11' Mustang w/ 3.7, MAF tuning?

[Jay@HAP]

I'm trying to tun a 11' Mustang with a 3.7 V6. In the scanner, MAF period is not an available PID to log. AFAIK, you need to make changes to the MAF period table like the V8's.

Is this PCM different for some reason? I know I can't be the 1st person to tune a 3.7.

I submitted a ticket to support last week to see if I could get it added but I haven't heard back from them and they haven't responded to any of my emails.

Any info would be appreciated.

Is MAF Hz available? If so its any easy conversion from Hz to period.

yes it is. I had actually just sat down at the computer to find out if there was a way to convert hz to period.

Can you share how to do that?

did I do the math correctly? I've had problems in the past figuring out where the brackets go for the formula to work correctly.

i went back and changed the value to 1000000, i didn't have enough zero's...i think

What is MAF period?

It is the time the electricity spends moving in one direction through the heated wire before switching direction and moving the other way.

hertz is how many times it switches its direction in one second. The more it switches back and forth the greater its heating ability.

In a analog MAF the electricity is always flowing in one direction and as the Voltage increases its heating ability increases.

Hopefully you can see why a digital MAF is a lot more capable than an analog MAf that is limited by maximum voltage.

Thank you.
