Rev hang question

[sms2022]

Tire size adjustment in bcm on forscan and pcm parameter relearn, plus resetting the KAM and driving for 100 miles or so while shifting as fast as possible has fixed 99% of it for me.

So which procedures did you use on FORScan exactly for both pcm relearn and KAM? I thought I did this last week but making sure I didn’t miss something.

Change setting in bcm. Then go back to the programming page and run the pcm relearn process. Then go to the tab above it, service procedures I think it’s called, and clear pcm adaptive learning. There’s also an option in that tab to halt transmission learning that I don’t think will do anything since we don’t have a tcm but you could try it

Awesome thanks. I’ll give it a shot. Thank ya

Ok gentlemen. I have the fix for this 100%. Switch on launch control after doing the tire size procedure above.

I can shift as fast as i want now, no rev hang.

Are you running stock size tires just a different brand that are slightly larger? Did this fix the issue for good?

I sold the car but had larger tires. The size is in my signature. It did fix it for good.
