motor timing 0
This setup use in mmh 8.5t hi-torque version, the motor temp looks allright is 65-70 degrees celsius,
if change turbo boost 7>10, speed have more better Performance, but temp up to 80+ in 4minute, and very fast speed on keep 2-3 minute, after 2-3 minute later speed down, look same turbo boost=7's speed, look feel no trubo boost in final speed, but timing boost looks no probelm.
