Alright....made some good progress.

Got the traction control working, NO codes, e-fans working. Just need to wire up cruise control!! So basically now its a factory-swap.

Couple questions still...

The 128k pulses-per-mile output on the ECM is still off...so after a mile or so of driving, the ABS module freaks out because the front wheel speed sensor signals are greater than 10% off from the rear wheel speed sensor signal. So basically we're cruising down the road and the front WSS is reading 25mph and the rear wheel speed sensor is reading 17mph. Or something like that.

The E67 has a whole crapton of tables in the speedometer segment... H0102, etc. Yet I cant figure out what the hell they do. Some of them seem to change the 4k pulses-per-mile output to correct the speedometer.........but none seem to have any effect on the 128k PPM output....which is the one that goes OUT to the ABS module....which is the one we need to fix.

Any ideas? Or better descriptions of how the speedometer and 4k PPM and 128k PPM outputs work on the E67 with a TBSS calibration in it????

Like H0135... "factor??"

thanks
