JDM KL Millenia swap into my Protege5 thread

[Lewis7789]

Sorry guys, I really gotta stop calling it a JDM "Millenia" motor since they never had a Millenia over there. I have a Xedos8 or Xedos9 motor.

So I'm going to ditch the '94 PGT harness and use a USDM '96 Milly harness from a cat over on 247 who was going to do this same swap on his MP3. He said it's OBD2 so I might actually be able to pass inspection. heh-heh. And it would be much less of a headache.

I've got a shop looking into seeing if they have any JDM MAF's for the Xedos motor. I'm trying to stick to the JDM KLK1 ECU that came with the motor and just trying to verify if the Xedos 8/9 still used the KL47 MAF in Japan or if it was a little different. But much like the MP3 ECU in my P5, I want to get the most out of the ECU as well.

[tour96se]

have you verified the cams and heads yet? it'll help you decide what ecu/vaf to use

[Lewis7789]

Yeah. The cams are NOT flat top and the heads are KL-101 and KL-1A1. Oval ports. I read that only the '95 Milly motors have square ports on the heads.

[PrinceValorum]

The cams are NOT flat top..

I think you've researched enough for one day..

[Lewis7789]

Oh man, haha! Soup brain for sure.

I checked the cams, they're not KL31 cams, IIRC they were KL-01. Which they are supposed to be.

I'm also working on a swap right now for my MSP, but I have 2 issues time and money. Plus I need to unload a bunch of stuff to make enough room for the work. Good luck to ya using OME ecu's.

[Lewis7789]

Well, fortunately for me, I have plenty of time and thus a decent budget (no wife/kids and an understanding girlfriend).

My build is still going strong. I will update this thread when I get home from work.

I assume you mean "OEM ECU's". Was that sarcasm or not? I have a all the wiring, ECU and MAF sensor from a 1996 OBD2 USDM Millenia for my swap so hopefully it will go smoothly. I need to dive into the wiring this week.

[Lewis7789]

Well I've hit yet another snag with my swap.

Apparently the KLK1 (JDM ECU that came with the motor) and the KL47 (USDM 1996 OBD2 ECU) are both internally wired for an automatic tranny and won't work with my 5-speed? I though the automatic tranny's had a seperate control module. I was really hoping to use all my KL47 parts and wiring and keep the car OBD2, especially since I spent $560 on the ECU, MAF, complete wiring harness, 4 O2 sensors and disty.

If that's true then how come the KL36 (JDM ATX ECU) works just fine?

If someone could help me out with th wiring of this beast I would greatly appreciate it. haha. It's turning into a real bloody headache...

As far as ECU's and VAF/MAFs I currently have;
-KL47 ECU and KL47 MAF (USDM 1996 OBD2 Millenia)
-KLK1 ECU (JDM ECU still hunting down which MAF it needs)
-KL36 ECU and JE-50 VAF.

As far as wiring harnesses I currently have;
-1994 PGT engine and MTX harness
-1996 USDM Millenia engine and ATX harness
-???? JDM Xedos9 (Or whatever the hell this motor came out of) partial engine harness.

Go to the junk yard and get a wiring harness from a 1993 car, then you won't have the fan issue if you use a KL36/JE50. Or get one from an OBD2 car and use the KL47 stuff. If I were you, I would use the KL47 stuff with an OBD2 harness. The motor you have wouldn't really benefit from KLZE electronics.

[Lewis7789]

Well I already have an OBD2 wiring harness from a 1996 USDM Milly.

I guess my main question is is it true the KL47 and KLK1 ECU's won't work becuase they are for ATX? I didn't think the ECU/transmission mattered?

[94mx6lsze]

I'm not 100% sure on that one. The good thing is that ECUs and VAFs are cheap and abundant in the junk yard, returnable, and very easy to plug in/unplug. Get an ECU and VAF from any manual transmission OBD 2 Probe, MX6, or 626 and you won't have to worry about it. You can just see what one works. BTW, are you planning to sell the KL36 if you don't use it?

[Lewis7789]

Well I don't want to spend any more money than I have to, ya know?

I've got 3 ECU/VAF, MAF setups in my garage right now and I would like to run the one that is best for my application is what I'm getting at.

I would like to run the KLK1 ECU and KL47 MAF and be OBD2, so yes I would sell the KL36 ECU and JE-50 VAF to someone else in search of them.

[94mx6lsze]

How much do you want for just the ECU? I already have like 3 JE50's lol.

[Lewis7789]

It's currently not for sale until I am 100% positive I will not be using it. But I'll let you know.

[dragonballspeed]

Lewis, I have to ask what your goals are here, do you just want a KL swapped P5 or do you want boost also. If you're looking to go further than the swap drop all the factory wiring anf ecu's and get a Haltech. You will be much happier in the end with the results you can obtain. If that's not an option, talk to Pope540 on Mazdas247 and he should be able to help. He went the route you are trying with the wiring
