I have a 00 FRC Vette w/ A&A P1SC kit and the car was tuned at ECS... I got HP cause I was having some knock issues and the idle is really rich...


How do I go about lowering the fuel for idle?? I did a search and there was a couple of ways but I don't quite understand...

Also I have 42# green top injectors and the MAF has been re-scaled...

What are ALL of your mods, I'm going to bet you don't have CATS...

You need to decrease the PE table in the idle RPM's. Have the 42lber's been re scaled yet?

With zero throttle he likely isnt in the PE table anyway!? Dont you mean VE table?

what is super rich at idle?

what does the WB read?

Yeah VE can be pulled back some at idle, what fuel trims are you getting at idle?

If the cats are gone, make sure that COT (cat over temp) is disabled.

You need to rescale IFR not the MAF table. Injectors wont affect the airflow into the engine. You should correct the maf based on actual airflow measured by a wideband % error or compared to a correctly tuned SD value etc.
