Gear shift speed matching setup.

[oversteer]

Hello

 I have a R32Gtr with an OS88(proper gear pos pot fitted and Holinger strain guage knob), I've been using the flat shift for a while in a basic set-up which has been functioning fairly well on 500Hp. Now car has been tuned on E85 and 750Hp the flatshift needs to be better.

 I have enabled shaft speed matching and populated gear ratio tables etc but now with driven up shift there is very little cut, I can feel a little bit of somthing but the dogs do not get unloaded.

Logs show some large RPM targets so I have somthing configured wrong ! When I set the RPM target adjust down to numbers near zero the target nunbers are more sane and target error is small, but I'm still not getting power reduction/cut !

Is there a way of logging the actual "Cut severity" figure ? Its still as before set in the 90's in low gears...

Your gear ratios are wrong.  They should have smaller values for higher gears.

"% Ignition Cut".

RPM Target and cut should look something like below.  The RPM should just kiss the target towards the end of the shift.

Start with the dog unload at 100% for 20ms.
