Scaling Big injectors with UTEC
I installed my 650 cc injectors today and I cant seem to get them scaled, I have a 11.5 afr at Idle and it runs kinda crappy.
On my open loop fueling parameters the Injector scaling column isnt there anymore and the Injector Deadtime parameter is also missing, I am running version 2.8
I am already running -24 in the 0 Load Column, and it doesnt get any better with lower numbers.
Any insight?

yes i am already running the CJM fuel return, I bought it from you Sharif
i will try less fuel pressure, currently i am running ~52 psi base

oh yeah last question, should this affect how much fuel will be delivered at full boost, i seem to be running a bit leaner even after I compensated on the fuel map for the fuel pressure drop.

yeah i got it to -24 right now, everything works fine when the AC is on bc it brings the RPM up. Its back at 14.7 afr, looks like i will have to get the idle raised up, thanks for the info though

Reviving an old thread (I searched):
I just also swapped my APS injectors (380cc??) to RC 650cc. I had all zeros in the 0% column before and it was running just fine. I tried adjusting it to -20, -30 and all the way to -60. It is now running a lot better (idling ~14.7), but it seems to smoke a lot. Can that be because of too much fuel? How low should I adjust it and how low is "too low" in the 0% column? I know all cars are different, I'm just trying to get a feel for what it should be set to. I'm using the stock fuel system and APS fuel pump/regulator.
Thanks!
