    Wolverine X4\X2 ECU Reflash

    I saw over the weekend that Weller Racing has apparently defeated the speed and rev limiters the X2/X4. With 27" tires and a machined Sheave they got 63MPH on the dyno. The price is liste at $299 and I am ready to do this unless there is something against it.

    The only video I have seen was with their '18 X4 SE on the dyno... to me just the fact that they defeated the limiters is enough to peak my interests... I am planning to call them today to inquire about getting a whole ECM vs sending mine in.

    I am skeptical that an additional 500 rpm on 27's gets to 63 mph in the real world.

    The speed limiter keeps it from getting to the full 8500 when it's stock..on level it shuts off at 8000 and on a down hill 8350 so the gain is really 1000 rpms even though he is only raising it 500

    I am skeptical that it would actually work myself for those speeds... I would like the small bump on the Rev limiter and removal of the speed limiter.

    That is what I am hoping to gain. I have the JBS Sheave and was able to run at 51mph basically non-stop this weekend. I actually was able to hit 52mph once on a downhill...

    Just wondering if anyone has anything that I should look out for before pulling the trigger on doing this... or if anyone thinks that Alba may step back into the game...

    Gonna be calling Weller when they open. I am interested in spending the money to get another ECM and keeping my stick one. Unfortunately, I believe that my riding season is pretty much done as the trail systems near me are closing for the year...
