So far I think I'm just keeping the ABS and EPS, but wondering if anyone has logged CAN and determined if the TPMS data stream carries actual tire pressures. On a lot of BMWs, the iDrive display doesn't let you see actual pressures, only "ok" or "not ok", but the CAN stream actually transmits the 4 tires pressures when active, but only at 5 sec transmit rate. This may still be useful enough for data logging when overlaid with other data.
Anyone have any idea?

unfortunately not for the actual values of pressure/temp. only for the light in the dash
