Cluster from BMW E36 work fine with 2 RevBurners (one for speed and one for RPM) and ProShift for bulb (replace with led).You can see my post SymProjects Forum http://www.symprojects.com/forum/index.php?topic=38.0
But for BMW E30 I can`t find cluster pinouts and don`t know if it is compatible with RevBurner.
I think this is Thrustmaster T500 RS thread and it would be nice to write bad and good things about T500 RS,put some new pictures and not comparable with other wheels (there is a second thread for that).
Only bad thing is fan but I replace with new one and put another one in case that cool the PBC board
To another do not have any criticis.
I think couple of holes in the front grill (2x10mm) to allow for air intake is not enough.
See picture below and if you want drill hole in the middle of front grill
Hi
I have used this configuration because the "big" fan (Club) push "cold" air in case over PBC and both small fan with heatsink push air through the holes in the engine.
After few hours drive top of case is still cold
EDIT:
3v is enough because air is passing through the case better then without fan
In 5 years I change two G25.First die about three years ago (both motors die) second still working but I sell it about 4 month ago and buy T 500RS.For now only hot recommendation
