Question Re: Automatic shifting software

How does one figure out at what RPM/velocity/joystick position shifting is ideal? (We are using four small CIMs and Dewault transmissions.)

And how should the lookup table be structured? Why should it be joystick (throttle) position vs. speed? In a manual shifting car you get back RPM (tachometer) vs. speed (speedometer) and shift based on that (I think...). So shouldn't you shift up when your motors reach a certain RPM, while lowering power to the motors to maintain constant speed? That way you can continue going faster.

Thanks in advance,
Robinson
