Your wiring should be:

Red Wire (Pwr)

Green Wire (RPM Signal)

Brown Wire (Ground closest to ECU)

Black Wire (Ground a few cm's from the Brown wire)

Yellow Wire (Air Fuel closest to the ECU in)

White Wire (Air Fuel the other end of the snipped wire)

Grey Wire (Throttle Signal)

Ignore all other wires. You would not need them.

Yep when I accidentally unplugged it it stalled straight away. But not having a screwdriver to plug the wires back in (they got yanked out of the unit itself - long story) and being a few k's from home I had no choice but to try running it without.

It started up fine first kick funnily enough, but then wouldn't rev above 2000 or so. I crawled all the way home at about 40kph, and it was running so rich you could smell the fuel from the cabin sometimes.

It's far from the optimal situation because the extra fuel can wash the oil from your cylinder bores, but 10000km later I've had no issues. It can also foul your plugs. But it's better to have it running too rich than too lean.

With the Yellow/White wire which detects the AFM, it is best to not just join the wires but to get a female/male wire fitting plug as seen in the Apexi manual. This is so if any problems you encounter in the future with the SAFC, all you have to do is unplug the white/yellow wires and plug in the stock ecu by joining the male to the female wire fitting plug. :)

I shit myself when that happened to me. turn off the engine straight away as i thought it will be back to factory settings by just unplugging the harness..

Oh, from my experience, resettings the ECU also helps. Car runs more smoother. :)

      Thoughts on this .. G35-1050 pulsar result

      Nope, still smaller rear, put on the 4inch exhaust and picked up power everywhere, ended up just shy of 800rwhp.   Didn't seem to be hitting any walls either, so perhaps could have pushed for more but all maybes and the fish that got away etc etc.

      This could be sold and shipped to the US for many gold pieces. RMS has no say in that. Ask various Western Sydney inhabitants how it works.

      Ha ha ha, mine loves to spend, all on the dogs (they're our kids, and her spending would likely rival that of some people raising children!) the only benefit is, her spending is tax deductible as she runs a business in the dog industry 😛 The above all means she can spend race car budget quicker than I can. 😛 That and a lot of the things I want are very expensive, and I can be a bit "you want how much for that?!" And at other times overly impulsive. Or I start the w days of research, get to day 1.5 and get really annoyed that no one will advertise actual specifics and it's just marketting BS and I go "well, now I don't want anything to do with that now!" Also I hate paying lots of money for something I can make from $50 in materials. Then I get the shits halfway through making things and wonder why others who just buy parts have more fun... 😛

      Their 240Z with the RB26 would be a real nice thing to have in a garage to come out for an occasional weekend cruise It's such a cool thing in so many ways Sadly, we have a blue 240Z shell that I walk past every day, just sitting outside a shed at work, it has been slowly disintegrating and falling apart into the ground for the last few years, the owner cannot be found, and I am unable to "claim it" I've been told by work and the RMS, the rust in the body is excessive though, and it has had most of the salvageable stuff, like panels, trim and switch gear stripped off it over the last year or two, work keeps threatening to put it in one of our metal scrap bins, I wish they did though, as it makes Mark sad walking past it
