K1300 engine Mgt

Does anyone know or can find out whether the engine management software used on the K1300 can be loaded and used with our 1200 's? Seems they have supposedly smoothed out the low speed fueling with the 1300's.

Inquiring minds need to know.

I highly doubt it. Different displacement means different fueling requirements. I wouldn't imagine a dealer doing it for you, either.

It might work, but it's certainly not ideal.

I thought everyone was pretty much happy with the later updates?

NOT........I bought an 08, trading my 06 primarily due to all the problems I had with the low speed fueling issues. My 08 was mfg in 3/08. Same problems, maybe a scosch better, but definitely not solved. I know there was at least one software upgrade done after my manufacturing date.Maybe I will have to start the dance all over.

Sorry, not even remotely possible. The K13 engine not only has entirely new fuel mapping, but the combustion chamber and top end has been entirely redesigned by Ricardo. These guys have been tuning gasoline engines for over 100 years and have recently worked on the Bugatti Veryon, as well as working with most of the top motor racing teams out there.

So it's not just a simple software upgrade, but rather an entire engine swap that would be needed to get the results that you're looking for.

I just wish BMW would let them loose on the transmission and final drive. Then we'd have a bike that is as polished and reliable as BMW claims it to be.

It's hard for me to understand the concerns you express with your K1200GT. I also have an '08, made in 03/08. I have no problems with the fuel injection. It requires a good touch on the throttle, but nothing special.

I'd be interested in what you think after you ride a K13. That may change your opinion some, or you may just have gotten one of the good ones.

I'm with wintermute on this. My GT is a 4/08 and throttle has never been an issue, nor anything else for that matter. It will be interesting to compare with a GT13 when ever one arrives near me.

Cheers

I really don't want to start another long string on low speed fueling, but to explain what I experience on my '08, which is what I experienced on my 06.
1. Holding revs perfectly steady while in a low gear below 2K revs the bike will run smoothly for a few seconds, then just die for a second, then stumble until it again reaches the prior steady state.

2. When upshifting especially from 1st or second, the engine will stumble before reaching running speed.

This occurs more when the engine is up to normal operating temp. Living in a low speed restricted area, I must run often at low rpms, thus the discomfort. Highway running with higher throttle settings the motor responds just fine. It is low rpm running that is poor.

Below 2000 RPM is a very low running point for this engine. The idle speed of the engine is 1050 RPM. Could your problems result from running the engine at too low an RPM for the load? Are you in 1st gear when you are trying to run the bike at 2000 RPM?

Yes, first gear. When one must run in the 10 ( I cheat to 15) mph, first gear seems to work best. The bike will idle in first to about 10 in first gear, and does so smoothly. It is when the trrottle is off idle stop when it does not run in a stable fashion. And it is not my hand.
But just running on city streets that symptom coupled with the low speed up-shifting bobble which is the norm of city driving makes it almost unbearable.
