Yes, exactly. I had the one in August done. My Eco still doesn't persist, but the car longer down shifts two gears when accelerating on cruise control.

I haven't noticed any other differences, but really didn't have any issues besides CC.

SC, were having issues while on Cruise Control? When I'm set at 60ish, I feel like if the GC was giving and taking on gas/speed...like if I had my foot on the peddle and giving / releasing...very light tho...just enough to drive me crazy on long trips....

Based on the TSB, it would seem that the Aug 2014 TCM flash update had various shift fixes, but the Feb 2015 release simply adds Eco Mode persistence in addition to the fixes in the August 2014 release.
The flash for ECO didnt work on the 5.7, i had it performed a few days ago and others have reported the same. My guess is that it wont work on the diesel either. Has the ECO flash worked for anyone that we are aware of?

So, what I'm hearing from you and Silvermax is that:
1) This TCM flash does not implement the only thing the TSB claims the flash implements (i.e. Eco Mode persistence), and
2) No one has any idea what this TCM flash actually changes.

Lol that is as near as i can tell. The only thing on the list to fix it didnt lol. I did try pulling yhe battrry cable afterwards as i have often found that fixes many of the electrical flash gremlins. No luck for this one it just plain doesnt work.

There is a new flash out for the diesel PCM that looks like it adds to a whole laundry list of things.

Maybe I'll give the flash a shot. I just had a really crappy experience in traffic today. Floored it from a standstill in Sport mode and had an "excellent" double-lurch that literally jerked me and my passengers around.

Should have done a brake-spool-turbo launch instead.

So after driving for a little more than a week with the flash, I can say that the car will stay in taller gears longer now (which I love) and use the turbo more, rather than down shifting at the slightest hint of accelerator pedal.

Re: TSB - Shift improvements for 2014 3.0L Diesel (Feb 28/2015)

Had 21-012-15 performed the other day. Shifting does seem to be improved but maybe it's wishful thinking. Need more time to eval... Mileage is still good, 28-30 highway. ECO setting still resets during power cycles. FYI, had a 200c loaner and the 9 speed shifting is terrible...
