Help. Need baseline tune

[jpb1972]

Ls3 Camaro. Btr blower cam ported stock heads with Paxton blower pushing about 10 psi. Anyone have a baseline tune that could help me out? Car won't idle worth a s**t.

Post your tune! You will need to do some research on idle tuning.

Try adding 200-300 to the target idle speed table.

The adjust your idle airflow minimum. Try multiplying it by 20% (1.20) If the idle is still rough try 10 or 15% more until you are happy with the idle.

You will also need to update the startup airflow using the same steps as above.

Idle spark advance may need to be increased.

Thanks man. That should help. The tune I'm running on was done with the blower but nothing else. The cam and heads are the new editions. Will try and post tomorrow. Right now I'm relying more on the maf as my VE is rough.

post your tune and current idle log '




log after 5/10 mins of idling

Glad I could help!

Ok, car fires up but I'm having an issue with it falling on its face after a rev.

Tried upping timing in base spark and coastdown, not a big change. Multiplied idle air and idle startup, started mult by 10 until car stayed running on its own.

I'm kind of in the dark because I don't know what kind of increase is typical. I may be flying right over the numbers where I need to be, not sure.

Here's tune and idle log.
