    Wont start once warm without hitting the gas. Stage 2 cam

    I am having issues getting it to start after the engine is warm without hitting the gas a bit. I turned the Target Idle Speed table up 50 rpm but that did not help. What tables should I change to correct this issue? Would I need to change the Startup Idle RPM or the Idle Spark Advance tables? Thanks in advance

    Look at your Startup Cranking spark table. I had the same issue when I cammed my car and had to reduce the timing at the higher coolant temp ranges to -10 to -15* advance. Starts warm now no issue.

    Bump up your Startup airflow table also
