need to know what is your engine compression
what is your bore Size
Crank Size
Piston +10 or -10 whatever
your head what is it
72cc 70cc 68cc
when you start does it start normal or not ?
do you have a scanner log ?
after i have all of these answer i will download your file and give u a hand
good luck
LSX 454:
11:1 Compression
Bore is 4.185 x stroke 4.125
Pistons are stock size
Crank is GM p/n: 19170391
Combustion chamber on heads : 70cc
2.20 intake / 1.61 exhaust
Cam is 0.635 intake / 0.635 exhaust
236deg intake duration / 246deg exhaust duration
The truck starts normal when cold, but when it warms up you have to give it throttle to get it to run, and then it will find idle and be fine. But any slight throttle when its warm and it will begin to surge, sometimes stalling.
Hope that helps!! and send me a config file if there are sertain PID's u want to see on logs. Im still very new at this. Thanks alot!
Here is my truck.
ETC Area Scalar needs to be raised to around 7300
PE Enable TPS is too high.
I'd zero out PE Delay RPM.
Why is your Stoich value set at 14.97? and I hope you're not tuning this thing by adjusting your PE table.
this is a file on your file
you can compare what i have done
if this one didnt workout
shot me with your Stock file car
by the way ,, you need bigger fuel injectors
better fuel pump
i dont think the silverado fuel pump will handle this power
adjust your windeband so we can read
good luck
