Eventually, I'll get a cheap laptop with coding ability so I can get useful info on the display while driving. I'm not a programmer, but i'll give it a try. I already tried to use the BC programming trick, but it reverts back to ambient temperature.

So in the meantime, I'll use my Torque Pro App to monitor realtime coolant temps (I should've kept some gauges from my racecar!). Oil temp, oil pressure, transmission temp would be nice to have displayed as well. I can't find any BMW-specific PIDs to add to my TP app, either.
