So, this started happening yesterday morning after I changed tire size with Forscan in the BCM. I accidentally rebooted the BCM instead of relearning the PCM. I tried to get back in this morning to relearn the PCM, and now my license is expired and my Forscan license doesn't seem to want to upgrade to extended after going through the process like usual.
Anyway, here's the issue. I'll be driving and upshifting and the RPM's kind of bounce around a little, but on full release of the clutch, my car will jump forward a little. I can't be sure if the RPM's go up a little, but it looks like they may. It's also happening when I downshift. It's making it nearly impossible to have a smooth shift. This is with Rev Matching turned on. I've tried reloading my tune, and it didn't change anything. If I turn off Rev Matching, it's fine. Currently have a P160A code, but probably because I haven't done a relearn on the PCM.
Another issue I have is since I had my RST clutch installed my RPM's will bounce around on downshifts with Rev Matching on. I've just lived with it for the last year. I saw a post about someone else having a similar issue but it doesn't look like it was fixed, or they never replied again with an update.
I'll try and get a video after work if possible.
