A/T ECU Pinout (Complete) Series 1 Auto Transmission ECU

[Kitty's VR4]

Madhav,

Matching A/T ECU Part # MR470718

I might know where to locate one of these units, I'll send you a PM if its available

 

[Madhav]

Excellent!! Big thanks to you.

 

[Kitty's VR4]

Sorry, Madhav, its not available.....

If you can't source one from a member here, there is always bidjdm.... I'll have a bit of a scout and if I find a A/T ECU I'll PM you links accordingly.

Edit:

Nothing currently on JDM, well not the plastic cased MR470718, there are 3 Metal cased A/T ECU's (Series 1), I'll keep an eye out and shout when any MR470718 come up, they do come up fairly regularly!!!!

 

[Madhav]

Ok, we'll see. thanks for trying

I have one of those ecu but unless you have a AT gearbox with a one way clutch (OWC stamped on the gearbox case) it will not work

 

[Kitty's VR4]

I knew there was something I was forgetting about that ECU, thanks Peter.....reps

its been niggling at me since I put that number up.

Thanks Kat, found that out when we fitted a non owc box to Keith's car

 

[Madhav]

Ohh... so what are my options then? I have a series one legnum auto transmission, sourced the reflashable engine ecu, what can it be paired with?

 

[Guest]

It will still run fine with the preface ecu. That's what we have in Keiths facelift at the moment.

 

[Kitty's VR4]

MH7202 will work fine with Metal cased A/T ECU MD761988

 

[Madhav]

Ok great, I have some options...

 

[merlin]

I now have a auto box controller, it does have a 7202 chip, so theoretically flashable.
Will start hunting for the correct pins to get a connection soon.
Stay tuned!

W00000000000t!

You're the man Merlin!

damm, I need a wiring diagram of the later cars tranny ecu. can anyone help?

 

[SiliconAngel]

Wiring diagram of the ECU?? Don't think you'll have much luck there, Dave - Mitsi would never release something like that knowingly, as the ECU is considered a replacement, non-serviceable component by the manufacturers. Not that it isn't possible someone has reverse-engineered it or an internal document hasn't been leaked somewhere, but unless you speak / read Japanese (or maybe Cyrillic) I don't like your chances.

 

[merlin]

Trev, I mean an tranny-ECU pinout diagram. Guessing it will be different to the earlier units that Kat posted pinout for.

 

[SiliconAngel]

Ah, of course! *facepalm* Say what you mean, man!

Have you asked Kat where she managed to find those S1 diagrams?

 

[merlin]

Kat has dissapeared, not getting any answers or replys.
