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

[BlueRB240]

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

[BlueRB240]

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

[Legionnaire]

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

[BlueRB240]

Data collected from Ford guys out here.

[Legionnaire]

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

[Legionnaire]

Packed up as VQ_MAP file to make tests easier

[BlueRB240]

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

[BlueRB240]

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

[Legionnaire]

Hey man, any luck with vq numbers?

[BlueRB240]

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.

[Legionnaire]

Hey, is there any progress with your testing?
