FROM EXPERIENCE.. best ECU for KLZE swap
FROM EXPERIENCE.. best ECU for KLZE swap
Before anyone starts telling me to hit the search button I'm wanting opinion from those who have done the switch. I dont know whether to buy a KL31/36 and just straight swap it, to use my K8 ECU for the time being or whether to buy a KLZE chipped ECU from ebay (I am VERY dubious about these though).
I am going to be starting with the K8 Dissy and JE50 VAF from my K8 too. Which ECU would we go for??

well if you would have searched i guess you would have discovered that kl36 ecu is for curved neck klze and kl31 ecu is for straight neck, but you tols us not to ask you to search. Also you would have found out you can get 1rstprobinator to chip your ecu for less than what the ecu costs anywhere but well I cant tell you to search for the info ![Razz :P](./images/smilies/icon_razz.gif)

Holly misinformation...not at all. There are no proper ECU's for the curved-neck ZE. The KL31 and KL36 ECU's are for the straight neck KLZE and the VRIS points are programmed for that. It was theorized that the KL31 was for manual gearbox and KL36 for automatic transmission, but they've been found in their respective counter parts as well (and if you check in an auto Mx-3, there's a seperate ECU for the auto tranny), so in essence, no one knows the difference between a KL31 and KL36, however, they are both for straight neck KLZE's. Either way, they work best with the stock JE50 VAFhgallegos915 wrote:well if you would have searched i guess you would have discovered that kl36 ecu is for curved neck klze and kl31 ecu is for straight neck
Another setup that apparently works well is the stock KLDE ECU and VAF combo.
If you want a proper ECU, it would be to get one, could even be your K8 ECu (except early 92's), get a Probinator reprogrammed for your proper KLZE.
eBay rechipped "performance" upgrades are just boxes with resistors that trick the ECU into dumping more fuel, not effecient since more fuel does not mean more power (a proper air/fuel mix that is more lean usually leads more power) and jsut wastes gas.

all this talk about ecu's....
so can i take an atx ecu from a 93 626 and do my swap to the 92 gs mtx model as long as i use the ecu and vaf from the 626?? will it matter coming from an auto to the manual trans? (since the auto mx-3 has a different ecu than the mtx one i guess.
also the motor will be a klde correct?

no, the pinouts on the 626 are different, unless u have time to rewire your harness connector u can do thatwvurubberducky wrote:all this talk about ecu's....

I was under the impression that a KL-31 ECU works best with KL-31 cams and the KL-36 ECU works best with KL-01 cams... I could be wrong... but I've had successful results with mine!!
I'm running KL-01 cams with a KL-36 ECU (modified with no rev limiter or fuel cutoff)... I tried it with the stock k8 but it runs like crap... and way too rich... just my personal experience![Shrug :shrug:](./images/smilies/shrug.gif)

I dont think so. I dont believe the ECU has anything to do with the transmission, the Mx-3's have a seperate ECU for the ATX I believe. I'm farily sure you can plug in any K-series OBDI ECU between the Mx-3, Probe, Mx-6 and 626.bdr2k5 wrote:no, the pinouts on the 626 are different, unless u have time to rewire your harness connector u can do thatwvurubberducky wrote:all this talk about ecu's....

Lotsa theories, some say 36 is for auto hile 31 are for manuals, but they've been found in their respective counterparts as well. Besides, that theory doesn't work because both those ECU's dont have the right VRIS points set for a curved-neck ZE, and the KL-01 cams only come in the curved-neck.Mooneggs wrote:I was under the impression that a KL-31 ECU works best with KL-31 cams and the KL-36 ECU works best with KL-01 cams...

I ran my K8 ECU for a week before my 36 arrived, and i totally agree, ran as rich as a mofo.
No idea, and technicallt it's a MAF, but it would use the MAF out of whatever vehicle the ECU came out ofho bag wrote:Is there an OBDII ecu for any kl motor that can be used in a OBDII mx3? and what vaf would it use?

so are you saying that I have the wrong ECU? what are people who have kl-01 cams supposed to do LOL???!Nd4SpdSe wrote:Besides, that theory doesn't work because both those ECU's dont have the right VRIS points set for a curved-neck ZE, and the KL-01 cams only come in the curved-neck.

my vris kicks in at around 4400 then again around 5500 and man does it KICK - so is my theory correct based on those facts?!!!

It's not about the cams, but it's a problem with anyone, either 01 or 31 cams, who is using the curved-neck intake manifold. The VRIS points are configured accorind to the IM, not the cams, I'm farily sure, but it could be true that the cams are taken into consideration because of the fact that they would have the 31 cams with the straight neck. People have been runing 31/36 ECU's on ZE'd with 01 cam'd Mx-3's for years. Not to say you wont run right or fast, oh and she'll still kick, it's just that it's not configured 100% according to what the ECU is setup for. That's the reason why some people are obsessed with getting 31 cam'd straight neck in Mx-3's...Although you can get a Probinator ECU configured for your, or any, setup, what will actually usually yeild more gains above that is a megasquirt systemMooneggs wrote:so are you saying that I have the wrong ECU? what are people who have kl-01 cams supposed to do LOL???!![]()
