    R&D ECU R3 for FZS SHO

    Hi again
    Could I run the R3 with the stock injectors, stock wheel and the Stage 1?

    Yes, the R3 is mapped for stock injectors

    Thanks again. I read earlier posts how you need a high boost wheel and dual prop setup for the R3. I guess that was old news.

    Yes, with stock wheel you should be good. I had issues with running lean after adding a B1 wheel while using an R3 tune. Used a stock depitched prop at the time and did pretty well. When I upgraded to a Fizzle and ET LB wheel I added an external adjustable fuel pressure regulator and all is good.

    I have an O2 sensor installed, only way to know if you are safe or not. The newer tunes available now days are calibrated closer to specific mods,, but I still think an O2 sensor is a good tool to have on a modded ski.
