Dec flash results
I had the Dec flash applied on the 30th. I had the Oct flash which was a disaster.
The Dec flash seemed to help acceleration performance, but it is still not as good as it was prior to the Oct. flash. There are obvious changes to the shift points which accounts for the performance increase.
Mileage is the same as post Oct flash.
Still have a vibration in the floorboards at 2000 to 2250 rpm that started after the Oct flash.
Still louder.
Wierd problems with fuel gauge. Filled up at half full. Yes, key was off. Turned on key after filling up. Still showed half full. Stopped and started a couple times in 25 miles before gauge showed full. This happened first tank after Dec flash.
Wait for the next flash.

I have an 03 Excursion 6.0L PSD (March 03 Build)
Just had 15,000 mile service down at 12,300.
Had updated flash (old one was October)... but I am not sure if I got December or January (which somebody said came out)???
Dealer said that their WDS machine is connected at all times via the net for immediate and/or nightly updates from FMC. The service writer and tech did not know which was updated, but whatever one is was done since they update daily from FMC.
Now for the good news....
December (or maybe January)? update has shown the following improvements (or changes) over the October flash.
1) Highway mileage shows 19.0 on overhead computer.
2) Actual mileage vs fuel computed at 20.7 MPG.
(Using #2 winterized with Power Service winter additive for freeze protection and cetane level).
(Outside temp was 32 F to 39F) during driving).
3) Tip-in and Tip-out is firmer with NO lag.
4) Shift points were raised slightly.
5) Idle remained the same, but does slightly run up to 1,000 for cold starts, but drops back down to 600 - 700 RPM's.
6) Idle will raise if temperature drops of idles for a long time. Touch the brake or gas peddal, and RPM's drop back down.
7) A little bit of turbo "wine" is now heard, but not bad - sounds like a 7.3.
All in all, I am very happy with the latest flash (Dec or Jan??). The pro's out-do the cons.
I recommend the latest FLASH!!!!
Good luck to all... Keep Strok'n (I know but I couldn't resist).
Thanks,
