Having some trouble getting the idle sorted out on the following combo:
1999 P01 3 bar
5.3 sloppy stage 2
Whipple W140AX with 3" pulley and 90mm holley DBC
Got the VE close, set the IAC 30-40 hot with the throttle body screw then reset the TPS and IAC, .5v closed.
Attempted to dial in the IAC effective area, its fairly close as desired airflow is close to running airflow at idle.
Idle airflow is close, I know it needs a cold start but the thing oscillates or surges at idle like crazy.
I tried increasing and decreasing Idle Airflow with no success.
From the log you can see it does it from startup and anytime i hit the throttle and let it return to idle.
Any ideas? VE not close enough, spark, IAC effective area, or Idle Airflow?
Thanks!
