Does everything Slippery mentions.
Superchips added TPMS disable in a firmware update a few years ago... updating the device is pretty painful (or at-least it was last time I did it a couple of years ago, and I doubt the software has improved.), but does work.
I've had a few incompatibilities (most-likely due to the export.), but always solved by Superchips support. Which typically involves plugging the device into USB, sending 'calibration data' to Superchips via their rubbish/out-of-date software, and waiting a week or so for them to issue an update.
Dunno if the newer devices have better or worse compatibility though.
