This is my new 5.7 224/228 114 cam 243 heads 60lb inj for now 4l80e trans. Got it to idle at 850rpm when I shift it to reverse it dies. It idles ok but just dies when put in gear.

 

What all have you tuned so far? Did you tune running air flow (RAF) in gear? Have you played with timing at all? What is your timing doing when you put it in gear?

 

All that i have mess with is only trying to get ve in line i used a corvette ve stock table and base runing airflow table. ve was off a little so now it will idle but stft are still in -10 to -12. would like to get it a little lower before I use my wideband to fine tune it. Havent played with timing thought about adding a 2-3 degrees at idle. Didnt look at timing when I shift it into gear since it just dies.

 

Timing is at 26 when I shift in to gear. I added .3 across the board on start up initial airflow and 10% to base running airflow table. Starts much better but still stalls when put in gear. My stft are 0 to 6% now.

 

So you have not actually tuned your Running airflow then? Did you have 10% over what you already had from before or from stock? What is your Idle rpm in Gear.

 

Timing seems a bit high at idle. That can add to your idle woes with surging/lurching. Try 20-22 ish, and actually tune your RAF tables.

Search krambo idle tuning.

Didnt tune running airflow because ve was off I read that it must be good before you can tune RAF. Yes added 10% over stock and idle rpm in gear is at 850rpm.

 

Yeah went back to check timing and tables didnt seem right. So started with new ones.

 

It's kind of a back-and-forth thing. You've got to get it idling well enough that it doesn't stall on you constantly while tuning the VE, MAF, etc. Then once that's all good, do the RAF again.
