I am loving my '05 FEH bought last October. One of the few things that bugs me is NO EV mode above 29-30 MPH. It's so hard to keep it in EV mode w/o people behind me being right on my tail since I have to dawdle along at 27-28 MPH.
Has anyone heard of any way to get the max EV MPH up just a little to like 32 MPH?

 

"Technically" the FEH can travel up to 39.9 MPH in EV mode...
You will see this going downhill or on the flat with a strong tailwind

In my FWD I quite frequently make it to 39.9 or drop into EV at 39.9 when decelerating from a higher speed, but I understand this is more difficult in the 4WD versions.

To get higher EV speed without any "hacks" add more air pressure to your tires.
45 to 50 psi is safe and will increase both your EV MPH and your MPG.

I'm talking about level ground, under some throttle to maintain speed. Yes, I can go up to 40 MPH (downhill usually) if I'm not touching the gas pedal. But if I touch the throttle above 29-30 MPH the ICE starts up.

 

The 2WD can do 35mph with 44psi or more in the tires, it's all about drag in the '05 - '08 FEH. My '09 FEH FWD can do a solid 40mph in EV, even in a moderate headwind. The newer FEH's can do above 40mph in EV, but I understand the generator is turning the engine with the battery to prevent damage to the eCVT above 40mph. In other words, you really drain the battery above 40mph in EV. What I like about my '09 is it has fuel-cut above 40mph decelerating. I glide down to 40mph in fuel-cut, then feel a change to EV and then I can shift to neutral for a long glide. You must stay in "D" to get fuel-cut above 40mph. This is real nice in using high speed Pulse & Glide. This means I can P&G up to 80mph and glide down to 0mph without using any fuel. The newer FEH's and FFH's can go EV above 40mph, but the generator must spend the engine using more SoC. The '05 - '08 FEH's do not have aggressive fuel-cut like the '09 and above. Even my '11 Explorer and '12 Focus has aggressive fuel-cut above 25mph during deceleration.

I'd forget about any computer hack in the '05 - '08 FEH's if I were you. You may cause more damage to the eCVT than it's worth.
