ECU question

[Rathius]

Quick tech question... I have a late model S14 Sr20DET that uses the "NA" coded ecu. I am having issues finding another Ecu of the same type. What I was wondering is if anyone has had any luck using the WC in its place. I know I'd have to get a new harness to match but I wanted to confirm that it would work before I went through the expense and hassle. Anyone done this or know someone who has?

The NA has a different plug than WC. Sorry but you need to find another NA ecu. 1998 kouki S14 blacktop.

or.. you can find a WC with a complete engine harness.

That is what I am doing. I would be getting a brand new harness from wiring specialties. I just wanted to make sure the WC ECU will run my car.

Bump... Still needing to know something about this.

swap the WC harness and ECU into the car

Ok so it will run everything. That's what i was looking for, was if the WC ECU would run my car with the proper harness. Thanks!

Yes it will.. I did the same when I built a Kouki S14 SR..I ditched the NA ECU and S14 Kouki harness for the WC and zenki harness. I did this to be able to run Nistune as well.

Awesome, yeah having a hell of a time getting that NZ Ecu to connect. Thanks for the solid confirmation!
