power commander

Called up San Jose BMW and they said they use the power commander coded for the k1200rs for the LT and the Remus. Has anyone done so ? CUrious to see what the outcome is\was.
Thanks

I have one on an FJR1300 and it is worth every bit of $300. There is no reason I can think of why the RS version would not work on the LT. After all, its just a piggyback on top of the Motronic's fuel maps. As long as the new Bosch 5 wire O2 sensor threads into your exhaust, a custom tuning link map can be made from a dyno run. That way, its specific to your bike's config and the closed-loop ratio can be dialed in to suit on highway cruises. As long as San Jose has got the connector/wiring harness issues resolved, I'd say it's a no brainer to do it.

I would be interested to know how it turns out for you, please keep us posted!

Thanks!

I can't imagine getting the LT on to the dyno. I have dynoed a lot of bikes, and that sounds scary!

i'm pretty sure everything from cams to compression ratios and fuel injectors are different between the LT and the RS. i would think that this might make ignition modules different, too.

The RS/GT PCIII doesn't touch valve or ignition timing at all. Its nothing but an offset correction to the injector duty cycle. I've had the LT on a dyno and its no big deal as long as its strapped properly. Fun to be going 120 MPH standing still. All they do is put the O2 sniffer in the pipe, hold the throttle at 2, 5, 10, 20, 40, 60, 80, 100% open and the dyno loads the wheel to vary the RPM's all the way up at each throttle position. The tuninglink adjusts the fueling to dial right in at 13.1 or whatever Dynojet recommends for the K1200 motor. Then you can adjust the closed loop setting to let the O2 on the bike give you the best mileage at stoic (14.5). I think there is also an accelerator pump option to give it an extra shot of fuel right at throttle opening to further smooth things out especially in really cold weather.

No prob. I had to actually watch them doing it to get it all straight in my head. To do it right, takes about 90-120 minutes on the dyno. Most of the time they have to run through the cycle twice to really dial it in.
