Procharger Stage II MAF Calibration-Issues

[sonic]

Not going to end up frustrated.

I will win regardless of how much time and money I have to throw at this thing.

I like your style:cheers:

I always wondered about Procharger's maf placement and how it can possibly measure airflow correctly when the air is coming at it from two different sides.

Hi All-
I am new to the forums. I recently purchased a new Mustang GT.

After about 300 miles, I installed a Stage II Procharger kit with F-1A Procharger, ID-1000's, and a JMS Fuel Max, ARH Longtube headers, and a catback.

I am in the process of refining the MAF calibration via HP tuners. Anyone have any examples of a stage II Procharger MAF table that has worked well?

I am just curious if I am heading in the right direction. I e-mailed Procharger tech support to get internal dimensions for the intercooler, but never got a response. (I also am curious how the MAF meters 100% of the air in its installed location)

Right now, I am have some issues with the car falling on its face at WOT and trying to rule out some items. Runs and idles great, just has issues with high loads.

Thanks,

Have you tried HP's forum? I would think someone there would be willing to help you. It's been awhile for me, but I know one of the leads at HP was on there helping a bit. I've since forgotten his name.

Isnt the HP software and tuning credits = to the price of a Ngauge and lund tune?

I have more in this setup than the Ngauge and lund tune.

I am more interested in being able to modify the tune as needed than price.

Do you have any tuning experience? If not I wouldn't try and try and tackle this on your own. The s550 platform has been a challenge to say the least for the best in the business. I've self tuned Fox body Mustangs for years, with PMS, SCT, Quarter Horse, Megasquirts and ProM EFI and I would attemp to now where to begin with this very complex tuning strategy.

It doesn't.

I am not sure why it's placed there.

You can put a maf in a tree 5 miles away from a car and calibrate the velocity as the car drives by.

Its proper calibration that matters and the new strategy is nothing to a seasoned tuner. All the hearsay is horse poo.

Good luck with that!

I don't know why Procharger wouldn't give you a MAF curve for a Stage 2 setup. But if not, you can turn long term fuel trims off. Drive around and verify actual a/f ratio compared to demanded. And look at fuel trims in the log too. Use these variables to get short term trims close to 1 and actual a/f equal to demanded a/f. Some imports to excel and math and you will find out multipliers via rpm to apply to your current maf scaling. All should be done at part throttle and limited rpm until you get it close. Btw, make sure and apply smoothing to the curve, you don't want a jagged maf curve when you are done.

That's the theory behind it. Have never looked at the ecu for the Coyote though, but have done this on another car.

All the tuners Lock their tunes. No one will give you the file. Others tunes have had their tunes stolen and copied for that reason. The 2015 PCM are way more complicated than the 11-14 and you don't have the avg blower. I totally get where your coming from but I think your going to end up frustrated with a vehicle that doesn't run correctly

Only Ford tuners really, and only a few of them.

Its nearly unheard of in the GM world to find a locked tune.
(If you do that as a tuner in the GM world, people figure you are trying to hide a poor job of tuning)

And in the diesel world, you can find free tunes all over the internet, since everyone shares everything.


Sadly due to our "liability" stuff, we can't send MAF curves out on tuner kits. To many finger pointers back in the day ruined all of that.

Its the most stable signal, AND gives the customer tons of range. (so you don't peg the meter, with high HP builds)

We started doing it, and I know at least Hellion has started to as well.

Its very very easy to calibrate the MAF in that location,
And its very repeatable. (when making 100-200 intercoolers at a time)

Well sell thousands of intercoolers a year with MAFs in them. (Ford and GM)
To hear a complaint is very very rare. (1 or 2 a year)

I agree. I came from the GM world. I have had every LSX vehicle under the sun. That is why I found it weird that all the tunes are locked on this side of the fence. Maybe I need to build an LS550 :eyebulge:

I still have a LSX block in the shop.

Oh well.

Since I see the ls1 in his screen name I am going to assume he is coming from the LSX world were self tuning is occurring and people are sharing knowledge and tunes.
