392 cam swap intermittant hard hot start

[Flipper7]

Hello, I have seen some of the previous threads on after cam swap no hot start issues. I have a vehicle that has Tsp cam swap with ARH headers and exhaust. It has an intermittent long of poor hot start. Sometimes It lights off great, other times long crank no start. If I Pedal to flood clear it, it will fire up. So I started to trim Startup Inj Pw in the coolant temp ranges that I was experiencing the hard/no start. It seems really close. Sometimes I can get 10+ hot starts in a row, and then I'll get a crank no start. Has anyone had a definitive fix for this? Maybe it needs additional starting airflow? Are you guys adding airflow at the Startup Adder (Starting/Cranking) under the Etc Airflow? Would you add is under the 0V or 1V rows?

try adding airflow to the 0v cell 1st

if you have a good starting, good running vehicle, with a intermittent crank no start problem, i have found that the issue is seldom tune related

I added small voltage offset to the 1st cell and it has been solid for over 20 starts so far. Previously it would have done it within 5-6. I'll keep an eye on it , but at the moment it is batting .1000
