Ive been tuning my Z28 its got SLP CAI kit MAF headers and exhaust FAST fuel rails and 42 lb injectors by Lucas but i turn the car on it kicks over really nice and idles good but as soon as i either give it just a little gas or move it to reverse or drive it dies. Am I missin somethin stupid easy mechanically or is it a tuning thing i can do to fix this i have HP tuners. Any help or ideas would be greatly appreciated thanks guys.

change your injector flow rate which is located in the fuel control menu to 42lb. but remember you have to calculate how much 42lb is in metric terms if your hpt is in metric mode.

also in the idle menu under idle airflow under idle airflow vs ect menu make everything after 68F 15.

and you should be fine

i think you should be fine with these numbers:

20,17.5,15,15,15,15,14.52,14.52,14.52,14.52
18.1,15.75,15,15,15,15,13.5,13.5,13.5,13.5

the ifr looks fine...but im confused as to why you'd need an 800 rpm idle in a bolt on automatic car...honestly not sure why its dying on you.

Recon12thman

ok i was just settin the idle on the high side to see if i could keep it from dying thats all

Recon12thman

is there anything you could thing of

Recon12thman

yea these numbers didnt do anything really it still started up nice but as soon as i gave it some gas it died
