You can supposedly do the same in hpt in the scanner functions. Hopefully big d will get his sorted out without having to do it

Just did a quick Google search. It's in the scanner function but not while doing a scan.

I just got home and I’m dropping a log, afterwards I’ll wrap up the sheets I used to cover my dead plants with and then try this.

Yeah I think you have to rev to 5k or something.

Currently, my in gear and P/N fuel cutoff is 6,950, I think I'll drop it down a bit before I do this case relearn.

Dropped it to 6,500 and did a semi-slow neutral rev up till I felt the limiter kick on, then I let the RPM naturally fall and cycled the ignition which it told me to. I never got any indication that it completed the process or whatever but I guess I will log later and see if anything changed.

**Edit** Did a little more research and it clearly didn't work, it's supposed to set a 4k fuel cut when it's in test mode. Gonna try a couple more things such as holding the brake while doing it and not clicking the "OK" box. Seems people have all sorts of funky issues trying this.

Seems to me there was something about the parking brake. I have done a case relearn a few time with my tech2 and did fine.

I think its parking and foot brake needs to be pressed, I'm hoping it lets me do a relearn since HPT always thinks the truck is in 3rd gear and not park which was another requirement I saw.

Can you change that quickly?

No idea how to do that tbh.
