    Whats the RPM limiter on the VXs/r?

    I am curious to what the RPM limiter is on the the VXs/r....I have an after market Tach and every time after riding it shows a top RPM of 7680.....was wondering if that is when the soft limiter kicks in......????

    After all my mods I was running 7,800 and I would hit the limiter when going through light chop or when turning around the course. I just installed V-tech's re-flash (8,350 rev limit and more aggressive timing curves) and gained 150 RPMS right away (2 mph) and I'm no longer hitting the rev limiter on light chop or going around the course, Julio...

    I think what you mean is that there is a soft limiter, you can just run up to the max rpm allowed by the ecu if the ecu doesnt sense any rapid increase in acceleration. I'm not 100% sure of this but I have to imagine that the VXR/s ecu has the same soft limiter the sho engine has.

    Yeah thats what I am trying to figure out, like I said I can only get a max RPM reading of 7680 no matter what.....just was thinking thats when the soft limiter was kicking in.....I have the tach wire run to the number one cylinder......may be it starts cutting spark at 7680.....????
