Thread: Target Idle

  1. #1

    Default Target Idle

    Hi. I put a ProCharger, Chevy Performance LT4 hot cam, and Holley Dominator in my '92 Corvette. I got a base tune in from speaking with the the Holley Techs. I have two issues. First, my idle is low about 900 and it pulses. No matter where I set the target idle, it doesn't seem to change on the car. I can see it change live on the graph view. When the car is running it has a little dot hovering on where I have it set at (1500 RPM), but the car is idling at about 900 RPM. What other parameters do I need to adjust to change the idle? My second issue is from a stand still when I hit the gas hard - moderately, the car seems to almost die for a second then it goes. Thanks, Mike

    Acceleration Enrichment can't be tuned until the Base Fuel Table is well tuned.
