Harry buscema Posted September 24, 2020 Report Share Posted September 24, 2020 Hi there, Having trouble figuring out why when my car is above 77c my idle kicks up to 1.9k rpm from the target idle of 1.1k rpm. Is there any specific setting that I should be changing that would effect the idle depending on temperature? Thanks Quote Link to comment Share on other sites More sharing options...
Adamw Posted September 24, 2020 Report Share Posted September 24, 2020 Attach your tune and a log. It is likely your base position is wrong and therefore pushing the idle above the lockout so idle control never kicks in. Quote Link to comment Share on other sites More sharing options...

Vaughan Posted September 25, 2020 Report Share Posted September 25, 2020 You don't appear to have an ISC valve setup and so are only using ignition idle to control the idle speed. Looks like it's not dropping below the Idle Ignition RPM Lockout and so the ignition idle control never pulls the ignition angle (and as a result engine speed) down. Maybe try reducing the ignition table values in the idle area of the table. Quote Link to comment Share on other sites More sharing options...

Adamw Posted September 27, 2020 Report Share Posted September 27, 2020 Try the attached file, I have flattened out the ign table around the idle entry area and change the idle ign table set up. For this to work well you will want toi get the engine warmed up, then adjust the throttle stop screw while watching the idle ign table in PC link until the cursor is bouncing around as close as poss to the 10deg cells in the idle ign table. Say somewhere within that pink window below. Try this.pclr Quote Link to comment Share on other sites More sharing options...
