Maybe my searching skills are lacking, got a used PMAS tune required intake and unless its changed I remember you used to have to change the MAF airflow vs voltage tab along with dialing in the MAF period. So the question is if needed does anyone have a working PMAS MAF table?
What are you putting it in ?
oops that would of helped. 2013 manual 5.0
here you go, this is what I use. just copy over the airflow vs period and the y axis and you should be good to go.stockpmas.hpt
sadly says unable to open file unsupported or newer version detected
you only need to scale ECM 44317, I would start with a 1.3 multiplier, as a quick and dirty base, you will likely need to add more, up to 10% probably but that'll get you close enough to where it should be driveable.
It doesn't have to be perfect, it just needs to be done in two weeks...

try now
stockpmas.hpt
do not touch MAF voltage, Copperheads do not use it. You are going to be working off of MAF period...
PMAS have the MAF transfer tables on there website somewhere
multiplie maf period by 1.95
Is it that much for the pmas?Originally Posted by HPF
I think with my JLT "tune needed" I was at around 1.4 or 1.5ish when I was DONE.

You can calculate a starting point my getting the ratio of new MAF area to old MAF area. New radius squared divided by old radius squared.
yes I'm sure I tuned these several times on new and older coyotes
Thank you for posting this. It got me close but my trims when I clutch in and stopped at a light seem to be off.
