OK then.

Let's talk about the part that Mike and I have both tried to figure out: my cold start issue.

When the car sits for a day or so, the engine cranks for a long time before starting. 5-6 seconds or so. When warm, it starts in a couple of revolutions, like < 2s.

I've looked at the fuel enrichment, timing tables, etc., and all seems reasonable. Mike has looked it over too. I'm using a FAST XFI, FAST eDIST, and FAST Crank Sensor Convertor (that emulates a crank trigger setup from the factory LS1 crank sensor). The engine will never start like a stock GM ECM, but it ought to start cold as quickly as hot, right?

Thoughts anyone?
