ecu #'s
so, now i need to know about the differences between wire harnesses and ecu physical differences of the s4 and s5 t2 and the n/a's.
i've searched (maybe not hard enough) for this info on rotaryressurrection.com, and about 200 pages of archive and new member tech. WHAT DO I DO?!?!:scratch: is there a certain number (ie: n448) or whatever it may be, that i need to attain for my s5 t2 swap? will my s5 n/a wire harness do the job with the added knock sensor wire? will the plug at the ecu side mate with the turbo ecu? are the pin-outs the same? can i use an s4 turbo ecu on the s5 t2? |
You'll find the wiring diagrams and FSM in the 2nd gen FAQ.
There is little in common between the S4 and S5 engine electrical system. |
ok, so is the n370 ecu just the turbo ecu? or is it something special? the n/a i pullled out of my s5 is a n351. will that engine harness plug into the n370 (plus the extra wires)?
|
Yes, N370 is a S5 turbo ECU. S5 NA and turbo engine management harnesses & front harnesses will plug into any of the S5 ECUs, but the pin outs will be slightly different.
Consult the series 5 wiring diagrams and FSM for the differences. It's basically 2 wires that are used differently. Simple stuff. |
there we go! thanks rocket! i've got the fsm saved at home, i'll check those out.
|
ok, so i've searched the fsm, front to back. no pin out diagrams. where do i find the ecu pinouts?
|
S4 NA: Fuel & Emissions 4A-30
S4 Turbo: Fuel & Emissions 4B-30 S5 NA: Fuel & Emissions F1-70 S5 Turbo: Fuel & Emissions F2-77 |
sweet, now where can I find that info? thanks, rocket!!
|
In the S4 & S5 FSMs.
http://www.rotaryheads.com/PDF/2nd_gen/index.html Also links at the top of this forum. |
yeah, so maybe i didn't search hard enough in those, but i couldn't find them. i'll take another look at home, i have them saved.

:wallbash: oh...... i was thinkin those were pin out locations or somethin.. stupid me... thanks, rocket. maybe someday i'll be fast like you. lol
