I just installed brand new Biondo electric shifter with a Shiftnoid solenoid mounted to the shifter and a Biondo RPM-1 digital shift timer. Everything works perfect on jackstands. However, this weekend when at the track it somehow was shifting to 2nd immediately when I left the line! I'm wondering if there is some kind of interference going on with the transbrake, nitrouse system, etc... I have my system wired so that the WOT switch is killed while on the transbrake button and then activated as soon as the button is released. At the line the transbrake works so I know the shifter and trans is in low but as soon as it launches its mysteriously in high gear and makes a high gear only pass. I cannot duplicate this problem while in the shop though. I can activate my nitrous system and activate the WOT switch while on the button. Release button and I hear the nitrous solenoids click but shifter doesn't shift
Anybody got any clue what might be going on??????? Any help is greatly appreciated. Thanks in advance.....
