Speedo/TPMS

Anyone know how to use the windows version of alpha obd to change the TPMs settings?

Follow the instructions exactly. I think I held the combination of buttons too long. I'd have to pull the instructions back out but it says something like hold them for two seconds and then release. If you go longer than the specified time you will get the errors. Good luck, this stuff always happens on the weekend.

Read somewhere that while the Procal could change the TPMS thresholds you still had to go to a dealer to officially reset and get the low pressure light turned off. Perhaps that was an older version and they’ve figure out a way around that now. Thoughts?

Depends on year. 19 and newer uses snap and no dealer visit necessary

I got through to AEV tech support and it was a pretty easy fix. User error on my part but all is well now. I haven't driven much but the speedo seems to be right on with 37's. I was about 7 mph off before. It will be nice to not only have the speedo correct but more importantly the odometer. You can also change the TPMS threshold and gear ratio with the pro-cal.

Hi Capital E. I got the same error 105 and a check engine light. What was your user error? Thanks

It's been a while but I think I held the buttons down for too long. Follow the instructions exactly and it will work.
