So I?ve been learning and tweaking the tuning on my LQ4/9. It has a TSP stage 3 low lift and other mods. It cold starts good but after driving somewhere and shutting it down it requires a little throttle blade opening to start. But not all the time. It?s hard to pinpoint exactly when it does it. I added some timing and it seemed to help a little but not sure that is the whole issue. Any pointers on what to look at to adjust?
Go to the Idle tab and increase the Startup Airflow Initial table at the operating temperature where you see the problem.
Any codes? May have a camshaft position issue p0340

No codes at all. Runs great otherwise, just doesn’t want to start as easily when warm. But it is kinda picky and random and sometimes, on rare occasion acts the same way first thing in the morning. Maybe camshaft sensor going bad? I may look into that aspect.
