Hey guys
04 gto h/c header procharger
Idles great after 5 mins (startup lean goes way lean 16 afr++++ the settles 14.6 )
but after that if you tap the gas responds nicely, then stalls
throttle cracker zeroed, and runing about 25* idle timing. iac counts about 60
WHY???:banghead: :banghead:
what no love??
well I think I might have to adjust the throttle screw some. And add more fuel.
That should be right?? anyone.
cam has a lot of overlap, this is a Nick williams 90 TB, and the old throttle had the blade drilled.
Any other tips on dealing with extra load of the procharger at idle??
Do a cold start scan till operating temp using this idle config file. Don't touch the gas pedal, just let the car idle. Is the car in closed loop? Are the fuel trims & LTFT map and rpm boundaries set up for you camshaft?

Use the same config, and use the RTT feature. input those idle airflow numbers, still get a -1.06 LTIT.
Right maf is failed for SD tuning, but when you start it right way goes 16.5 afr and few minutes later back to 14.7.
I thought had the ve right in that section but, we stopped to update the ve(part throttle stuff 2000 rpm on up), start it and STFT went 52+ when we first started it was -3(earlier that day)
Look over your Afterstart Enrichment values. If you increase the fueling and decrease the decay time, you should be able to get the AFR's out of the 16's on hot restart.
