Latest flash
I like the way my truck operates now. I have the flash from late '08 or '09 where the "Cleaning Exhaust Filter" message stays on until the job is done. I do not make any oil and never have in 73K miles according to my oil analyses.
What are the pros and cons of this new flash? Will it really fix something that may cause damage that Ford will refuse to warranty or is that just a ploy to get my truck back in the shop? TIA

It appears to tighten down the sensors to protect the motor better. You loose the constant message.
I don't have it yet either. Mine too runs just fine like it is. Suppose we will have to get it sometime though.

I'm not 100% on this but I either read it in the letter or on here. The new programming is primarily to reduce the amount of time it takes the truck to go limp mode and shut down when there is extream oil growth, water in the fuel and a couple other issues which require very expensive repairs. Presumably going limp would save the motor from total failures. It appears Ford is tired of paying the high dollars to fix the 6.4Ls. Anyway, the punch line was that if you got the letter and did NOT get the truck reprogramed then they would not make the repairs under warranty if you had one of the problems that the reprogram would have prevented. Like I said I'm not 100 percent and any lawyer could punch all kinds of holes in it but thats what I read, somewhere.

Got mine flashed yesterday while in for 50k service. Truck went into regen today and still had the "Cleaning Exhaust Filter" message. Not sure if they really did the update.

Maybe they restored the constant message with this new flash? How 'bout all the rest of y'all that have the latest flash and have had a regen? Anybody been there and done that without the message staying on 'til the job is complete?

Had mine flashed a week ago. only driven 50 to 75 miles, no real changes seems the same. No regen yet, but I hope when it does the message stays on until complete. I agree with you guy's my truck runs great. Hope this flash doesn't change that. Time will tell.

No changes to the regen messaging on my '10. The cleaning exhaust message pops up for about 2 seconds and goes away assuming I notice it. I've had 5 partial regens since I got reflashed 600miles ago.
I haven't had a regen complete to know how far between regens it is with the new flash yet. However, it doesn't appear to behave any differently than before. I was really hoping they learned something from Banks to implement a cleaner tune. I guess not!!
I'll hand-calc my mpgs again when I refuel next week. Based on where my fuel gauge is and miles I have on this tank, I don't think there's any mpg improvement. LOM has been sitting at 14.6mpg for quite some time (I never reset it), and that interestingly corresponds to the hand-calc'd average of my last 4 fillups over 1000miles. Compared to roughly the same time last year with similar driving patterns, it's not much different.

This morning I got another regen. It started about a minute before stopping at a long stop light. It was about 50F outside...When that happens, things cool down and I typically belch white smoke for a couple of minutes as I accelerate. This time, I smoked a line of cars behind me up a steep half-mile hill at 20mph. I'm sure everyone behind me was cussing. Their windows were open after I got to the top.
SO... definitely no changes to the way regen works...
