Alright I have searched through lots of threads and still havent come up with an answer so here it goes.......................... I am trying to hook up a S4 Jspec in my 88 and noticed that the motor I got uses dual TPS. can I run this, is there a way to run this or do I need to swap it out for the singel TPS. If I have to swap it out any one wanna trade?!? lol ANY help would be greatly appreciated, im so sick of working on this car im about to take it to a shop and say "go nuts!" GTU to TII swaps suckkkk.....oh yeah I am using a TII wire harnes. thanks



Micheal

the dual tps's are a series 5 thing, you can put your single tps on there i think



mike

yeah, you have a Series 5 engine! Cool beans you get higher compression and lighter rotors out of the deal! I don't think you will need to swap the T.P.S. as long as you have a S5 ecu!

Good luck dude.

He would need the ecu,engine and dash harness to use it on a S4 car.Just easier to use the series 4 intakes.

ok just to clear this up im not a moron and I know what im talking about.........................IT IS A S4 MOTOR......s4omp, s4 turbo, s4injectors yada yada yada it just has dual TPS which I dont know what to do with?!?!? Has any one else encountered this on a jspec before? sorry to sound like an ass but I know the difference between S4 and S5 and help would be appreciated

Heres your answer.

hmm, maybe it has an s5 t body? so put your t body on there and call it a day

I saw his engine firsthand and was a little confused also. Definitely mech. OMP & S4 turbo. The first thing that came to mind was that it was out of one of those mid-88 cars that had high impedance injectors(I think that's what he's got, they were purple topped if I remember correctly). Did those cars also have the dual-range sensors?



I know you guys say the easy fix is to put an S4 TPS on and move on........., but aren't the TBs different enough in how they drive their respective TPSs to prevent this? It seems to me, w/o another TB, his only option is to rewire one of the two that are there. Or both somehow? It's a jspec going in an NA btw.



Is there a way he can use both to his advantage? Thinking about the whole throttle position problem with a Super AFC, even though I think he's got an Fcon which I don't know much about but would think it would need that input too.

locate a S4 TB! that's what i'm gonna do when i get my S5 engine and i'm also gonna swap the front cover.
