981 GT4, upgraded gears 1-5 with a set of shorter gears from Guard. Rev matching of course now doesn’t always work, maybe 50/50 … does anyone know if that function can be reprogrammed to match my new gear ratios? I have access to both Cobb AP and PIWIS3.

did everything get plugged in and there's not a bad sensor? I've seen that auto blip works perfectly fine with other gearsets. I'm thinking you've got an electronic issue because I used to club race bikes and my translogic auto blip on my R6 started acting weird and then my throttle died, had a bad translogic ecu and once I replaced it the bike was back to 100% perfect with the auto blip

Check the crankshaft sensor?. Everything ive read here says that the reva matching works on gear set changes. Also ask Guard directly.

I would ask Guard but it seems like rev matching works as intended.

What gears did you do? This is the first time I’ve seen 1st replaced I believe.

I had gears 1-4 replaced with Guards and rev matching still works fine replacing 1st gear dropped it only 2mph

well I guess when I get to this mod I'll just do 2-5. Seems like that would be better to spend the money on 5th rather than 1st. almost tempted to just order all the parts and do the build when the car is paid off.
