Actually, it may be a bit of a change to the control board, as the wheels must be
independently driven. If using PWM to drive your motor controllers, you must use four separate PWM ports, not two with wye cables. For the record, 3946 used two-CIM drive trains for both 2013 Ultimate Ascent (the only time we seeded top 24 at Bayou regional) and 2015 Recycle Rush (the only time we were picked for eliminations -- and we put our alliance over the top to go to CMP).
