Jim,
How much fuel was left in your tank? (3/4, 1/2, etc.)? The DTE should operate as a function of your avg mpg, which in itslf with a hybrid could be all over the place. Not making excuses for this case, but if you have lots of fuel left, this could be quite a variance. Take for example you had 12 gal in you tank.

370/12= 30.83 mpg
307/12= 25.58 mpg

So if all of a sudden the FEH "thought" you were getting 25 mpg instead of 30, it could make that jump. (just an example)

I had a chrysler minivan that had this function. A wild guess when the tank was full(20 gal tank)...however got more and more accurate as you got towards empty. Again, not making excuses for Ford...just my .02 cents. :)

Thanks Wayne for the advice but what I was trying to do was recycle my batteries early in the same way I have done with my camera and IPod. There is a learning curve to all devices that store power. I admit I am not an engineer but am acting on my gut.

I have really seen a difference. I realize that if I try to force it too low or too high the firmware in the H-Escape will certainly over rule what I am trying to do. I still feel that the initial firmware is too tight and I am trying to test its limits.

I understand Ford will not update the firmware easily if such a change might adversely affect the extended warranty.

Thanks for you knowledge!

Mike
