Great Product - Please read if using on GTR

This is a great product. Just by itself it is easily the best thing and easiest to use for improving laptimes. Great customer service as well when I was at the track and needed help.

GTR Owners - I spoke with Harry, the GTR ecu is a bit wonky in how it works. So the OBD2 functions wont read proper values. He expects this to be fixed by version 19.1 which is expected no earlier than middle of this year. Just an FYI because I couldnt find anything on the forums about it.
