Efi

I was wondering if anyone had ever added a TPS to the single throttle body used on a K Jetronic of is everyone was using the TPS emulator by using a vacuum connection to a Megasquirt?

I was using my stock throttle body on my 930, check here post #14:

Another EFI conversion

Guess same solution possible for any single TB...

As long as it has a D shaft and a mounting point you can make it work.
SDS sells a simple TPS to mount.
They have two models one CW the other CCW.
I changed TB's and the CCW I had was easy to drill through and carefully file it open and I just flipped it over for CW.

Not putting miles on your car is like not having sex with your girlfriend, so she'll be more desirable to her next boyfriend.

Mine did not had a D-shaft, but the TPS is available as early version incl. shaft:

TurboKraft Inc : Thottle Position Sensor Set - Early Models [930 606 113 TK] - $188.00

or the late version without shaft:

I used a 3.2L intake which has its own D shaft. A 3/8" spacer is required to move properly position the TPS. The TPS is the same one that SDF sells and the spacer is 3/8" phenolic shaped on a table saw. I patterned mine from Jim2, but he used aluminum for his spacer.

Yes that is the same one I have except mine is grey, I think the grey one is CCW and the black is CW.

But if you got the wrong one you can carefully cut a hole in the center of the circle and flip the TPS over to work the other direction.

Mark - I love it - I've had problems with the TPS on my TRW intakes (like the resistance dropping as you open the throttle, then finally increasing), and the official replacement (for a German Ford or some odd model) is a bit pricy. Looks like a guy can just get creative. The Electromotive programming will adjust to give a linear response by zeroing at closed and WOT, so the values maybe don't matter all that much.

Use a mid-90's BMW of any model except 318i.

I have a 95 325i one on my 3.2 TB.

Man, do you want some help making one of those out of Aluminum?

David: oh, to have received this gracious offer in 2011 when I made this! Thanks for the great offer, but this has been running quite well and shows no signs of deterioration. The phenolic is quite sturdy -- I was really surprised how hard it is and how tough it is on saw blades. In this application, it is not subject to bending stress or heat. Brian
