I have decided to go a different route then most and install two indivual throttle bodies (ITBs) instead of a single throttle body and plenum type system. So far everything is working great based on Speed Density (Maifold pressure reading) which many thought would not be possible. I also have a more agressive cam with no overlap which probably makes the situation easier (278 duration, .288" lift). More information to come as I install EDIS spark control. Until then I wont be able to give a full review.

Sensor calibration

The temperature sensors were ordered from my local independent BMW parts dealer. OEM part number 62110788115. They are just the simple one wire-hookup type, the housing is the ground. They were very easy to calibrate actually. A lot easier than I thought. Just get yourself a known working thermometer and freeze and boil some water measuring the Ohm's at 3 three known intervals. Here are my results:

F - Ohms
44 - 1.300
80 - 0.568
185 - 0.73

I then plugged them into my MegaSquirt and they all checked out. That simple.
