Ba Falcon manual conversion
Converted a na ba xr6 to manual from a 4 speed auto. Sent the pcm away to get a manual tune done on it. Received it back and it started and ran ok but had no speedo and the tacho acted like it was still an auto. Bought a manual pcm and programmed pats with forscan. Tacho now ok but still no speedo. No faults exist when scanned with forscan on either pcm. Can log wheel speeds so nothing wrong there. Anyone have any ideas? Would someone be willing to have a look the pcms if i send them to u to see if vss is set to abs or gearbox. Can hp tuner change that setting? Thanks all.

Advanced Tuner
it will be the speed source setting. the choices are abs, tcs (cars fitted with traction control but is still run through the abs module) and oss (output shaft speed - the sensor on the back of the box.
this can easily be changed in hp tuners, it just has to match what the car has.
did you end up getting this sorted? where are you located?
