MAF Scaling - Calibration

If you find yourself running too rich and what is too rich or too lean? Anything in the double digits so more than 10 or -10 I would tune. If you are a total newb but are in single digits like 8 or -7 that's OK you can leave it alone. Anything 4 or -4 is a good tune already. I shoot for 2 or -2 but that's because I have nothing better to do. ha ha.

You will not get it perfect to 0 or -1 so don't kill yourself trying, the conditions change too much to try for that; weather, humidity, rain, snow, wind, elevation, load (are you towing something?) things outside of your control.

So if you see negative numbers that means you are running too rich, in the example below I would eye ball that and multiple by .97 since I want to take away 3 percent

Again it's better to be a little on the rich side, ie looking green with small negative numbers, -1, -2, up to maybe -4
