that's amazing the Pettit ECU is that fat.....I guess they want to make sure you don't blow your engine, at least until the injectors are maxed

at 16 psi with the stock injectors this guy must have been at the very limit of engine failure

 

also, I wonder is the "unlimited" ECU dumps more fuel near redline than the standard 14.7 fuel cut computer, which is what I have

 

I did not intend to run 16 psi(turned the boost controller up a little too high) I am not comfortable with the 13:1 AFRs. I dont ever like to see anything over around 11.5:1 AFR. I was really surprised that the pettit ECU would even run that lean at 14 psi. I know that the injectors are probably maxed. I could MAYBE put in an adjustable FPR to put more fuel into the motor, but Id be more comfortable just installing bigger injectors. The pettit ECU is good up to a certian point, which I have surpassed evidently. Looks like its time for a power FC!

 

I changed it RIGHT before going to the dyno

 

Add an Apex'i AVCR you can control boost totally from baseline to redline. The power FC would be good too. Did you have a lot of turbo lag?

 

oakridge,

have you had your injectors cleaned and flow tested?
