AdvanceTrac engaging at high speed shifts

Hptuners doesn’t differentiate between at/sc and tc. If it cuts throttle due to either it just shows up as tc and doesn’t tell you why.

Those screenshots got me thinking. If you search pcmtec parameter list you find several parameters pertaining to yaw threshold. Who wants to test this?

If there's any way I can help let me know, but sounds like I'm tapped out here.

If you can repeat your issue and have pcmtec then you can test a change yourself.

I can do some testing with my can sniffer but I don't have PCMtec or a J2534 connector. It looks like there’s a yaw threshold and I see some CAN data that looks like it modulates the brakes and some torque value. There’s also some CAN data regarding oversteer, understeer, linear, non linear, exit oversteer, exit understeer scenarios. What happens during these? I’m not sure.

Unless there’s a way to add custom mapping for additional modules (abs), I don’t see how hp tuners could differentiate tc/abs.
