any new tps upgrades?
So my ongoing project has a bad s4 t2 tps. I am currently running a megasquirt ecu, so I am thinking about upgrading to a full range tps. I may get a used tps, I saw a new s5 t2 tps costing $300!
Has anyone retrofitted any other brands tps on the s4 throttle body yet? I wouldn't mind buying a new tps off another car that is cheaper and modifying my throttle body for it to fit.
I have a fd uim and throttle body sitting on the side. Its been a project I have not done yet because of I don't have a tps, I would need to remove my turbo to install my s5 lim, and I also need the elbow that comes off the throttle body. Are there any good retrofitted tps options available for the fd throttle body?
Again, I could buy a used tps from a forum member, but I would feel better with a new tps.

I fitted a haltech tps on both my s4 and fd throttle body.....its bolt on to the shaft just make a metall bracket to screw it onto. Took less then 1 hour to make it fit and costs very little. I think i used the clockwise version
Pic of the s4 install(prototype of bracket, i made one in aluminum later on that was polished but i lack pics of it

I did not modify either the shaft or tps.....it slide right on there, its a tight fit thou.
Edit: i did modify the tps on that pic because it turned the wrong way (haltech sent the wrong one). So i grinded of the plastic so i could mount it the other way around, thats why you can see the shaft thru the tps. DONT DO THIS hehe it will break very fast....dont ask how i know

I was going to have my buddy machine a cap that I could weld onto the thicker portion of the shaft, but it wasa little much work. So I'm going to just mil a little more of the portion of the flat part of the shaft so it pivots Better on the plastic tps.
I also found the bushings on my linkage had too much slop and my throttles weren't opening all the way. I added a washer to the 2 bottom throttles and they open together and all the way now. Maybe I'll take some pictures and post

well my thought is to make a TPS work without any modification, but to ditch the standard narrowband and use a more common alternative TPS mounted on a bracket.
rather surprised no one has really gone that route, since the standard FC TPS will all be dead rather soon and their cost is rather rediculous.

I'll see if I can take some pictures and post on my tps upgrade. It won't be something everyone will want to do, but give people ideas on their own projects
