Ok so I was totally oblivious to my ecu and wire harness until hooking everything back up. and this is what I noticed.....




So im wondering can i run the ecu over the top of the tranny and through the original hole and mount it where mine is? or can i use just a plain s5 wire harness on this engine setup and call it a day? but one possible problem this . . . ..



what is this ECU? and will a different numbered ECU be able to run this engine? Also the engine is fully emission removed and the inside of the s4 is stripped running nothing inside, fully gutted. Ill be switching to a rtek 2.1 in a few months.

K let me be more specific what I'm asking. 1. What model Ecu is this? 2. Does rtek support it? 3. Is there a way to make this wireharness and ECU fit in a LHD chassis? Will a normal S5 wireharness and ECU be able to run this engine?

 

n374 might now work.

 

What?

 

Wildchild you have like three threads that all are asking roughly the same thing. I just replied to your last one, which sort of neglected to mention that this was a S4 -> S5 swap.

Regardless, refer to the other thread. That is a N374 ecu, Rtek will only touch the 2.x mod as of now. as per their website.

all other questions are answered in https://www.rx7club.com/2nd-generation-specific-1986-1992-17/knightsport-ecu-engine-different-wireharness-977471/

I'll reply to your picture thread too.
