  • ECU tweaking 101

    Hi Everyone,

    I am trying to learn something from the ECU in R15. And I have some question regarding the mod on the ECU.
    Currently I have 2 bikes to experiment with the following setup:
    1. R15 Version 2 Black
    a. Ported head.
    b. Increased the compression

    2. R15 Version 1 Black
    a. Big Valve head
    b. Race concepts cam without the decomp valve.
    c. 61 MM bore kit.
    d. 13 teeth GB sprocket
    e. 42 or even 44 teeth Rear sprocket
    f. Race concepts Air filter.
    I am trying to learn about the ECU Mod for both the above bikes
    I just want to know some details and answers about r15?
    1. What is the AFR of stock r15?
    2. What should AFR for the above setup?
    3. What is the optimum fule1/ignition/correction setting in the race dynamics rtune software?
    4. I know that if the fuel is very lean then it a problem but what if I over fuel it?
    5. Will FI diagnostic tool help me to correct know the errors that I make?

    Please suggest maybe I can try on my bike

    I will keep you posted about the pics of the Race Dynamics ECU tuning software.
