If you have a JDM GTR running a Cobb AP map, do NOT upgrade to the v9 TCM. HPCs in Japan are currently offering this upgrade to customers as an option - just say no thanks.

The new TCM is the one with the "smoother LC" etc, but it has an additional speed limiter that the current AP cannot delimit. Not worth it until there is a workaround for that...

This also likely means the Cobb AP on a newer JDM GTR (series 2) cannot delimit the car... but I don't know for sure.

I found this out the hard way DAMN!
