EFI conversio - TPS and the 3.2 Manifold
I am helping to install an EFI conversion to replace CIS on a 930. We are using the 3.2 manifold to help increase flow.
I know I have seen a TPS that is a direct fit for the WOT switch on the throttle body of the 3.2 manifold. I can not seem to find the part number or thread that had this information despite quite a bit of time in the archives. Please let me know if you have any suggestions or help.

I'm sure you're familiar with the DIY-EFI board, you can try there. Also I'd look for BMW information since the Motronic system is shared with many of the older BMW cars.

Yes, I am familiar with these forums. I seem to recall there was a Volvo part number that was a direct bolt on to the Carrera TB. Maybe I should look at doing the Ford V8 TB swap.
I agree that it will be a standard Bosch part.

Jamie,
I got this one from Geoffrey at Race Tech Engineering. CCW rotation, as I recall. PN M518-1 for CCW and M518-3 for CW rotation -- as seen from the shaft side of the TPS. I could not find a direct-bolt-on that was analog and not the three-position switch that was OEM on the 3.2. You will have to fabricate a mount to adapt it to the 3.2 throttle body. I made one from 3/8" phenolic as seen in the picture. JimS made one from aluminum as can be seen in his thread on EFI for a turbo. EFI and Data Aquisition Specialist - Above the Standards  Brian |

Call Jeff Gamroth @ Rothsport Racing. I think he has a switch and an adapter to make this work. His phone 503 885 9626 PDT.

Here's some good info on using a 993 sensor.

Oops. Forgot I was in search mode when I hit reply. Am looking for a TPS option that works for an SC?
