Anyone in here with a JDM Xedos9? (long shot, I know...)

[Lewis7789]

I'm trying to find some info about my motor (JDM KL). It came with a KLK1 ECU which if I'm not mistaken, is from a Xedos9. My question is what MAF (part number) does the Xedos9 run and where could I find one to purchase?

I'm working on a swap and want to run the JDM ECU but need to know which MAF I need. Or I can use my USDM Milly ECU and MAF (KL47) but will get a CEL for the missing EGR.

Thanks in advance for any help!

JDM KL or EDM KL? the jdm is the ZE. EDM is somewhat the same but i can find out from a friedn who live in norway and has a xedos 9.

I'm not 100% positive if it's a JDM or EDM, to be honest. The eBay seller (company) assured me it was a JDM motor and it has a lot of JDM parts and came with the KLK1 ECU so that's what I'm basing most of the motor off of. If your friend from Norway has a KLK1 ECU then apparently I have a EDM KL, which I'm totally fine with. I just need to find out which MAF the KLK1 ECU is paired with from Mazda. And some other info from him would be great too, such as if his motor is OBD2 and if he is running 4 O2 sensors.

I would GREATLY appreciate the help, mate! Thanks!

Check astina gt out, those guys should be able to help...

KL-DE
1993-1997 Mazda MX-6 GT (E and J spec)
1993-1997 Mazda MX-6 LS (A spec)
1993-1997 Ford Probe GT
1992-1995 Ford Telstar TX5 Ghia, TX5 Ghia 4ws
1993-1997 Mazda 626 ES, LX (after 1994)
1995-2002 Mazda Millenia L

actually if it was a xedos9 2.5 engine it should be the same as the milly one. IIRC it is an obd2 and no idea on the amount of O2 sensors. I will ask him to confirm everything.

Well I basically have a Milly motor. It's not a JDM KLZE, that much I know. But it's not a USDM motor either. I've been through this a million times in a million threads. heh-heh.

Thanks for the link, Alex. I'll check out the Aussies too.

Goliat, if you could ask I would greatly appreciate it. I just need some solid info from a solid source. All I am going with about the Xedos9 motor is I looked up the KLK1 ECU and Xedos9 came up. But I'm not sure if they are like the JDM KLZE's where the KL31/36 ECU is mated with the JE-50 VAF and the USDM KLDE's are mated to the USDM VAF. That kind of thang. Like i said, I've got a USDM KL47 Milly ECU and KL47 MAF and I'm sure those will work just fine with the motor btu I would like to run the KLK1 ECU so I won't have to worry about the EGR. I would go coo-coo-banana-crackers having a CEL. But just want to know if I need a EDM or JDM MAF for that ECU or if Mazda used the KL47 MAF for the KLK1 ECU as well. Thanks again!

the Milly engine and the Xedos engine is the same, part from probalby ECU and possibly the MAF/TPS, not sure about those. Anyway I have no precats, there is a distinct difference anyway. To avoid such possible issues after an engine swap, I'd recommend to move over both the IM, the exhaust downpipes and the MAF/TPS from the old engine. If the goal with running another setup is to boost power, I'd definitely ask Renboy. Send him an email or pm. I'm positive he knows about the difference in the MAF/TPS setup, and I'm quite sure he'll say good luck getting that to work LOL.

I remember him saying the JDM Probes run another type anyway, and the ZE engines probably used to sit in those, most of them.

If needed, I can help out tracing a used Xedos 9 MAF setup, just let me know. But don't say I didn't warn about possible issues Using a xedos 9 ECU would probably cause issues too, due to the different cat /O2 sensor sensor setup and what not. There is also a chnce the Xedos ECU is for a 5-speed tranny, another no-go deal.

Hope my answer is to some help.

there is your ans sir.

let me know what else you want me to ask him if that doesnt ans your question or if it wasnt answered in the site scratchnsniff gave you.

Thanks, mate. I won't be running pre-cats (or any cats) on my motor so that's why I was asking about the 02 sensors. I know the KLZE's just run 2 O2 sensors from each bank but the Milly's run 4 total, 2 pre-cat and 2 post-cat. But since I'll be running catless OBX headers I would essentially have to have two O2 sensor bungs welded in and do the non-fouler trick to the 2 post-cat O2 sensors if I would use my KL47 ECU, which I don't want to. It seems like the Xedos9 setup would work better for my application.

I know my motor had an automatic tranny from the factory (but now is mated to a JDM MX-6 5-speed) but I read that the transmission is a seperate module if it's an automatic. Is that so?

Your 98' Milly has four O2 sensors, right?

 

[Goliat6288]

to tell you the truth i dont know much about the tranny since we r stuck with the auto i, nor the members from the other forum, have ever looked into that. ill ask around to see if anyone knows.

actually i have no idea if i have three or four. i know i have 2 precat ones but ive never checked how many i have downstream of the cat

Three o2 sensor system (KL engine with one catalytic converter) - A front sensor is positioned on the LH bank and a middle sensor is positioned on the RH bank upstream of the catalyst for closed loop fuel control. A rear sensor is mounted downstream of the catalyst to monitor its efficiency.

Four o2 sensor system (KJ / KL engine with three catalytic converters) - Front sensors are mounted upstream of the RH and LH warm-up three-way catalyst (WU-TWC) for closed loop fuel control. Rear sensors are mounted downstream of the WU-TWCs to monitor their efficiency

hey lewis. i sent the previous response you put here to another member who is pretty much a guru with these engines. this was his response.

If he sticks to the kl47 ecu (millenia) best bet is to do what he plans but run adjustable O2 simulators on the pre-cat side. He will have to dial them in to prevent the CEL light but after time he can get them just right to prevent that cold start-up CEL. The pre-cat O2 sensors drop out after warm-up either way. He will need to retain the Millenia maf sensor too. I would not recommend sticking with the kl47 though.

The pcm and ecm are integrated. The best bet if he is hooking up a manual transmission is to stick with the odb0 or ObdI kl31 or kl36 mx6 ecm. This is the proper way to do the swap. He will need to stick to his original VAF is he goes this route.

He can run the maf on the mx6 ecu but he will need to do some rewiring.

i hope you understand bc i sure as hell dont. this is way out my league lol.

 

[Lewis7789]

Thanks for all the info, mate. Again, I greatly appreciate the help. And I understand his post, no worries. All these numbers can get confusing. Haha. Looks like I'll revert back to the original plan of running the KL36 and JE-50 VAF with my motor and research that set up some more. Everything he said makes sense and I didn't really want to use the KL47 anyway. I was hoping to use the KLK1 so I can keep it OBD2 and use a MAF for better airflow, but no worries. Thanks again!

glad it helped you sir.
