Hi All

I had the car out today for some light cruise tuning. The car idles very smooth.
Much better than the SDS EFI system. AFRs are bang on. I was having 2 issues.
Car would stall on occasion on tip in. I believe it was being caused by the accel enrichment. I have since turned it off. Other issue I was having was hot start.
Car would stall, and I would have to crank and crank the engine with part throttle to get it started.

Can someone please explain how to setup Priming Pulse, Cranking Pulse, ASE, and ASE Taper?

I read that the MAT Air Density Table is used to address hot starts.
