... and here's another thought. I read somewhere that possibly Corksport can reprogram an LX ecu into a GTX ecu. Wouldn't that be nice .... maybe I wouldn't even have to mess with the harness (?).

Asked them once for it they told me they had a modified computer but for the 1.6l ecu (mx-3) and not the 1.8l ecu that we have in the lx dohc. If you find information that would sugest they now have it email me please i would really like to know

There is a company out of New Zealand, Gizzmo Electronics that is working on a ECU replacement for the 1.8l BPT. They currently have the 1.6 available. They sent me an email stating that they were going to be releasing the GTX ECU replacement. Im not too sure of the details, but generally the ECU should remove the 1bar boost cut, and provide a fuel map beyond. I don't have their URL handy at the moment, but if no one post's it, I will post the site later.
As far as the extending the harness, I'll try to help, but from what I remember, it was just a lot of soldering, and heat shrink. There were 2 connectors that had to be reconfigured to match the Protege. Now a european GTX harness would be the way to go, though you would still need to reset the 2 connnects.
Personally, I am very happy with the GTX ECU, it starts every time, the idle is smooth and no muckin abouts with the setup. I like the reliablity factor, and will forgo big boost for the peace of mind that it will work well in any climate. It is designed as a daily driver after all. I figure when I want more power, I will probably look at picking up the Gizzmo ECU. As I've heard lots of good things about the B6T version.

Do they take a n/a 1.8l dohc ecu and change the programmation so that you can run the gtx with it or his it a gtx modified. If it's a n/a modified to run the gtx i would really be interested

Well, I probably won't hear back from CorkSport until Monday, and I hope it's not Ben or I'm going to have to call them instead of emailing. He's the one that originally told me there was no turbo made for my car ! I suppose he was technically correct, but still ....

Now I'm wondering if the LX dohc harness can be adpated for use with the GTX ecu. Braden has a GTX ecu that I would like to buy because the price is good, but his harness is missing some connectors. Another guy here, limpgtx, posted that CorkSport wired his GTX ecu using his stock harness, although he has a 323. I don't know if there's any differences between the dohc and 323 harness, but obviously CorkSport knows how to do it. I know I've read somewhere that the LX harness just needs a couple extra wires - this would seem pretty simple. Any guru's out there know about this?

atila

for start the gtx tps has 4 wires and the lx manual has 3 wires other then that i don't know for shure

turbo1g

it would be easier to re do lx harnes.like somone said tps has extra wire and u need run couple extra wires for knock sensor and knock sensor module. plug for knock sensor module can be found on junk yard on mx-6 turbo so its easier to do lx harnes than to modify gtx

I agree with turbo1g, that if you knew what wires you needed to run, the LX harness would be the way to go. It really was very time consuming extending the J-spec harness. I would just double check the manual to see that all the wires are going to where the GTX ECU expects. At the time I didn't have the proper factory wiring diagrams so I opted for the j-spec harnes to be sure.
Turbo1g, are you sure that the MX-6 Turbo knock control module will work with the GTX ECU? Corksport told me otherwise when I was looking for one.

Here's the URL for the site I mentioned:

So if the GTX ecu has a 4-wire tps, then I wouldn't need one of the wires if I plan on using my RX-7 VAF, right? I just need to figure out which one isn't used. If I could get the wiring diagrams for both the GTX ecu and the LX ecu, than that should help. Rick, I've emailed that guy twice for the CD, but no response. Did your CD have the diagrams for both ecu's? Got a CD burner?! Also, does anyone know for sure if the connectors going into the LX ecu will plug into the GTX ecu? I'm assuming they do, but we all know what happens when we assume!

Rick, didn't you get a knock sensor with your motor? Are there two different things I need - knock sensor and knock module? I'm guessing the MX-6 turbo you guys are referring to is the 1st gen MX-6?

<edit> Here's the link for the documentation on CD. "We have service and wiring diagrams for 1988 North American 323 (incl GT/GTX) and 1990-1994 Protege/323/GTX/GTR available on CD in indexed .pdf format."

i dont think u can use spare wire from vaf.the tps wire in gtx is shilded wire,its like antena wire so it dont pick up interfirence. u can get thatwire in radio shock and run it along lx harnes.

beachnut

Ok I get it (I think) - I do need the 4th tps wire, and I only have 3 right now. So, along with the two for the knock sensor, that's makes 3 new wires?

If somebody hasnt mentioned it..... the Pro LX Auto has a 4 wire.

If you don't want much more than what the stock GTX puts out I would think a GTX ECU would be the best bet (even with the wiring mess). Be aware though that you can get decent stand alones like the Microtech LT8 for under $800 right in the US.

Aussie hookups always help if you want a Haltech

Marlon

is it cheaper in australia cause my friend lives there

superdave

Generally yes. Even with people here offering 'good' deals on Haltechs I can still get one a decent amount cheaper from aus even after customs, taxes, shipping, etc. Talk to your buddy.
