Just thought I would update everyone on my progress.

I got the car to idle!!! Granted, it is super rich and at 1200 RPM but it is staying on!

Doing some research on MSExtra I found this site:

http://injector-rehab.com/shop/lag.html

Completely lost and frustrated I used the table on that website for my Accel 83 lb injectors with a value of .85 for lag time (dead time). Right away the car held idle.

Of course, it stayed on but was surging from about 300 RPM to 1500 RPM.

Using what you guys said in this thread I then blocked the IAC. Right away the car idled smooth with no surge (with a 4% throttle).

My next step is to hook up the IAC to MS and find some issues with wiring... I am getting 19.2 AFR on Megasquirt with my AEM Uego but my AEM Uego gauge is reading 11.2 AFR at idle.

Additionally, my temperature and MAP reading on MS are reading much higher than they actually are:

Coolant Temp: Stock Reading = 202, MS Reading: 293
Intake Air Temp: Stock Reading = 109, MS Reading: 169
MAP Pressure: Stock reading = 13?? (Don't remember, but it was much lower than MS), MS Reading = 39

Do you think the temps and MAP are due to wiring or calibration? Same with the UEGO??

Thanks for all the help guys!
