Pretty much got confirmation that Ford engineers are behind these tunes like we suspected. My email from Whipple.
“I dont know exactly what was changed
I was told that they were going to re-enable the shutters for outside air temps below 30 degrees they had shut them off completely
we had a guy in Canada with a misfire problem at wot in extreme cold 20 below so they did a little adjustment for that so depending on how cold it is it might be a little weaker than before in low temps
they said there was a bunch of Ford updates that would help the transmission so sounds like that worked
will have the engineer look at the log and see what he says
they didnt say it would be weaker with the new file.”
Our Ford based calibrations are done by Ford calibration engineers, this has been since 2004.

How do we get the updated tune?

Email just like the time you got the first cal.

Some great info... why would ford chop the power in extreme cold?
Not chopping power, holding consistent power. As temp drops, power goes up, too much power and you exceed fuel system capacity, cylinder pressure limits, etc. The difference between 70deg F to -30F is over 60% more power. We normally only test to 0deg F but some have been driving WOT in negative weather. I do have to say that's a first for us so we came up some changes to the stock shutter system to help control power in the freezing conditions.

I appreciate the info but it’s total crap on Ford’s part.
So they make thousands of changes because their finished product wasn’t really finished....
And do they bother to tell ANYONE.... “hey we have updated the software, come get your FREE ECU UPDATE”????
NO.
Heck.... maybe with an updated flash the transmission would behave appropriately from the factory.
It’s crap... I’m calling Ford Performance and complaining.
All OEM's update/refine calibrations while the vehicle is out in the field. I do our Dodge cals, for each model, each year, there's 5-10 cals and they multiply like gremlins in water. One issue all OEM's have now, the emission standards and technology have to go so fast now that they don't have time to do what they use to do. So they change more after shipment. Then when you go into service, the PCM gets updated.
In the very near future, the over the air flashing will begin to streamline this, not good for any performance enthusiast.

I like Whipple because it’s a complete package, and as far as I can tell it’s backed by Ford performance. My CONCERN is if Whipple will contact the ones that bought their kit with UPDATES for their tune ?
Were not actively contacting customers to let them know we have an update. The base cal, which has been out for more than 12 months now works incredibly well.
