I have a Raptor shiftlight that has been working perfectily for me since I bought it. Recently it's been acting funny. As it approaches the programed turn-on RPM is starts to flicker eradically (in no particular pattern). The light is set at 5700 RPM and will start to flicker around 4500. Once it hits 5700 it will stay on like it's supposed to.
I haven't done anything to the car, the wiring is still solid.
Any ideas??
Thanks
