Mountain GT

That's what I'm trying to find out, if my ECU would have had to have been factory programmed to accept the downshifts and do auto blip. If that's the case, then that brings up the question of how can an aftermarket QS work by hooking a wire to your coil for up shifts and a wire to your potentiometer for downshifts? Edit: I just remembered I believe they have to have a piggyback circuit board on the aftermarket downshifter. Correct?

I haven't been able to find any info on this at all. I'm trying to find out if I can replace my 2020 GT quick shifter with one for new model MT09 or Tracer 9. David at Vcyclenut would only say he doesn't mess with factory quick shifters, tells me he don't know, and says I definitely would not have auto blipper for downshifts. But that is what I want and by all reports the new quick shifter is buttery smooth up and down. I'm wondering if the new model QS would be a plug-and-play on mine or if it would just need one extra wire run somewhere for the auto blip, or if it just isn't going to work. I'm not looking to buy an aftermarket unit when I can get the new factory unit for $177 on motorsport. Any knowledgeable help would be appreciated.
