Found this on nico

good stuff. if someone needs to use it I'll create a VQ map for this. needs 64 points so I'll have to interpolate between the points

They had the 2000 Lightning maf transfer numbers too they were a little different than the 01. How do you know which points to pick to make the VQ table?

I start at the top / bottom and then fill the numbers to make 64 points. It takes some time so I'll only do the ones you will actually be using first. Afterwards I have to plug all the numbers into a program to convert it to hex for the VQmap BIN file

Ohh ok. I have the 90mm version in the 1st post.

What do these values mean? Do they represent any actual, real-world data, such as gram/sec of flow, or they are purely abstract, like with jecs AFMs? This may affect conversion table required for nissan

Data collected from Ford guys out here.

Okay then.
The following may look like, and may actually be, complete BS, but here is what i've got after a couple of hours in excel and a small program i've written:

Not having separators sucks big time! The first column is voltage, second - data for R34 MAF, third - Z32 MAF, 4th - the result of my calculations for Ford MAF. Linear interpolation between points, value calculation order - descending, because the highest conversion value for Nissan is always 65535.
I probably should have cleaned up low voltage zone a bit, but it is not clear how Ford MAF behaves at voltages under ~0.5, so i simply linearized, the actual function can be, and quite likely is, rather different though.

This is a first attempt, without complicated methods involved. Feel free to test, use, comment, criticize, etc

Packed up as VQ_MAP file to make tests easier

I'll give it a try when I go back to work on my car. Might be this Friday.

Didn't get a chance this week ran out of time while working on the car. I'll try it next week.

Hey man, any luck with vq numbers?

Haven't been able to test it yet. The car is at my friends shop which is an hour from where I live lol. I don't get to make it out there all the time.

Hey, is there any progress with your testing?
