Hello! Took my street car to the track the other day and there’s an issue with rev matching I cant see a reason/solution for within the parameters in the software - it often would only rev match on only 1 downshift (4-3 shift) then ignore the following shift (3-2) - I know it has been ‘fixed’ a long time ago, and I’ve defiantly had it work correctly and rev match on multiple downshifts through the gears - even on the same day - but its either not consistently doing it - or is there maybe an issue with downshifts in quick succession?
Emu black V3.056 - conventional H pattern box - clutch and brake pedals connected to switch inputs on the ecu
Another issue I have is that sometimes when the clutch switch input activates the brake switch input activates for a split second (1 frame in the log) which occasionally activates rev matching - so this can happen when I’m up shifting and pressing the clutch and the brake input activates for a split second - this SHOULDN’T be an issue because the brake input doesn’t remain on therefore the rev match SHOULD be cancelled when the brake input is no longer active - but this is not the case - the rev match runs for the “Max blip duration” or until the clutch switch input is no longer active even while the brake switch input in inactive. I think i have found a backwards solution to this issue by rather than activating Rev. matching using clutch switch I can activate with a function using brake and clutch switch input operators though seems like something that could be rectified in the software
Attached is a log, with 4 events compiled into 1 short log -1st event is false activation without brake switch input, 2nd, 3rd and 4th event are examples of failure to activate on subsequent downshifts.
Thanks for any help/feedback

Another side note; a “throttle blip ref level” vs “Rev. match target RPM” table would also greatly improve the rev matching - in my case 20%TPS is far to aggressive for street driving and matching to ~3000rpm where >14% seems good - but to match to ~6000rpm i need >20%TPS
