Mostly riding in SoCal, it's not that big of an issue, but yes the GSW heated grips do not run as hot as my 2007 GS heated grips.

New GSW Heated Grip explanation WTF?

I found this on the UK GS site, haven’t tried it but an interesting explanation typical for BMW
So it is not the grips, it is the over engineered complicated electrickery telling the grips what to do. Another BMW example of perceived progress.
Got the bike back and yup this does seem to be the problem, over complicated control gizmos.
But the explanation and word around does seem to hold up.
First bit of advice is to actively switch the grips off before you switch off the ignition, don't leave them on. If the bike is started with the grips on, they will hold around 40% poewr and will not improve when the bike is running.
So start the bike, get it moving, then switch them on.
When you slow down for junctions / lights etc. the revs drop to below 2k, the grips drop to 40%
But once the revs exceed 3k, the grips go back to 100% power.
Is this a faff, Yup!
Is it an acceptable fix, Hell No!
Are my hands warmer now I have been re-taught to use a simple on off switch, YES,

I am the OP of this thread and my grips on my '13 GSW still suck.

I just bought a '14 R1200RTW and the heated grips get nice and hot to the point where I have to turn them down even with grip puppies.

Come on BMW both of these bikes have the same Linbus computer system. Only difference is the GS has high and low and the RT has five or six settings.

I want my GS grips hot like the RT.

I will do the temperature experiment I mentioned above using both bikes.

Mine are fantastic. I usually have to switch to low after a few minutes. Riding in low 40s here. 2014 GSW

Grip Heat at Idle

Took mine in for the run-in check and was talking to the service manager.
He said he received info from BMW to pass on to riders. Apparently when the bike is at idle the power to the heated grips drops to 50% of whatever setting to prevent power drain. Then go back to set power when back to speed.

Today I took the temperature of the grips on my '13 GSW and my '14 RTW. Both have grip puppies and both were ridden a little over ten miles each before the test. Temperatures were taken with bikes in neutral and at 4k rpm with the grips on high. The RTs grips are 7 degrees hotter than the GSW which confirms what I already knew. The heated grips on my GSW suck.

The good news is both right and left grips are the same temperature on each bike.

On the RT the grips don't run cooler when the bike is at idle. I will test this out on the GSW and report back.

I am going to print out these photos and have my dealer do a PUMA report on my GSW. From past experience I expect BMW will ignore my problem.

I've never had heated grips before, so these are good for me

I have found a big difference in the grip heat output between my 2011 RT and the GSAW. The grips on the new bike get nowhere as hot as on the RT. On the GSAW, the high setting is just at or even slightly below the heat that was on my RT when they were set to low. Will ask the dealer about it when I do the run in next week.

Hotter Grips

I wonder if there was an update to the software when I took mine in for service. On the way home I was riding in 30 degree temps and could feel the warmth through my heavy winter gloves even when on low grip heat.
Seemed to be warmer than before servicing. Of course, that might just be wishful (or delusional) thinking on my part.

We can only hope. I'm assuming it has to be a software issue. Once the RT parts fiche is release I'll check to see if the grips have the same part numbers.
