here is a perfect Nismo afm voltage curve. (it was optimised with 700cc injectors) as with any curve it will need small tweaks to suit your injectors, pressure and pump etc....

Commanded AFR's were spot on with a result of 397awkw

copy and paste the whole table into the afm table.

Sorry to bump this old thread, but I was wondering if someone could answer my question regarding these Nismo AFMs and setting them in the PFC.

I have the voltage table setup just as Status posted (thanks by the way for posting that up), and I am using FC Edit. I have it idling well with a OK AFR at those settings.

The issue I am running into is that I can't get the ECU to run in a lower load cell. It idles in the 4th load cell and on decel the lowest it will go is the 2nd one. It currently will not go low enough to cut fuel on decel.

If I use the VG30 option and use the % correction that was posted above, the car idles really lean and lopes.

Which of these should I start with and correct? I understand one is measured voltages and the other is just a % correction of the VG30 values? I'm a bit confused as to which one I should pick (or which one is better).

      Kinkstah, no, coilovers aren't illegal, especially as a bolt straight in. The illegal part will be if they're altering suspension geometry beyond factory limits, or the ride height is not legal.   Sounds like the blue slipper just didn't want to deal with any later possibility of mods appearing on the car.

      The problem has always been that coilovers are able to be adjusted, almost at any time, to be too low. Most people who ever get/got defected for/with coilovers were actually afoul of the minimum ride height rule. So the interpretation by cops/inspectors was always that it is pointless to allow numpty to raise his coilovers and get the car inspected/cleared, then just drop them back down again as soon as they get around the corner from the inspection station.  This led to the interpretation that they were illegal unless rendered such that they can't be adjusted (ie, collars welded to the body, that sort of thing). That may or may not have ever actually been the official line, but I'm pretty sure it's not considered to be a solution these days. Coilovers themselves fall under clause 3.2 b of that manual, because they are an "installation of a variable ride height system" and they don't fit the exclusions in that clause (which point to air springs and other pneumatic adjusters). So, as per previous statements, they require engineering cert to be legal on the road. Once you have such cert, provided you do not adjust them outside the height range covered by the cert, you are OK. Without, you have an unroadworthy vehicle.

      Here E10 is the cheapest fuel. And general advice is to not use it unless you hate your car. From what I remember it clogs up stuff in the fuel system or injectors?  With US/Canada being E10 across the board, does that mean that all fuel there is terrible?

      Sorry, are coilovers ACTUALLY ILLEGAL in NSW? They aren't in Vic, as long as they retain 70% of stock travel and the car is above 100mm off the ground. Does NSW actually have a law making coilovers actually illegal? RWC/Blue Slip/Engineering people not knowing the actual f**king laws boils my blood. Demand them to point to the documentation that states a coilover is illegal. (it may exist in NSW ) Edit: I checked. They aren't. https://www.nsw.gov.au/sites/default/files/2021-02/RMS-infosheet-light-vehicle-modifications-manual-suspension-and-ride-height.pdf
