Who Has Wired Up An Ecu In An Auto Stagea S1?

Just in the process of planning out my ECU install. Ive been supplied a wiring diagram for the install, and there are some discrepancies between the one supplied and the ECU pinout which I found on this forum. Ive attached the one found on this forum.

For example, on the forum's wiring diagram:

Pin 101 - Fuel Injector 1

Pin 103 - Fuel Injector 3

Pin 105 - Fuel Injector 5

Pin 110 - Fuel Injector 2

Pin 112 - Fuel Injector 4

Pin 114 - Fuel Injector 6

On the ECU wiring diagram:

Pin 101 - Fuel Injector 1

Pin 103 - Fuel Injector 3

Pin 105 - Fuel Injector 2

Pin 110 - Fuel Injector 5

Pin 112 - Fuel Injector 6

Pin 114 - Fuel Injector 4

The ECU will be semi-sequential. The firing cylinder pairings makes sense: 1-6 2-5 3-4

Shouldn't injector pairing be the same? Half sprayed at an open intake, half sprayed at a closed?

Ill consult with the ECU tech support, but I wanted to check with the SAU community whether the attached pinout here is indeed correct, or whether there are different series 1 ecu's, or perhaps the ECU diagram is based on an auto skyline etc...

Addendum 1: Judging by this document, amongst other sources, wiring injector pairs 1-6 2-5 3-4 is a functioning way. However a better option is 1-5 3-6 2-4 (however I don't like the asymmetry of it).

That makes more sense on the ECU's wiring diagram, however the pin numbers are still different.

If you cut the injector wires at the ECU, you should be able to determine the injectors by probing each ECU pin and coil plug with a multimeter?

      Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).

      What brakes on R34 GTT(Europe)

      I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.

      R32 GT-R: 4WD Light Turns On After Bumps – Code 19 (ETS Motor) But No Issues Found

      Agreed, and in particular the earth strap that should go from the subframe to the chassis but it often broken or left off. There is a section in the R32 workshop manual you can follow for troubleshooting if you don't see anything suspicious, and depending where you are (there is no location on your user profile) you should be able to get your hands on a second hand replacement unit still if needed

      What brakes on R34 GTT(Europe)

      Yeah they mention as a R34 for 2.5 Turbo...but then again thos "small" were also for R34 by that different site. But i look into it and that 310mm EBC is for R34 GTT. And by those you linked the specs are the same 🙂    EDIT: I found these on one site here: DBA 4000 series T3 DBA42304S They are 310mm...and it says are for R34GTT...are there good? EDIT2: ok they have pads too.  What "color" should i get for street use? I dont want/need some noisy ones...(and if they are not that dusty that is good too)
