tps
 

I has a 9093MSPNP modified by DIY for VTPS
Found an OEM male connector at the junk and wired it to a BMW TPS.
Used the 3 shielded wires only

BLK +5 V
BRWN Grnd
YELLOW Signal

Wanted to know if this looks correct before i hook it up this weekend

TIA

is there a "how-to" on modifying the 9093 for variable tps? I want to send my car to the dyno this weekend, but would really like to hook up the tps before it goes.

Is it ok to convert to TPS later, or will that require more tuning? I'd like to pay to tune it once, and be done with it...set it and forget it.

TPS is only good for boost duty, over-run(not even that needed) and acceleration enrichment.

I dont think anything else uses TPS.

Shockingly, DIY chose to hide this information from the public by printing it right in the MSPNP manual. Specifically, it's in Section Five: Modifying your MSPNP.

As Sam said, assuming you run in speed-densnity mode, the TPS does not influence the VE calculation except during TPSaccel. Since you're doing your tuning steady-state on a dyno, accel should not come into play.



SideDraft,

I'm away from home this week and don't have access to my good wiring diagrams, but it's easy enough to figure out whether the TPS is wired properly- just stick it on the car and observe the TPS value of the MS by looking at the RealTime Display window in megatune. Does it go up when you press the pedal, and down when you release it? (Don't forget that you need to run the TPS Calibration wizard.)

for 90-93 it is supposed to fix the idle droop/dieing issues as per this...so it is most definitely not useless.

how dare they hide that shit. I've never soldered a board before...is this something I should consider researching and doing...or just ship it to DIY?

I don't have a lot of time, so I was just going to let BEGi tune it on their standard dyno. Is this a mistake? I could take it to Tuning Concepts for the same amount of money, but then I'd have to be there to work the software.

Surely there must be someone in the greater Dallas - Ft. Worth area who knows how to solder. Might call Bell and see if someone there is able to do the mod. This really is very basic Electronics 101 level stuff.

I'm in Austin now, and the last thing I need to do is fuck up on my work, and be stuck down here with a car I must get towed back to dallas.

Man up, you can do it. Get a soldering iron, some desoldering braid and some solder, find some junk computer parts and practice for 5 minutes, you'll get the hang of it real quick.

Its removing 2 resistors and connecting 2 wires.

By Calibration Wizard you mean, Megatune>Tools>CalibrateTPS>Get Current?

Should closed throttle read "0" or does it need to have a minimal value?

launch control works better :eek5:

Can anybody share VTPS part numbers or model vehicle that I can use the VTPS from ?

Thanks

The easiest would be from a '90-'93 automatic Miata, or any other B6 car (Escort / Probe, 323, etc) that used the same device.

Mine came from a B18C Honda. It required some physical modification to fit.

This would be easy.

Gentlemen;

Thank you both very much. I am on my way :)

where can I get some gay-little female connectors for the electrical connections for this shit? 99 tps and 1.6 plugs don't go together, like interracial marriage.

Try Radio Shit :)

They will first try to sell you a cell phone ;)

I failed at radio shack this morning. In for more, repeated failure. I need to just go to a junkyard and chop one off the harness.

yes, and many cars share the connector.

I'd love for some examples because I'm in the dark on this shit and I'd prefer to not take the t-body off to check fitment at the junkyard.

Not sure what you are trying to do.... Are you trying to find like a spade type connector so you can plug into the stock TPS switch harness so you won't need to cut it ?

I prefer the latter, but am ready to go with the previous.

I just went to look at the plug going to my "regular" TPS - if you want to save it without cutting you may be able to use the smallest blade type connectors. I'm not talking about a OEM style plug but individual crimp type connectors on one wire per connection ( 3 total )

There is one blade type male connector sold at auto stores and maybe even RS that is about 1/8 wide. You would need to cut them down with a pair of sharp wire cutters and then file them smooth and flat.
Once trimmed you should be able to insert them into the factory harness that plugs into the TPS. The wires coming from these connectors will go to your Variable TPS

You can also hack up the stock TPS and solder wires as shown here . https://www.miataturbo.net/forum/t23979/

Can't you just intimidate the connector into fitting? Chuck Norris wouldn't have this problem.

