Reversing this stuff is a big pain in the back. I'm doing Ford (Mercury) dash display controller as my free time pet project and it's only by reverse engineering the protocol. I'm mimicking stock headunit and collect data from MS CAN. But need to admit, that there's lots of logic in the protocol, so can be reverse engineered with brains.
Some pics and text (sorry, Russian only for now)

- p1ne 9y agoThis controller operates when stock headunit is removed and can print out on the stock dash display (FDIM) the following info: - clock (can be taken from 2010+ GPSM module or from external RTC clock - DS3231 based) - tire pressure (from broadcasts 2010+ or from Ford TPMS protocol 2008+) - tire temp (from TPMS protocol) - RPM - engine temp - current speed units are configurable (12/24h clock, psi/kpa pressure, C/F temperature) Probably will share code and PCBs on github soon, now this thingy is under heavy test in my car and other cars of some enthusiastic guys There are plans to extend the device with CAN proxy to allow it to work together with stock headunit and also sit on both HS and MS can buses to get more data do display
