There is also no room for the reverse gear speed sensor so that would need to be relocated as well and a new trigger wheel made to emulate the pulses of the gear teeth.

I hadnt considered the calibration procedure, perhaps it could be skipped though. We planned to use the DCT controller to emulate the X/Y axis voltages for rev match, but so far have not bothered (revmatch isnt going to be able to hit target RPM before a preselected DCT shift, though it would probably be helpful when a downshift was not preselected), so I cant say if it would actually work or not.

What is the relationship of the reverse gear speed sensor? I dont know if I even realized there was one. I thought S-Mode was comparing engine speed from the crank trigger, to input shaft speed on the trans.
