Re: EZGO RXV super loud whining
RXV AC motor system has pretty tight rpm control, so much so that if the wheels start spinning on loose dirt, the controller will throttle back to keep the overall acceleration rate as requested by the currently set "time-to-speed" acceleration settings. It knows how long a golf cart should take to reach its set top speed, based on motor rpm "delta" and wont accelerate much faster than that (even down hill). Built-in traction control, lame. But it is pretty safe to run full throttle on jackstands.

Re: EZGO RXV super loud whining
I also have a 2010 rxv electric. Mine is pretty loud too. I have a series cart that was on a golf course and according to everyone I have talked to, the settings on mine would require a purchase of new software to speed it up. about $ 300.00
Mine is pretty loud also but I feel like it is the controller settings that makes it back off when it reaches the controller setpoint. The settings are for safety especially on golf courses. Golf courses don't want carts going 20 MPH on their courses. To me it acts like a governor on a gas motor |

Re: EZGO RXV super loud whining
Maybe with bigger custom wheels (not totally stock). The controller goes 19.5 with the assumption of the diameter of the stock wheels, aftermarket wheels are usually a little bigger diameter than stock, causing a higher top speed (more distance traveled per wheel revolution).

Re: EZGO RXV super loud whining
Is it the cart in your post picture? Black cart/black wheels? Those are not stock wheels. I work at a ezgo dealer, and i can tell you with 100% confidence that there is no "chip", it is all done with software programming (i have done it many times). all 2010 RXVs have the danaher controller, and it is sped up with the handheld programmer and a code. Any "salesman" who tells you about a "chip" is either blowing smoke, or uninformed and has never done the programming themselves. See below stock golf cart tire.
