massimo msu 500

I have a massimo 500 when in reverse and i accelerate it stalls like there is a rev limiter any solutions would help

Ok

My MSU 500 does not rev up  in reverse. either . so it must be a limit in reverse only

I can't back up a hill unless I get a rolling start Can you. Have you looked into bypassing the limiter?

[Joe Breaux]

same here.. it seems to be some kind of safety feature , not allowing fast reverse .. dont know how you would bypass it . let me know if you find a way

This should take care of it. Check out his advice & knowledge page which is where I got this from.
