Foolin' the ECU...

Install your powercommander if you need to. Basically you jack into the throttle position sensor, the injector harness, and ground to battery. Don't yet load the supercharger map, you'll need one suited to your bike for a few tests later on. Lots of maps available for free at the Powercommander website.

P.S. you have to have power to the powercommander module to upload a map. As in having the bike running or applying a 9v battery. New ones come with a 9V adapter plug, but you can make one up easily, here's the pinout....

Key must be on, kill switch on. Bike running if you don't have the 9v jacked in. now connect the mini usb to your laptop running the software program. The mini usb must be fully seated to work. Push harder than you think...it'll click.

Upload your map. Done.



Now you have to fool your ECU into thinking it's still controlling the exhaust powervalve if you bike still has one. Simply remove the cables connecting the servo motor(under the passenger seat area) to the valve. This leaves the valve open (good for boost) but still lets the computer spin it's little servo motor and think it's controlling the valve, so, no error lights.
