Hey Guys
Im tuning a track car which has had a Ls1 conversion, car has basic mods CAI, comp cam, custom exhaust.
The car cranks but wont fire, has spark, fuel pressure and injector pulse.
When logging found commanded AFR goes crazy, all the way down to 3.86 with injector pulse width going to 45ms.
This car has had numerous wiring issues, which we are sure we have sorted, just wondering if anyone has had similar problems?
What affects commanded AFR while cranking?
