Rpm's climbing when put into gear
Posted: 2023 Nov 11, 22:32
I am attaching my data log and tune for reference. The truck idles perfect "Blip the throttle rpms come down smoothly" and also drives down the street if you got a clear shot ahead...
Issue is...When I put the vehicle into gear the RPMs shoot up and the truck wants to take off immediately. If I let it accelerate without fighting it the truck will climb up to around 8mph then the rpms decay. The truck will repeatedly do this when trying to sit at a complete stop. I have tried everything to my knowledge of a 2 week binge on Decipha's Write up's, tweaking Dashpot Tables to no avail.
MAF curve is from the flow sheet provided with MAF (Added +5% @ Idle)
Injector Slopes are skewed to 39.50 Fuel Pressure (did my best)
I appreciate anyone curious enough of look into this.
Using Binary Editor for tuning/ Do I make the leap to TunerPro?
