Hey guys,
Doing some tuning on a new motor and have noticed off idle quality and off idle response are very poor. I've gone through a couple idle threads here and checked things out but am not noticing anything obviously out of place. It doesn't like to idle below 1200rpm (currently using the throttle stop to keep it running) and it's very difficult to get the car moving from a stop. Can anyone tell me if I'm missing something?
The other issue I've noticed is that the tune is pulling timing due to high IAT's. Are my settings conservative on the IAT retard table or should I investigate piping in colder air?
Tune and log are attached and the build is as follows:
347ci ls1, 11.3:1
Lingenfelter ported 317 castings (cathedral port)
2.02" and 1.57" valves
LSXR 102 intake manifold, 102mm throttle body
Cam - .634/.637" lift, 233/[email protected] duration, 113 lsa
Many thanks for any help you guys can give.
