PowerCommander combined or versus John Gemi chip

[pdadenmark]

I have a R1150RT from 2004 with a PowerCommander. And I have a John Gemi chip in the drawer.....

It goes 35 mpg, which is in the lower range? So, - i was wondering, a) keep everything as it is, b) remove the PowerCommander and install the chip or c) keep the PowerCommander and install the chip?

Otherwise the bike runs fine and has just been synchronized.

Thanks in advance!

I have the Power Commander and have it set pretty close to stock, just a little richer in the lower RPM's. You can hook a laptop to mine and adjust the mapping. I get a little over 40 MPG.

What problem are you trying to solve?

What problem are you trying to solve?

The mileage.....

The mileage.....

Then why not the stock chip? Don't they usually return like 40+ mpg?

It's tough to get performance and fuel economy out of the same chip, in my experience.

I have decided to go with the stock setup and start from there. Then new fuel injectors (1200gs), air intakes (1200gs) and experimenting with the CCP.

As I recall, the main reason for the Power Commander and/or “performance” chips back then was an attempt to deal with surging issues common to the 1100/1150 boxer engines. A 2004 should have the improved “dual spark” engine which was BMW’s fix for the surging.

You’re not likely to get much more hp from the 20 year old RT by fiddling with it, certainly not enough to impress any 600cc sport bike rider. I’d return it to stock and enjoy the bike for what it is.

You're probably right..... but you know, sometimes the process is a goal in itself.....
