I ride a road star warrior and my friend rides an 03 R6. Both are sweet bikes. I found info on adjusting the stock ecu for the warrior and for an FJR1300 but nothing on the R6. On my warrior it will allow you to adjust the fuel level one cylinder at a time. I thought this was usefull so I wanted to know if it could be done on the R6. This is a yamaha secret.
DO NOT atempt to do this. This can damage the expensive ECU. Here are the links for the warrior and FJR.
