I have been having an issue with hot starts that I cannot for the life of me resolve.
The car has afr 220 heads, a torquer v2 cam, stock ls2 intake headers and ls3 injectors.
It starts well cold and starts just fine hot if you turn it off and then start it right back up. But after sitting for at least a few minutes or an hour while still hot/warm it will not start without cranking forever. Hot quick restart it will crank for just over a second before firing up. But after sitting I will have to crank it 3 or 4 times before it does eventually fire. I do have log files and a tune I can attach. It looks to be lean while cranking, atleast initally but does richen up after some cranking, not sure if that is just the sensor being after the header while cranking at lower rpm. Ive added alot of fuel in the tune without seeing that initial cranking richen.
I have added startup airflow, lowered and raised cranking VE, added to the lower row on my main VE table, changes cranking spark some, and played around with the Cranking FA multistage table. I am not really sure what else to try, once it is running it idles well, and drives overall good. Some bucking at slow speeds, but otherwise AFR's are pretty close. Looking for any advice, I am lost on this one!
