#1, "Megasquirt stuff... Looks like I'm almost ready."
About a month ago when I was trying to get my car back on the road, I broke my old IAT sensor - the therads broke off in the manifold and the rest of the sensor was junk. Good thing I had a spare upper intake manifold around, because I couldn't get those threads out for the life of me.
So, I brought the disgruntled manifold and the GM IAT sensor to my local machine shop and they drilled and tapped my "old" manifold to fit the larger GM sensor. I like how it turned out. Looks totally stock!
There's the board. It's been broken for the past few weeks, so I found the time to debug it and discovered that I was powering the board along with 4 injectors off of the stimulator board, which has 2 tiny PCB traces for +12 and ground. If I designed it, I would have made it more like the flyback board with a power plane and a ground plane on oppisite sides of the PCB. Oh well. I fried one of the cheesy power traces while trying to pull enough current to drive 4 crappy old fuel injectors. Fixed. I'm now running the 022e4 code, I will start off with fuel only, then I will hook up the ignition system. I have no idea how stable this code is, it's a new release. Hell, I have no idea if this entire setup will work at all. I've never done this before. However, everything seems to work as it should on the stimulator, but we'll see how it works in the real world. Hopefully I'll get it done over the long weekend. Anyone have a VE map I can start off with? I have stock cams and will be using 780 cc/min injectors.

I like the megasquirt system, everyone has been getting it. I want it also, but am still learning about it first. Someone should do a post on everything that is needed for a complete set so everyone can understand what to get. Glad to see alot of people helping out and reaching higher limits with the 420A.

Amen to that brother it took me 3 days to figure out ms stood for megasquirt. That is to add that I didnt wanna look like the BANME! fool I am. Who knew 420a's would be so much different then the old 4g63. Ahh the N double oo and b word auto icons ban me very nice lol.

Took me about a day and a half, maybe 50% of the time was spent fixing other things. After about 4 hours of work I was about 1/3 of the way done last night when I went to UMass Amherst for a party. I got back this morning, worked most of the day, and finished up around 9:30 tonight. I moved my ECU to the battery tray and made a little bracket for it. The actual MS wiring and other hardware went pretty smoothly. If I was just doing a MS installation (remove intake manifold, change injectors, route the wiring harness, clean up) it would probably take 4-6 hours.
I was suprised that the car started right up the first time. It idles very rich right now. I took it for a drive, stayed out of boost, and I made it around town with no problems. Not bad for a VE table that I pulled out of my ass. I don't think I ever saw the AFR any leaner than 13:1 At this point, it's all software. Lee tells me that the 022e4 code has some bugs in it, so I'm probably going to load an older revision and try that out.

Awsome! Did you copy Lee's tables to get you started since he runs the same size injectors? Man, I can't wait to get mine up and running..so much fun I am planning on using my AEM UEGO gauge's 0-5v output to use as a WB sensor input to the MS too..that will be nice. You can put in A/F ratio numbers in the tables for boost pressure right? So you dont have to use pulsewidth correction numbers, but target A/F numbers??

Nah... For a VE table I looked at my old 034EFI map, took the table, put it into Excel. I called the highest number "100" and the lowest number "25". I then resized the table to get it to 12x12 and threw it into the VE table in the MS. "100 and "25" for VE numbers I just kind of picked out of the air. The scary thing was that after I got out of idle and started cruising around the EGO correction or "fuel trim" was actually less than +/- 20, so it actually of worked for a base map to get me started.

As far as being backed up on orders goes... I'm hoping to get fully caught up within the next 2 weeks. Right now I'm waiting on some parts to come in. For anyone that needs a 780cc basemap that i'm running right nowyou can find everything you need at the following link: http://www.2gnt.com/www/slick/files/ms.zip Lee.
Hey Lee, the link you are talking about for the injectors, is that the one that I posted?? If so, is this a reputable place? Just never heard of them..
EDIT: nevermind..i'm out of it The one I posted are a bit cheaper, but not sure about the dealer hehe.. The ones you got, do those fit the stock rail/manifold like stock? I can use the stock injector harness also??

The ebay injectors were the ones I was talking about.
They are 4G63 injectors, so they are the same as 450's. You have to use the 420A o-rings, and not the ones that come with the Delphi's.
They will fit, just a little tight. I put mine into the rail first, then put them into the intake. Easier to do with the upper intake off for sure.
etx got the same ones... he didn't believe they would fit.
At this point, it's all software. Lee tells me that the 022e4 code has some bugs in it, so I'm probably going to load an older revision and try that out.
