I'm maxing out my 30# injectors and my superfueler at 5000 rpm. So I am purchasing 42#ers, but I need help with the reprogramming to make my car idle with the 42's. Could someone tell my what all needs to be changed. Or sent me a file so I can do a compare and figure out what needs to be changed.

Thanks,

I just updated my injector flow rate in the ECM constants table (TunerCat) from 24.91 to 37 when I put in my 37# injectors on Saturday. It runs just like before, perhaps idling slightly better. My only complaint is that the engine turns over a couple more times before it'll start when it's cold. I'm messing with the "initial startup afr enrichment" (going richer right now) to see if that'll help. I'm going richer because my O2 voltages are in the .4's after first starting up, and I think they can afford to be a little higher. We'll have to see.
