no letter for me...i am not going to do it anyway. Must be some select ones that get.

No letter here either but I dont want it either too much of a hassel with the mini maxx and no dpf. Would just give dealer a chance to make note of changes to the truck.

This might be a dumb question but what's the min max? Does this have something to do with the IH maxx engine that is similar to the 6.4

no letter either.. I'm thinking of getting it before I put the spartan on..

Thanks. Gotcha

I just attached koboss's picture to his post earlier. Here it is if anyone missed it:

Letter just arrived today.
 

Mine showed up in the mail 3-19.

I never got the letter, I just went in and had it done. Now to install my banks.

no letter and i am not convinced that for me it is the right thing to do.

No letter here (yet). It sounds like there are some good features in the new firmware, but there are also some bad features.

In particular, I take my truck off road into fields regularly and not having a continuous regen message is a serious fire hazard driving / parking over dry grass. On a couple occasions the truck has been in regen as I approached the field so I took a small detour to allow it to complete and temperatures to return to normal before I drove in the field.

Certainly there has been enough negative commentary on these forums about the later firmware not giving continuous regen notification. I find it distrubing the Ford has apparently not paid attention to those complaints.

Just had my update done this morning. Had not received a letter yet, but I figured I most likely would receive the letter (which service verified by my VIN#), so hopefully there is some realized mileage or other benefit besides putting the truck into limp mode prematurely.

A couple of things I've noticed since they reflashed mine a week or so ago...I think.

It seems to shift smoother, especially in TOW/HAUL. That is noticeably different.

The other is that I seem to be getting a better mileage, hand calculated, that what the LOM is indicating. (That I am not that sure of as I haven't been on any extended runs of late). For instance I topped off the tank yesterday with about 10 gallons of liquid gold. The LOM indicated 15.8 MPG and I hand calc'd 16.5. Interesting.

That was an interesting attachment that got posted on here with the info on this PCM recalibration. It was just done for me at a service interval I had. I had no say in it at all. I never saw that letter that was attached. Its good to know that it is a PCM retraining type of thing. that way I can keep my wife out of it for awhile so she doesn't do her 24 hours at Lemans style of vehicle ops before I get a chance to train it! :-jammin

I just got my letter on the weekend. Now just have to find a day I can find to take it in.

I get the feeling they're doing this primarily to minimize their warranty costs.

I doubt they'd ever say 'improved mpgs' in the flash, otherwise, everyone and his distant relatives will be lining up to get it. :-)

I think we might have started getting a non-winter blend of fuel. My mpgs seem to be better in the past few weeks here in San Jose... so let's see how this goes...

my letter came today.
