throttle body swap
 

Anyone know what would be involved in using the 94 throttle body w/ all its goodness (tps) w/ a 90-93 mspnp. I have a 94 engine in my car presently and would like to use the 94 t-body if it wouldn't be to much extra wiring to make it work w/ the mspnp. thanks!

Not difficult. You should read the MSPNP manual, as it will describe exactly what you'd have to do. It even tells you how to determine which wire is which on the variable TPS.

actually, he wants to swap the whole t-body, not just the tps. that's more work than it's worth.

just swap the tps sensor over to the 1.6 t-body. much easier.

Sorry, my fault. Somebody here knows the details of swapping the sensor only...TurboTim I think?

yeah I bought his converted t-body from him, actually. but don't know WTH I did with it. :doh:

just like that? it just bolts right up? I can take the 1.8 tps and it will work fine on my 1.6 tb?

nope you're going to have to finger it out. but it's much easier to swap the tps over than to swap whole t-bodies.

or search for Atl's BMW tps recommendation that's a bolt on affair.

Ben, im gonna politely disagree with you and pull out the flag :bsflag:

Unless I am missing something, if his motor is a 94(1.8), and his throttle body is a 94(1.8), that throttle body should bolt right up to his intake manifold, and the only thing he should have to figure out is a couple wires.

thats what i was thinking and hoping that it's just a couple wires that would be nice, however i dont think that be the case it looks like i need to go in and play w/ the board inside the mspnp and follow the directions on the mspnp site? is this correct? are the directions on the site for any pontimeter based tps and also is that what the 94 tps is?:confused:

A variable TPS as far as I understand always has a ground, a 12v/5v ref, and an output voltage (and a throttle closed switch on 1.6 tbs and likely 1.8 as well). I would expect that connecting the correct wires and tuning the tps (getting closed and open ADC) it will work in the same way as the 1.6auto tps.

Going back and reading the OP, I remember why I made my first response in the first place. It's in the manual, and shouldn't be difficult to open the pnp box and take off the resistors/add jumpers. Especially now that they clarified the manual after my debacle ;)

yeah, uhm he says 90-93 mspnp, so I assumed he had a 1.6. if he has a 1.8 swap in his 90-93 car, that's fine, but that's the kind of shit that the OP needs to state clearly.

Hmmm, Ben...perhaps it is us that need to read more clearly :cool:

haha
OK, I'm a dildo. Yeah man, bolt that muther up. Wiring's in the manual. Plumbing should be easy enough since you've got the 1.8. You'll want to start with the idle control and closed loop idle control settings from the 94-95 mspnp.

Sorry I missed that originally, would have saved a bunch of stupid posts.

Uhh guys from what i read the guy has a 1.8 and is wondering how to hook up the variable tps to his 90-93 mspnp. The link you gave him shows how to do that though. I dunno where you guys are getting that he wants to swap a 18. tps onto a 1.6? Well damn i gues i need to read all of it before i post next time.

i even wrote those posts high, and i thought they made sense hehe :gay:

It is a classic post after my format. No worries they will learn. ;)
