    VXs/r 2011-2012 ECU Different P/N?

    I was told that the ECU P/N is different between the 2 years.....I seem to be limited to 7680 RPMs on my ski while 1200 stx-r was able to turn close to 7900 RPM......This is on STOCK ECU....Anybody else with a 2011 VXs/r seeing the same thing?....... Some one have a 2011 Service Manual.....?

    But I'm curious though, why do you feel like you are limited at 7680?

    Is that from a 2011 or 2012 service manual?

    The image is from a 2011 manual. It's interesting you say that about 7680, because that's all I can get on my ski as well. Do you have any mods done that should put you over 7680? Minus the FF exhaust my two skis are identical, except one does 400 more RPM than the other. I'm starting to wondering if 7680 is indicative of something else.

    I have a DIY Air Intake, Riva FF Exhaust, Ribbon Delete, a few fresh air mods......If I go out in flat smooth water and make a run , the tach shows a top RPM of 7680 every time....unless I get out and jump some wakes off big boats and hold the throttle open a little longer than I should it will read higher......

    It could just be props at that point. We're about to try a Skat 12/18 on my two skis to see what it does to the RPM. If the Skat prop increases RPM on my daughter's ski, but still runs at 7680 then we know its some sort of problem. Hopefully this is all just a question of getting the right prop pitch. Seems like 1200stx-r has the right prop pitch for the stock rev limiter. I think his is a 12/17 Skat if I remember correctly.

    My PET tachometer shows 7750-7950 on my 2011 consistently. Not sure aabout ECU part number?

    NOTE: MEANT TO SAY 7750-7850, I HAVE NEVER SEEN 7900 ON A VXR WITH A STOCK PROP.

    I noticed the typo after reading Jarrett's post on page 2.
