:
1.) Full fuel control - 2 x 8x8 fuel tables, soon to be 2 x 12x12 tables. 2.) Full Ignition control - 2 x 12x12 spark tables, selectable during operation. 3.) Launch control - variable 2 step launch control / studder box system. 4.) Target AFR - closed loop control under boost using a wideband o2. 5.) Knock detection - Detect and respond to knock, programable ignition retard. 6.) Overboost protection 7.) Boost Control 8.) Fan Control - Programmable 9.) Shift Light 10.) Nitrous control - Dry and Wet 11.) Anti-Lag control 12.) Water injection control 13.) Temperature Compensation - Of course!
The Ignition feature is still undergoing testing and development... the Crank decoding code is running on my car as we speak, with full ignition to be tested in a few days. All the other features have been tested and are present and working. Soon I will also be working on testing a 3 Bar MAP sensor and setting it up for use in the code...
I thought I would let everyone in on what was coming int he very near future, so that people could make an informed decision about what to do with their fuel system. This post is not aimed at derailing any other fuel systems... in fact for some people I would suggest they go with something simpler... While you do not have to be a rocket scientist to run a Megasquirt... it is not for everyone.
If anyone has any questions on the Megasquirt system feel free to contact me via email: turbo2gnt@gmail.com
And I am currently taking orders for Megasquirts also.

I want to be the first to thank you for these great developements and contributions to the 420A community. This is some of the coolest shit to happen in a long-ass time. This means that we'll finally be able to make some BIG power with the 420A.
The ignition control, 3-bar MAP sensor, and 12x12 tables are very important to me. As soon as these are fully operational I'm sold on it.
Actually, I'm very interested in helping test these new components. I have extensive modifications and may be able to contribute in some way. Let me know what you currently have available for sale.

Thanks for the vote of confidence dougie.
The ignition control and 12x12 tables will be here very soon, and probably before the 3 bar map sensor... partly because I dont have a 3 bar map to test with yet... I need to get one.
As far as how you can help, let me know what you have in mind... Also, my stocks are low right now, and parts are being ordered. I may have 1 or 2 MS units that are not spoken for... but they will go very quickly. After that it will be first come first served on the new batch coming...

These can be used in other cars also right? Like if I install one in my Eclipse, but I plan on selling it in 2-3 years to buy a BMW, could I run the MS in the BMW?

I like the looks of all of this new info, and I think I will make this upgrade at some point as well. My only question goes back to the whole big injector issue. Do you have to run an insainly low fuel pressure to idle them or are you controlling it all through pulsewidth with the ms? I also want to thank you for the developement on this system. I still believe the EIC is a great and worthwile system, but for my future power goals it seems the upgrade is inevetable. (SP?) Also is the MS capable of using any wideband O2?
I edited to the wiki!

>>My only question goes back to the whole big injector issue. Do >>you have to run an insainly low fuel pressure to idle them or are >>you controlling it all through pulsewidth with the ms?
The MS controls injector pulsewidth so you can run whatever fuel pressure you want, within reason. I'm running the Accel DFI and RC 720cc peak/hold injectors and my base fuel pressure is 45 PSI. MS can do the same thing just fine.
>>Also is the MS capable of using any wideband O2?
I think you'll need the MS2 for that. I know the UltraMS is supposed to take it a step further and have drivers for Lambda sensors.

I'm running 780cc injectors on my 2.0 420A. I have static idle fuel pressure set at 43.5 psi.
With the Megasquirt you run normal fuel pressures... that's what it's designed for.
As far as Wideband, yes you can use a wideband with the normal MS. Any normal wideband controller that can outpout a 5v wideband voltage can be used. I'm using a TechEdge v2.0 with my MS...
With the latest code you can even do "Target AFR" basically you tell it what AFR you want to run... and it adjusts closed loop under boost if you want it to... You still need the VE table pretty close though obviously.

The code right now offers 8x8 tables... Very soon it will offer 12x12 tables.
Now of course MS interpolates between these points...
And yes, an 8x8 table is enough points to tune a turbocharged motor... If anyone says otherwise then I'd like to hear their arguments for it!
Any other questions?
Oh and Siu, one other advantage over the PF is that with the MS you can make changes on the fly, whilst running... with the PF as far as I know this is not possible.
#246, "RE: Megasquirt - What it can do..." In response to Reply # 9
you can make changes on the fly with the PF. one advantage that the Pf has over MS now.. the PF can do over 4000 points of adjustment to the fuel curve.
if im reading your statement right.. it seems that the MS can only do 64 points of adjustment.
