2015 C14 Chat/Changes

There was mention elsewhere of a possible catalytic change and also ECU programming related to at least the first gear change, but also possibly emissions.  So far I haven't seen anything definitive about it, so it still seems more like a rumor.  My concern is, while *nobody* cares about some possible internal catalytic change (talk about meaningless), a change to the ECU programming could greatly affect compatibility with the Guhl flash and maybe also a [non-autotuning] PCV.

...a change to the ECU programming could greatly affect compatibility with the Guhl flash and maybe also a [non-autotuning] PCV.

I don't think it would greatly effect anything. Outside of the STP map changes in the Guhl ECU reflash, the changes in fueling were very minimal, so to make a Guhl ECU flash work on a 2015 with a slightly changed FI ECU wouldn't be any more work than simply copying and pasting.

As far as a PCV is concerned, it shouldn't effect anything at all. The PCV doesn't care what is in the ECU...it only modifies the signal between the ECU and the throttlebody assembly, nothing more.

I'd bet the FI ECU changes have more to do with the new linked braking action than first gear improvements...but that's just my own guesstimate;).

OK, that is good news, then, as long as Kawasaki hasn't played anything tricky on us.  I had thoughts of "as long as we are in here messing around, might as well change the DRM/passwords/etc, which could make things a pain for Guhl.  Seems like a low probability, though.

I think your guesstimate is pretty dern good.

Too bad they didn't fix the high beam indicator (make it dimmer). WHen using the high beams, that things is like a blue laser, burning into my eye.

I detailed my fix for that excessively bright high beam indicator way back in 2009 on the original forum before they erased it and all the tech stuff that was posted. (Supposedly to prevent a big legal battle)
I'll look around for my original instructions on the fix.  There is a very specific value resistor you need to add to the back side of your dash panel. Pretty easy fix.

We would be most grateful..

Sorry Jim,
  The text is gone and I have no notes on the size of the resistor.  The indicator is an LED and I 'believe' the resistor is something very low, like 56 Ohms installed inline with the
Red supply wire at position #1 of the indicator/Display connector as described on page 16-104 of the hard copy 2010 Service manual.
  I'll remove the heat-shrink tubing from my resistor if I'm ever back in that area. I had to try several different values to get the indicator dimmed but not off.  As it is, my indicator is visible in daylight but not blinding at night. Mine is on a lot since I have the headlamp modulators installed. 
I will add a picture here:

Thanks, Mick.

I have split off the stuff not about 2015 reviews into this thread.  The other/original thread is here: http://www.zggtr.org/index.php?topic=18571.0

As supplied by fartymarty, the only change in gears (all else is the same, including final drive):

2008-2014 1st gear = 3.333 (50/15)
2015 1st gear = 3.538 (46/13)
