Where would i go about sending a Pro-M to get recalibrated for some 24# injectors?

They took over where Pro-M left off. If it's a Pro-M, they charge $100 for re-cal. OEM MAF's they charge $200. They told me usual turn around time was about 3-5 business days.


I'll put holes in him!!

WOW. Don't do that.
With all the new tech that has released for the Contour/Cougar in the last 2 years there is NO reason for that. Not to mention that is a hit or miss thing ANYWAY, and if ProM is still in business it will cost you a good chunk.
The easy way is to just retune your pcm.
Besides, that recalibration crap doesn't work on our cars for fuel adjustments more than say 20% and even if it gets it close you will have unknow problems that crop up as a result of the load miscalculations that are caused in the PCM from the recalibrated MAF.

Get an XCAL2 with your stock code, 24# injectors, and a MAF transfer function matched to your ProM75mm. Then you will be in business.

Cliffs Notes of Warmonger's post: Don't do it!

Aaron, you'd probably benefit from going back to the stock MAF, and getting a tune.

Ok. Thay is what i wanted to know. I have the PRP, but i wasn't sure if the MAF HAD TO BE programmed for your injectors. So i can just use Advantage to setup a Pro-M 75mm MAF to run on some 24# Accel's i have??? I kinda have another car to drive that gets about 40mpg so i wanted to start seriously messing with this software i spent 600 bucks on lol.

I am getting pretty familiar with the software now...but i really do not know how to come up with a MAF Transfer Function. Isn't there a "manual" that SCT makes that explains how to tune using their software?

And just to get this straight...if i buy a Pro-M 75mm MAF i will not have to get it reprogrammed for injectors...i can tune it in using the software i already have correct?

You will need to get the MAF transfer function from Pro-M, or whoever is now producing the MAF. From EVERYONE I've ever talked to with tuning, tuning an aftermarket MAF is a lot harder than with OEM parts. If you just want to go bigger, grab a Lightning 80mm MAF, or just stick with your stock Cougar MAF. Unless you're going F/I, w/ the exception of nitrous(which I know you are running ), then there's no real need to go bigger.

I'm not runnning nitrous

So...IF i did do this where would i get the transfer function for the Lightning MAF? I think all the Pro-M MAFs come with a sheet that tells you what they are, but what about a the Lightning?

Yes its $100. Turn around time 2 days...for me atleast. Just installed a Pro-M 80mm.


Failure is simply the opportunity to begin again, this time more intelligently.

i have a 75mm prom and it worked good untill i switched from a modified s.e. air box to a modified svt air box. the pro m maf doesn have a better internal design though. it looks less estrictive. is there any way to convert to a m.a.p. sensor.

I have a 75mm Pro-M MAF that's already calibrated for 24# injectors. Shoot me a PM if you want it.
