Could i use and 5 speed ecu with my auto tranny? Just wondering since im having a hard time sourcing a ecu for my 1j swap.
Thanks

 

I don't think so. I'm using an auto ECU with my w58, but I don't think you can do it the other way around.....

 

thats what im thinking. This swap is giving me so much trouble, any suggestions on what i should do?

im just throwing this out there. someone told me i could still wire up my old ecu (2jzge) and give it power and then it will control my Tranny? and still run my 5 speed ecu for the engine.

then someone told me that the tranny already has its own ecu? so

 

I'm not sure about that....I got an engine set that was an auto and it didn't come with a tranny ECU. I guess we could swap ECU's. Do they have all the same connectors and stuff?

 

the auto ecu controls the transmission as well. if you look at the 2 ecu's side by side you will see the auto ecu has a lot more wires.

its not that hard to find auto 1jz ecus. they are all over ebay.

 

What that guy said ^^^^^ you need to use an auto ECU. Do not complicate it by trying to use two main ECUs.

 

thanks for all the input.

but i been looking for a JZA70 Auto Ecu every day and cant find one. Someone give me an link Please! i will love you guys for ever! ha

 

Oh yours is out of a supra? Maybe try calling Jhot. They may have an extra.

 

haha thats why i stated that well i think i did. edit.. i didnt state that but i need one out of a supra!

this is why i am having a hard time. because i need one out of the JZA70 yea (mk3 supra)

 

if you need a soarer 1jz auto ECU i have one.

 

happen to have the harness too? i have a JZA70 harness im open to trade also.

i need the JZA70 ecu more than anything..

but i opened this thread to ask about my other ecu options also (standalone)
just want to hear what everyone is running also.
