Hi.
I bought the late zenki JDM ecu.
It is black WC.
I find that JDM late zenki harness has everything like early zenki harness but MAF plug is oval.
It's wierd but i cant figure out whts wrong with this ecu.
I run it on a s14 squareplug maf.
On a days i will fit s14kouki maf.
I'm wondering is it diffrent in sending signals.
The engine starts on this JDM ecu but i cant switch off the engine.
I take the key and it's still working.
It gets boost cut on 0.4bar.
On stock ecu everything goes to normal.

any idea?

Im having the same problem... I brought my JDM harness back and tring to put it in my 240and having obvious problems, so i want to just order a new harness but unsure if its zenki or kouki? i have a PFC so it makes it harder to tell, but the ecu plug is blue and the MAF plug eas oval before i swapped it to a Z32. I have the 2 TPS plugs. Any suggestions!?!?! after reading this thread it sounds like im better off getting a Zenki harness through Wiring Specialties?
