hey guys got some problem and i been pulling my hair out
car 98 t/a 5.3 turbo 76mm 224/224 cam 80lbs injectors
1 car takes a long time to crank and fire. maybe 3-5 seconds! i mess with cranking VE but no luck and tried changing prime time still no change
2 when under boost commanded fuel 11.2 and i got 12.6
thanks in advanced

 

Two quick things, add some fuel to the 400 rpm section in the primary VE, and see if you can verify how long it actually takes for the car to build 60 psi at the rail. The issue may not be in the tune itself. For the PE, it sounds like youre not going into BE only staying in PE but the settings look correct.

 

See if this is any better on startup. I changed the whole VE so if it starts better be sure watch your wideband.

 

hey Lorenz
i tried out your tune that u made car start up right on the dot but just little rich 12.1 to 11.9 im gonna play with min pulse and see if that change
thank you Lorenz

 

No problem.

This should be a little better, what's your fuel pressure set at?

 

hey Lorenz my fuel sit at 45psi i tried the file u made shes idle at 11.7 and i try to lower transient no change still same
