ok, I have an e6k and its already wired for an s5 TPS. I have an s4 turbo Throttle body. How can I mount the two together?

Or will I have to buy an s5 throttle body? Also if I do do that will it fit with all my s4 stuff? (tb elbow and UIM, obviously not the OMP)

I've searched all over and I cannot find any info on this subject thats reliable. Thanks

 

Yes you need an S5 TII TB with TPS

Will bolt right up except the OMP mechanical rod

I have one with TPS if you need it..

 

WRONG
With a little modification, you CAN use an S4 STOCK TPS and OMP with a haltech e6k. I know, I did it, and it works perfect. I wanted to do an official write up and take better pics, but I will jump the gun.


See that little crescent shaped cam against the TPS plunger? That's the trick. As it rotates, it pulls away from the plunger, but very gradually. the stock sensor is operated by a little lever that lets go of the plunger wayyyyy before full throttle. That's why the stock won't work without a little modification. I drilled a new area on the S4 TPS mounting bracket so I could move the position, and keep it in line with the crescent cam I mounted on the shaft. Again, notice I have the OMP connected.

EDIT
And before all this, I had made a simple OMP lever by bending some little metal pieces and mounting them on the shaft using the E6K tps. So with a little patience and tinkering, you can make it work either way.

 

ohhhhhh, thats really cool. THANKS BEEFHOLE! I'm gonna go try that and see what happens. even cooler is that I'll be able to keep the mechanical OMP.

 

actually, could you draw a picture of the shape of the cam you made? I'm looking at the TB and wondering exactly how to make a cam that will fit, not slide around, and open the TPS correctly. Thanks.

 

one last thing, how did you wire the TPS to the haltech harness?

 

ok, so I made a sweet custom cam out of 2 washers to make the s4 narrow range TPS into a full range TPS. Then i hooked up the haltech to it, hopefully my cam is good enough, if not i'll just need to get an s5 throttle body, so not a huge deal i suppose. here's the wire connections if anybody's interested:

Haltech --- s4 TPS
black --- black/red --- ground
white --- green/red --- signal
orange --- orange --- power
