Aright guys. I'm having issues and I need some ideas.
Basically, the car wont stay running. If it dies after a few times it will just crank and not start untill it cools down for over 2 hours. I've swapped over my friends distributor, same problem.
Right before it dies i try to give is gas and it still dies. Doesnt sputter or anything.
Turbo 5.0 swapped bmw e30.
stock A9S, 44lb injectors
AFR @ 12.5-14.5
VAC @ -16
IDLE @ 1200 wont idle any lower. IAC is flipped for clearance.
Fuel Pressure @ 40psi with vac off nipple.
Base timing 10*

So you are running untuned with forced induction on 44LB injectors? Alright. Where to start?
Lower timing, adjust TPS Voltage, what ignition are you using?

I know driveability will suck, but it should at least idle without randomly shutting off.
MAF is fresh from pro-m racing. I bough a used maf and the calibration numbers were wiped off. I thought it was a mismatched maf. I ordered a new one calibrated for 44lb. It only improved a little.

idle and startup is the biggest issues a tune will fix, when it cranks and won't start try holding the gas pedal to the floor so the fuel injectors turn off, it's probably got too much fuel to fire off when that's happening.
