Running the same motor 4.5t X12 I have to run 1 pinion lower otherwise the motor gets to hot and the car is still accelerating at the end of the straight!

My questions are:
1) Can I use my SP usb programming box with the SP 1.35 software to program the esc ie 205, 422, 518 etc and is this as good or the same as the HW software?

2) Our BRCA National series runs at very large asphalt tracks with straights up to 70 meters long, what firmware, settings & gearing should I be running with a 4.5t X12 motor.

3) I tried running with the SP 422 firmware with the 4.5t X12 on default settings and the + & - wires came unsoldered from the esc within 2 laps.
(but it was very fast)

Sorry if I have missed any previous posts I could not seem to find any.
