Well, the English are known for making things run well, especially if it involves electrics or electronics....

Woah, this thread blew up today.

Jim, Lemme see if I can jump on this pole.... err... Poll making.

I tried it today. Absorutely no change. Which is good because my 08 has run flawlessly for 128,896 miles.

I'm at half that and felt like a hero, until now...

I'm going to give this a shot on my Silverado. Can't hurt, can it?

B.D.F. · « **Reply #207 on:** September 28, 2014, 09:23:29 AM »

Absolutely not- no harm at all. I've been trying it on everything- my boiler, toilet, wood stove and even the neighbor's dog (she didn't care for the part where I twisted her throttle at all though). No changes or successes yet (though the dog now runs the other way when I call her) but I remain hopeful....

Nope...it's a Chevy.

Might be enough to trigger a recall.

VirginiaJim · « **Reply #210 on:** September 28, 2014, 12:32:23 PM »

Rode and got a baseline on how the bike was responding to the throttle and where the idle was set. Turned the bike off, twisted the throttle twice and then started the bike. No change in anything. Turned off the bike again and did the procedure spelled out here....no change in anything that I can detect. I've never had any issues with the throttle response on this bike except for once when it hiccuped earlier in the year on I85. Changed the filter on the pump and it hasn't happened again. Other than the hiccup, the bike has been stellar throughout 60k miles of riding. The bike has ABS and the throttletamer installed. Cables appear to be adjusted correctly.

Excellent poll BTW.

Tried this on my bike today but as it was running correctly and very well already, I tried to knock it out of correct adjustment. Opened the throttle about 1/4" at the grip edge, then did the 'calibration' sequence, using that 1/4" throttle open point as 'closed' for both cycles. It made no difference in the way the bike runs or idled as far as I can tell.

Ain't life strange, Brian? Seems nothing is ever completely predictable... Unsure why some can seem to confuse the system and then correct, like in the video, and others can't. We may never know why. . . .tomp

Maybe but I really need a predictable, repeatable world around me. I just cannot accept the mystical of any degree or type. So I tend to believe that all things work according to 'the rules', even if we (or I) do not understand all of them (the rules).

And I absolutely agree that we may never know what is going on in this case as it applies to different people and their bikes. ??

And anyway, if this is some kind of magic, it appears that it must be white magic as it does not seem possible to make a bike run worse for having done it. The only two possible outcomes are 1) better or 2) the same.

I tried it today for giggles.....Warm bike. What I have been experiencing before this was, hard to get smooth shifts, that is nice and easy throttle and no head bobbing....bike shifts smooth, just hard to make it seemless. I noticed when trying the Econ mode last Saturday it shifted without me trying so hard to make it a smooth transition, no head jerk if you will. I would normally just try to short shift or get to 4k or so then shift. Now it transitions more smoothly if you will. I also had a nice straight to go to WOT and it just roared and pulled. Don't remember it sounding like that before! LOL Hope this makes sense.....again the bike shifted fine, just hard on me before the recalibration to make it nice. Here is a better explanation.
Imagine riding 2 up and when shifting she would hit your helmet. Now will not happen. Make sense?

? Hard to explain stuff sometimes in writing.

BruceR · « **Reply #215 on:** September 29, 2014, 05:31:57 PM »

It seems to have worked on the truck- I noticed it most when turning a corner in town. Used to lurch when it went from idle to on the gas again, abrupt throttle opening. She's smooth now. Haven't been out on the bike yet, but my bike didn't have any real problems anyway.

Oh, the mysteries of life and motor vehicles, filled with magic and electronics, that even the designers don't understand.

FWIW, Read about any Rx drug in a PDR, and you will learn that most all action descriptions start with, "This drug works in an unknown manner..." Guess drugs and motor vehicles have a lot in common.

I was talking to a guy the other day about doing a certified Iron Butt ride...
He's been going on about every year I've known him, but hasn't done one yet.

I said, "well, if it was easy, then everybody would be doing it"...lol.

He says, "Oh, I've done it before, just not a certified ride..."

I said, "without certification, it doesn't exist...lol".

Haha...that was the end of the conversation unfortunately...lol.

Kinda like, "Without pictures, it never happened." Especially effective when crashing on a dirt bike in front of other riders. Normally they are all laughing and pointing so much, they forget to take out the cameras, so, no pics, it never happened. Ask me how I know. . .tp

Son of Pappy · « **Reply #219 on:** September 29, 2014, 08:28:08 PM »

Looks like several Positive results, many no changes, and zero negatives. A win win in most books.

Is there a similar poll on the other forums? If so, similar results? Fully getting the no pics/documentation it never happened (2 1286 mile day trips in a seven day period, documented, never filed, THEY happened, and plenty of off road off bike occurrences that never made primetime digits), but based on what I am seeing SOMETHING is happening and it APPEARS nothing negative. Surely there must be some type of empirical data out there.

Brian, any luck with MJTP at Mama Kaw?
