Tweecer for Ford ECU's

I think this is being looked at wrong.

physicaly it's the same ECU as the ford focus,but tuned for mazda.
the ford ECU we can get into,and is vary available.

how about tuning it to work with a mazda?

we would have better chances,and it would most likely cost less.

I don't know what you are trying to say here. We are trying to use the tweecer to tune the ecu in our cars("a mazda"), to work with... our cars.

Also I'm in the process of building an engine for turbo charging and am still considering which engine management system I want to use. If this will work I'd rather have the ecu tuned correctly instead of having a piggyback either trying to fool the ecu into doing the right thing or modifying the ecu output or going to a full standalone and trying to figure out how to get it to run my gauges. A friend of mine here is a tuner and would like to add this to his repetoir.
That would be sweet if you could give him a visit. You have a PM.

it was intended more for the first page of this thread.



but why go thought the lenghs of doing this tweezer,it's not much different then anything else out for the protege.

seems a lot like a uni-chip.
 
Wicked: Nope, nothing is left plugged in. This modifys the programming of the ECU itself through use of the diagnostic ports, not via a piggyback or similar. *nods* It's subtle, and requires no wiring, and so on, which is why there's particular interest in it, especially in my case.
 
I think it is a cool idea, and as a tuner I'd be interested in working with the software... but the big thing I see being an issue is simply the fact that even after you can decode the ROM there is SO much variables wise to play with I don't think you'll ever be able to solidify a real good tune. And if it is impossible for the end user to be able to tune it themselves because it ends up being so high level then I don't see the point in that either... if those hurdles can be worked around then this could be a very powerful end solution.
 
If you can figure out what the variables actually are.. granted he'll crack it and you'll know that you have a variable XRPump27 but doesn't mean you'll know what to do with it! :)

I just fear that you'll get more work for equal benefit of other things.. you'll spend hours more trying to tune just to get out of an hour of wiring.
 
I certainly don't mind wiring at all. I just rewired a whole Volvo 740 EMS and dash from scratch. =)

That being said, if the variables are wonkey, and hard to ascertain, then yes, it'll take some doing to get the interface to recognize them accordingly. But if it works, then it'd be wonderful, for sure, not to have to crack a darn thing. I'm more curious about what the stock ECU could do, were it tuned properly, than anything else. =)
 
You could also check if the FORD ECU can be used on the Protege. Ive seen part of the pinout on the Probe and its identical.

What's the news? I can't really take off work, and my weekends are usually busy, so I'm hoping someone could go. This weekend I have to install new struts, and I might pull of my intake manifold to replace the gasket that i think is causing a leak. Maybe some day I can make it down.

I think I will contact them. They are in Katy, TX so I might even visit them if they'll let me. I do some programming, and I'm decent at reverse engineering things. I wouldn't mind spending long hours trying to figure out our maps, I just don't have the hardware to do so currently. I'm sure it is hard, but it can't be impossible.

They can read your ECU to find the paremeters. If we send them all types of Protege ECUs, they might be able to hook us up.

Trust me it is not a UNi-chip. It works well but takes a while to learn everything. The Ford ECU is very powerful and complex. Many FI and N/A mustang guys love them.

The guy who owns the company will take your ECU and read it and then let you know if it can be tuned and what the paremetrs are. I haven't did it becuase my MP3 ECU is enough.

Try it out!!

I posted about something like this long ago and got burned by the MPI guys. Oh well...



It should be possible, but we won't know until we try.

BTW, I used one for a while on a Merkur XR4Ti, and it worked well until the combo got so radical that we went to stand alone to solve complexity issues (but hey, there are guys out ther making around 1000rwhp in Mustangs using the Tweecer).

Just think, a FI P5 with a 80-90mm Lightning MAF!!!!(bowdown)

Why not send them a download of the flash from mazdatechinfo.com Someone must have downloaded it ??
I tried to download it, but I didn't see it anywhere on the site. I did manage to leech pretty much everything off that site with my one day membership though.
I think the program they use to actually flash the cars is supposed to automatically download the latest flashes or something. But it wouldn't let me start the program without having a j2351(or some s*** like that) converter hooked up. And those cost about 2k.

Uhm, I can send just the ECU if that's all he needs. I have a spare P5 ECU.

Would you need it back, or charge anything for it? I am emailing him now to see if that would help him at all, not being attached to the car.
 
I would like it back is all, really. I'm not in it for the money; I'd just like a nice tuning option for the Protege. I presently am running the MP3 ECU, and would like to tune that a little further.

I have no real timeframe for getting it back, though. They can borrow it for a few months, if they need.

FWIW, I met a guy a couple of times in VA who has a red P5. He told me that he plugged in an ECU from an FS based Probe.