:giggle:

I'm actually just a 14-year old who lives in his grandmother's basement. :cry:

That explains the toys in the avatar !!!! :eek5:


BTW these are the connectrs that I was referring to http://i261.photobucket.com/albums/i...rimpSwitch.jpg

meh, too big and wrong sex. I think DIY may have something, they did before.

like i said, go to autozone, buy a pack of .090" female spade connectors, insert, fill cavity with silicone.

my local vato zone, oreilly, advanced, and napa don't have those. I can't find them in google either, only soldering tips.

wtf?

Has anyone used the Ford Escort GT VTPS from a 98 GT ?

I just came from Advanced Auto and the GT VTPS is cheaper and it is in stock .

the Duralast TPS 0201 is about $30.00 vs Aprox $17.00 for the Ford one

What do you guys think ?

If it fits, run with it.

Even with the OEM '90-'93 Auto TPS, it's not a plug-n-play mechanical matchup for the MT TB. On the manual throttle bodies there's a long shaft which engages a hole in the throttle switch. On the auto bodies, the shaft is short and has a flat plate with tabs protruding from it, and these tabs engage the TPS.

When I converted mine, I cut down the shaft on the throtte body, tapped it, and then used the lathe to fabricate both a small, mushroom shaped piece to sit on the end, with a small stud sticking out to engage the TPS. I then lathed a collar to center the TPS on the throttle body and space it properly. (I used a Honda TPS, but it'd be basically the same gig for a Miata TPS.)

Long story short- no matter which TPS you buy, there's going to be some fab work involved. So if you've got a line on a cheap new Ford part, might as well get it and make it work.

will it fit on the throttle body shaft keyway?

I had stopped at the auto part place on my way from driving my father to the Dr so I was not prepared to size things up...

It seems like I am going to take a leap of faith at some point - Been reading the threads but I've not decided yet on anything.

I'll probably take the stock TPS off and drive to the auto part store and compare the pieces right on the counter.

I'm just trying to comply with the design directives. Cheap, Easy to implement does not require taking the TB off the car and, Robustness oh and did I mention cheap?

Now, if I get a TB from an auto does it just bolt right on ?

That's what I was going to ask. If you have to get the TPS from an auto anyway, why not get the whole TB while you're there? Save the fab work.

I went through duralasts catalog to find the TPS I used, I really wish I could find the part number, because the fab work took me about 15 minutes. IT consisted of marking the postion, removing the guts, screwing two screws and soldering three wires.

really it's not much different than Ben's write-up, i just didnt have to cut the shaft or cover.

Scott, I do not like your new avatar. It scares me.

In the movie The Amittyville Horror there was that evil devil hound that peered out of the attick window..... :eek4:

I have some numbers from another thread Duralast TPS -201 , 4164 and 452 as posible candidates.

These are the threads that i have saved on the subject but can't seem to finish reading because of other responsibilities :vash:

The threads probably cross polinate but maybe it will help someone if they are all in one place .

I remember reading someplace tho, that the VTPS from an auto does not bolt on to a 5 speed TB because the TBs are different between the two cars ( auto and 5 speed ) That seems to be what Joe describes in the previous entry.

When I pick up my evil spawn from school I'll be able to tear off the TPS and see what it takes to convert.

its not his fault, he really wanted those cupcakes.

Hustler, i can send you a few .070 contacts, you'll have to force them on, but that's what I had used.

thanks. I'll check locally first, then holler back at you.

Very funny !! :)

I picked up a VTPS from a 98 Escort at Autozone Duralast TPS 244.

The dooheckey thing looks like this one eBay Motors: 96-99 Ford Taurus TPS Throttle Position Sensor (item 270310031587 end time Feb-26-09 19:26:06 PST)

The stock TPS was brittle - really ! It dies during surgery

The base plate and sort of a plastic bushing remain. I will destroy it further and try to fit the said bushing into the above dooheckey end and JB weld it once the range of travel has been decided on. Thus is the best laid out plan of mice and men.

BTW Do not buy the Duralast TPS 244 it requires rotation oposite to the way the miata Throtle shaft moves.

Anybody know what you set the idle paramemters to to take advantage of the VTPS ?

Thanks

I dont feel like finding the thread for you but I created a thread a while back that joe posted his idle settings in. Find it, use them, they should work.

HA!!! I just searched thru a lot of Joe's threads :giggle:

Ok, I'll look under threads started by you. ;)
