Basically there appears to be a FG build in the wild which what I would call a 'Police Special'. So we had an interesting ABS issue come up recently with two sperate cars. no abs faults but i cannot get the speedo to work. You'd also need to confirm there are no body wiring loom differences, brake master cylinder is the same etc.Īny feedback on the fix for this one? i have the same issue, fitted a turbo pcm to my n/a ba xr6 with abs but without traction control. licence the PCM & change the speed source setting to match the original PCM.there may still be other differences in the calibration that may cause problems I believe you'll have 3 options.I'd go with option 2 if you have the original PCM I wouldn't expect that the calibrations would be in any way compatible which rules FORScan out as an option for fixing your issue. The first is a 3 channel system for ABS equipped vehicles & a 4 channel system for ABS/TCS equipped vehicles.
You'll find the speed source setting is incorrect in the PCM for the vehicle.
