I have a 99 road king with a Doebeck file management on it.
Buddy gave me a power commander. If I unhook the negative terminal on the Doebeck can I leave it on the bike, install the power commander and see of I like the power commander better. Saves me from taking the injectors off and the re installing if I don't like the power commander. Anyone see a problem or advice

 

Not sure but why risk it. Even if it does work would you feel 100% confident that it was not interfering in some way.

 

You'll have to put jumpers to re-connect the EFI wires to original configuration.

 

Gentleman. Thank you for the help here is the problem
The firmware needed for the power commander to run in mm efi bikes is the 2.12 firmware. If you load the 2.25 that is for the Delphi system.
So anyone with mm efi you can only update firmware to
2.12. It is not in their website but they will change that to reflect. I thank everyone for their help hopefully my trails will help somone one day.

 

I had Doebeck TFI on mine. I switch for a PC by Fuel Moto. I'm now REALLY happy on how it run. If you do cams, and you have to on a 99-06, PC will work better especially if you order with your setup like i done.
