For some reason, they switch the controls in the OEM cars. If you REALLY want to use the OEM cars with the 4-band controller, you need to swap two wires on the board in the car. I don’t know if they are labeled the same as the real Bits, but if they are, you want to swap the ones labeled “F” and “B”. If they are different, then just don’t swap the red, black, or two hair-like wires. The other two will be the forward/reverse control wires.
Of course, I’d just use the controller that came with the car since you get better range with it anyway.
