Hi Gents, been a while since I've been on. Please look @ this tune. Am trying to diagnose why the car will jump to 2200 ish RPM & hang during the entire trip of that car's start. It happens randomly, but, only after car has warmed up & on a second or third time starting for that day.
Have tried...
-ECT spark table mods to subtract spark under certain ECT conditions
-idle air airflow mods
-engine overspeed spark reduction
-IAT mods
-start up mods
Am pretty sure that it's IAT/ECT related, but can't pin it down. Should also note that if the car is started a number of time immediately after the initial high speed hang (2200 ish), I can get it to stop doing it. If the car is driven without restarting to eliminate the hang, it will hang for that entire trip.
Thanks for looking
