Clutch replacement suggestions

[cop on my back]

Yup, need to do crank relearn, happened to me too.

I bought one of these and FORScan lite app. Hopefully this might do it?

Man get a better mech ....... the boy's NTS.

Lol, he said he had read some forums about the pedal issue and it was that cylinder that failed and not the clutch. So he figured he would change that out since it was easier to do than pulling the trans. He was wrong…lol

And I asked him about the crank relearn and he said he did it after He replaced the clutch. He said we could try It again in case it didn’t complete or somehow the process got corrupted.

Hope normally isn’t a viable decision, but, hopefully that new reader will shed some light on why the wrench is still on. Makes me paranoid to drive the car because I don’t want to screw anything else up.

And thanks to all who have given me advice and recommendations. I really appreciate it.

I’ve got a lightly used RST I just pulled from my car with flywheel. Shows zero wear. Pm if interested.

You won't do any damage with the wrench light. The crank relearn is pretty strange, you need to be at temp and hold the revs to like 4000 for a while. Mine was misfiring and throwing codes. I had my clutch replaced while on a road trip and had my tuner with me so I did the crank relearn myself and solved the problem.

Same here, my old school mechanic had no idea about the crank relearn. I did some research here and if fixed mine myself since I had an SCT tuner on hand.

I had a check engine light which was the first thing I noticed. On a longer drive it was actually misfiring and pulling power. Crank relearn fixed it.

I still can't understand how a clutch replacement could affect the crank trigger or what ever it is that goes wonky. I miss old school!

You mention that you have the ford performance power pack 2
That has the option of crank relearn in it

I think its an engine tuning thing? I hear you have to do that process if you lug the engine down with a blower on a pully too. Basically my guess is that If the engine is more or less free reving than the ECU expects, then the tune isn't quite dialed and may give a little too little or too much fuel for that moment, so you get misfires, and then relearning the crank recalibrates the ECU to how easily the crank spins.

The car doesn't know it needed a crank relearn, it just knows something isn't right which is causing misfires.

I never thought to try that.

It’s weight on the crank which changes a lot when the timing is so precise.

The crank relearn is for misfire detection. Manufacturing isn't perfect and anything that's bolted to the crankshaft has "highs and lows" so to speak. The computer is exceptionally accurate at detecting misfires. It does this by comparing each cylinder power stroke and seeing if there's a time difference which indicates a change in output. If the computer doesn't know the default profile of all of the rotating masses connected, it can't accurately determine when a misfire is occurring.

In Ford IDS it's called misfire monitor neutral profile correction, not crank relearn. That's just the shorthand people have been using.

Crazy. Makes sense though.

I will keep y’all up to date with how it is going.

And thanks for all the info. I had no clue that changing the clutch affected so much. Can never know too much.

I am also going to install a Barton hybrid 3 this weekend. Torn between body or trans mount. Anyone have any experience with this shifter? Didn’t find many threads on the forum about people’s mounting experiences with this shifter.
