Hey,

I'm building my car slowly, and i was going to use aftermarket ECU but I'm considering engineering and a standard ECU is required unless the engineer can prove it is not fit to purpose.

 

I'm just a bit confused as to which way to go.

 

I have 3 ECU's/2 looms and a motor currently running AFM.

My issue with running the current ECU is it is not a factory ECU.. Well i don't believe it is. It looks very different to what the 4age ones are and it may be from another car because it also is running a 4k style dizzy..

 

 

I have no idea what my loom is from? and i don't know if it will matter?

 

And I have identified one ECU to be from an AE82 with part number 89661-12080 (175700-560 12v)

 

But the other I can not find any information? I found a site saying it was from a 4age corolla but that is all?

don't know if its AFM/MAP bigport or small port part number is 89661-12030 (17500-0313)

 

Can anyone tell me what this ECU is for?

And also how hard it is to make it run MAP if I have a MAP loom and ECU?

Is it just plugging the map sensor in and away I go? or is it more difficult?

 

 

Cheers.

89661-12030 is Japanese market AE82, MAP

 

89661-12080 is also for an AE82 and also MAP

cheers, so they are identical? any benefit to either?

Not the same. The second one is for markets outside Japan, not including USA.

 

Possibly, (I don't know) the Jap ECU may have mapping for higher octane fuel.

cheers, i guess they would be interchangeable anyways so.. when I eventually get it wired ill just see which works better.

 

Should be fun wiring the ecu, at least my aftermarket ecu was labeled..

These ones should also be labelled,.. On the inside of the ECU that is. Take off the cover and you can see the connector layout printed on the PCB.
