SBS think we had this discussion in the past but does your advance-track go "off "when exceeding 100+ ? Z

Hmmmm it does I have not noticed it... I have not really exceeded 100mph... that's mandatory jail time if caught where I live.. PLUS an additional day in the clink for every mph over on top of how the judge is feeling that day!

I need to get to MIR or Colonial Beach...

Sounds like the AWD is working as it should.  Track prep could also be part of the problem.  At my tracks, sometimes there is some dampness at the starting line from guys going through the water box or even from dripping A/Cs.  The officials try to keep it clean and dry but they don't always do a great job.

I was suggesting a 1/4 Track!!!

Here's the previous discussion on the advance track system.  Z

I would focus and check for any Bent rims alignment,proper wheel balanced checking that sufficient tread remains,that they are inflated to specification and that their circumferences are within 1/2"of one another and replace tires as needed and that alone will cause an ABS/ADV TRAC FAULT AND Will SET OFF A DTC.


If you can verify that chassis modifications and the tires aren’t at fault monitor the steering angle PID’S in the PSCM and SCCM, the accelerometer PID’S in the ABS module (YAW, LAT, LONG, ROLL) and the WSS PID’S in the ABS module and note for any false readings when this concern occurs. Note it is normal for the steering angle PID’S to not read 0° with the steering wheel straight ahead due to the way that this position is recalculated on each key cycle. Also note that the accelerometer PID’S will need to be monitored at a standstill immediately after this concern occurs and they should read close to or at 0 with minimal fluctuation (note for difference in reading when this concern is not occurring vs. is occurring). If a faulted steering angle input is found, and depending on where the false input is originating, replace the affected component as needed (EPAS steering gear or SCCM w/ steering angle sensor). If a false accelerometer input is found suspect the RCM is at fault. If a false WSS input is found suspect a WSS/tone ring/wheel bearing issue and repair accordingly. Z

I asked the guys after I spun really bad if they were prepping the track... they said of course...

Here is a decent video of the track to give you an idea of its ummmmm quality...
