I'm having issues while footbraking and the Grid not recognizing it's not in first. If I use transbrake & delay box the car shifts itself with no problems using the +12V on blue wire. But if the delay box is out of the car and I apply +12V to the wire while footbraking it's only in 1st gear until I let go of +12V supply. I have changed RPM to activate and still nothing. Any help would be helpful.
