PowerFrk Users - How about an Update?

Ok - all of you folks that have installed the PowerFrk unit - how does it work once the temps get over 90 - 100 degrees F. Grif and others have installed them and I searched the archives for updates on the how it worked in high tmeperatures and could not find the information.
My bike still has the throttle hesitation problem (along with high idle and BBS) especially once it gets warm outside.
Any feedback would be greatly appreciated.
Thanks,
Bill

The PowerFRK eliminated the problem of hesitation accelerating from the 2800 to 3200 RPM range, and than sudden hard acceleration. The throttle stop was shimmed out, and the O2 sensor replaced with the PowerFRK installation. The bike is very smooth and a lot easier to ride.
Have only had one 90 degree day to ride in and it rode great, 260 plus miles of two lane twisty roads. Overall about 2500 miles since the installation of the PowerFRK and no regrets.

Previously the bike had the air box replaced etc.

It solved the 2800-3200 rpm flat spot and the related roll-on abruptness. I also did the airbox and ECM upgrade and a new o2 sensor on my '07 GT with 28000 miles.

I live in HELL where it is routinely over 90 degrees up to 105 by 4PM. It's already 95 degrees at 11AM now. No issues with the Power FRK at all. No flat spots (ever!) since the install and the stumbling at 3200 RPM was annoying as hell. The stepper is also shimmed out about 1/2" or so. I also run the high octane Chevron stuff too.

I have a new O2 sensor but never installed it yet since I was awaiting the new airbox to out-gas a bit more as I've heard all the BMW plastic could coat the sensor and I'll await for that to iron out before sticking it on. It's running very well now so I'm not planning to switch it out just yet.

If it ever stumbles again, I'll say something about it.

Does it cure the roll off/engine just died abruptness? Other than the fast idle deal which it is in the shop for now, my 07 is really touchy but smooth on the throttle except for when you roll it off slightly at 70 or above and it feels like you turned off the ignition.

Now that would be great to be rid of. I had an early 900 ducati motor that did the same thing and it made it really hard to be smooth through the technical corners.

Huh?

If it dies, it won't fix that. Just stumbling on acceleration is what I wanted it for and it succeeds in that. It won't cure any of the idle servo/airbox mechanical stuff either, just the crummy fuel mapping BMW uses. If it minimizes that so much the better, but I doubt if it will do that. I haven't seen it reach up and thumb the starter switch yet.

Fwiw, I agree that the GT isn't good in the technical twisties. It sort of wallows like a bloated pig (and it is!). Add some slow turning (i.e. rounded) tires and it can be a handful along with a touchy throttle action (better tighten up the cables a bit so they aren't as sloppy).

I was just browsing the Power FRK website and noticed that it is listed as 2007-2008 GT. Does it work on a 2006 GT. Thanks

Mine's on a 2006. I think they have a typo on their site. Shouldn't be any difference on the Gen. II K1200GT's. Give 'em a call and tell them.

I saw 109 degrees this summer and it worked flawlessly.

I just got in from UPS: front and rear brake pads, two air filters, 4 spark plugs and the new cam tensioner kit. Over 500 bones!!!!!

What was that middle thang?
