My On Board Computer has been weird since I bought it. It always says -30C, and some other screwey things but won't let me change it or anything. Is there a way to reset the whole computer? Thanks.

If it's reading -30, the temp sensor is gone.
What year is your E30?
When you do your oil changes, if your SI board is working, you can reset the indicator lights using a paperclip. Search the web... there are instructions on how to do that.
The computer diagnostics except for late models with OBD 1 are rudimentary at best.Estoguy

is this a "6 button" or a "13 button" OBC?
I agree that the air temperature sensor is gone or disconnected if you're reading -30'.
Disconnecting the battery will reset the OBC. And then follow the procedure in the owner's manual exactly to set the time and date. It's pretty unforgiving if you miss a step.101
