    S3 - What Adj Ring Size and any Prop Tweaks with Stock ECU?

    Just installed a Rive S3 Charger. What is the best place to start (mods in my sig) for a stock ECU? I tweaked the prop by -2mm for the Green wheel, will it matter much?

    If your RPMs are correct in your sig. then I would leave your prop alone and put in the 83mm ring..

    Start With 83

    Start With 83 And Work Your Way Down If Needed.......

    Shoot For 8100 On The Nose.....

    When I ran similar mods to yours with the Riva SC3, 15/20R -2mm and the 81mm ring I would have 10.3 PSI boost at 8100-8120 with 77.5 mph.
