I had this happen to me. Until I had a chance to fix it, I figured the sensor was probably in circuit with the traction control. If the car thinks that you're on the brakes for a long time and not slowing down, I figured it might kill signal to the throttle body.
I held down the traction...
When installing the Procharger, isn't part of the install messing with the crank sensor? Is it possible that something may have gone wrong with that and that that's why it isn't able to be calibrated? Definitely check with your tuner to find out if they disabled the crank relearn in any way. At...
Oh man that's great! I'm glad that's all it took. I wish I had known this back when I thought it was my clutch causing hesitation. The dealership made $1600 off of me because of ignorance. Haha never again. Live and learn.
A crank relearn is just a way of recalibrating your crank position sensor. If your crank sensor needs calibrated, it can effect spark and fuel delivery. The process involves getting the car up to temp, then revving the engine and letting it idle. NGauge has a crank relearn, but I'm not familiar...
Oh no. Yeah the Power Packs don't support E85. My car has gone through stages of different mods over the years. But I did have that problem after installing the Power Pack and a crank relearn fixed it. Later on, I went full bolt on and now have a flex tune and a race tune from Lund. Anytime I...
I'm not trying to be insulting or anything with this question, but did you have the car run and get up to normal temperature before doing the crank relearn?
Anytime you load a new tune or even use different fuel, a crank relearn should be done. Please let me know if it fixes the problem. I'm curious to know how it turns out. Good luck. Can really be a pain in the ass when the pony won't run the way you want.
I had this problem at one point. It was when I was running the Stage 2 Power pack from Ford with the GT350 throttle body. It ended up being just a crank relearn that needed to be done. Anytime I switch fuels (pump gas or E85) I do a crank relearn. Any changes to my car; I do a crank relearn...
