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?
Suggestion, and not an easy one to follow. Someone with a bike that is running as the OPs before "Calibration", hook the KDS up, run a diagnostic. Do the procedure, re check numbers.
Another, easier idea. KDS, in hand, get a base reading as it stands on a warm bike. Do the procedure with a throttle lock stopping the throttle say %20 from true closed. Without moving the throttle lock, check to get another reading. Remove the throttle lock, third set of readings, and finally, do the procedure again, and get a final reading.
%20 may be too large of a variance, so maybe %10?
I suggest that this could be about some sort of mechanical hangup in the throttle system - grip, cables, throttle shaft and spring, etc.; due to dirt or grime. The full turn procedure merely "clears" the mechanical hangup.
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.

Using a scale of 1000, 0 being full closed, 1000 being full open (Made up numbers for simplicity, I aint no stinking engineer) if the ECU is reading %1.5 off? Once "Reset" the air/fuel ratios are matched and results in a smooth transition from off idle...
Interesting. It seems as if those of us with great running 08's, like you Jim, and myself, don't see the astounding changes purported, and no change in idle.
BUT, did you actually do the procedure during a ride, with the bike fully up to temp? And then further ride it as a comparo?
More food for thought. The PCIII and PCV both require "Calibration", it gets the readings from the TPS and it makes a difference, those same readings are being read/sent to the ECU. Maybe there is a procedure during assembly that has been skipped on some bikes? Maybe the bikes with PCs installed unwittingly reset (For Brian )the ECU to the correct reading.
The TPS is a critical part of the ECU and FI. It doesn't take much to make things bad.

I do not have any type of Kawi source/contact, if I did I would be asking them, surely out of curiosity someone will make the call?

Just curious. I keep following this thread, waiting for somebody to offer up some type of logical explanation, other than what they "feel" in how the engine runs.

Gee, didn't you like my logical explanation? You know, the one about wiping the entire surface of the potentiometer with the internal (Easy Boys!) wiper?

Hey!!! I shower every second thursday, whether I need it or not
