I have not tried anything faster then 10.5 with 422 software, but if I am going to try it, I would do at least 1 setting lower from the 10.5 setup.

Speed Passion drivers from Europe has been testing the 422 software with 3.5-4T motor, however, we have yet to receive any recommanded setting for these motor use.

See Charlie-B 10.5 setup above and decrease a notch on 9, 12-15 items (don't forget to gear lower then 10.5)and temp motor every 5 laps or so.

Let us know your testing....good luck.
