A Porsche 944 Turbo TPS looks like a bolt-on proposition to replace the GTV6 TPS. It’s kinda pricey ($100) - maybe because it’s made for a Turbo car and therefore better sealed, or maybe just because all Por$che parts seem to cost a fortune
Does anyone have a Bosch part number that is also a bolt-on? I hear the Volvo 850 TPS works. I just want to have this signal for data logging since I'm using the MAP signal, but maybe will want to experiment with the TPS signal in the future.

Michael,
Did you ever buy and use a 944 TPS? does it work correctly with the MS?

Hi Andrew:

I have bought one, and can confirm that it does fit, but I've not tested it with MS yet. My current project is on hold until I can tune it better. Actually, I'm planning on building a V3.0 Main Board to replace my current implementation.

Cheers,

Mike,

What's the advantage of V3 vs. V2.2? Maybe you can sell your board to me? Both can do spark control right?

I recently found out that a TPS from a Delta Integrale fits a TS TB perfectly, not sure if it helps you at all but it maybe someone can be helped by it.

Is the model you used a 944 Turbo or 944 ? I am looking for a three wire TPS that will give actual throttle movement not on and off like the stock switch.

I think so yes. The 3.0 board is much more robust - a good write up on it here:

I like the bit about better support for MS-II and MSnSE - with a direct ignition coil driver built into the board. Its also apparently more resistant to the dreaded tach falsing phenomenon that I fought so long.

Once I have the replacement built, I'd consider selling my 2.2 board. However, its been soldered and de-soldered on quite a bit so I'm not so sure you'd want it

The TPS is 0 280 120 400 - for a turbo.

Cheers,

FYI, I've got TPSs from a Volvo 850 (950?) turbo and an Alfa 155. Neither are bolt-on additons to the GTV6/Milano throttle body.

Michael,

I'm looking for a 3-wire TPS (true potentiometer) for my verde with GoTech. The Bosch parts number you listed above seems to have a 6-pin connector, and not a 3-pin connector - pic
From this site

Do you use the 6-pin TPS for your MS? Do you know how to wire it for 3-wire?

Andrew told me he is trying 0 280 120 308 instead - pic. Unfortunately it doesn't show the pins, but from the size you can tell it must be about 3 pins.

Edit: But from the Hugo parts list 0 280 120 308 appears to be a TPS SWITCH and NOT a TPS POTENTIOMETER - check out page 70 for symbol description and 71 for Bosch parts number 0 280 120 308. Note that the verde has a 0 280 120 304, if I remember correctly.

Jes,

Autronic uses 3 pin TPS. I'll check the Bosch part number for it today.

Perfect Zamani!

Jes

you can use the 0280122001...but it's not a bold-on solution....you con found it on the 155 V6, or 164 QV...

The idea was to find a bolt-on true potentiometer TPS with 3-pin connector. Lets see what Zamani turns up. Zamani? Worst case, the 944 Turbo is a straight bolt on, and then it's just a matter of figuring out which of the 6 pins to use.

Jes

Part no. is 0280 122 004

Zamani, is that a bolt-on to the milano throttle body? My reason for asking is that it maps to the same Huco part (138601) as the one suggested by Enzo, which he says is not a bolt-on... You can see the Huco part on page 76 of the catalog referred a few posts up.
