making a 2007 PDA faster?

[Texas Skeeter]

My neighbor just picked up a nice conditioned Yamaha 2007 48v PDA he was told. It has the tow button under the seat, the forward/reverse switch on the dash and a little connector just hanging above the batteries just dangling there. the seller stated this cart has the capability of supposedly using a PDA to turn up/tweak the speed faster. Is this possible and if so how or using what device/program? it currently does approx 15mph cause we raced each other HaHa....Oh and he lost!!

Update..... i found a local dealer for my neighbor here in DFW. He has purchased the "PTV" code for 150$ having given them his cart and controller S#'s. The code will be avail in 5 days. Then he needs to take em the cart to program it/test it and pay another 75$/1-hr labor. We shall see how it goes. They stated he should get it up to 19mph, so we shall see.....

It sounds like it has some potential for more speed with the PTV code. However the labor cost for installation seems a bit steep, especially since it's a quick process. The code should bump up the speed to around 19 mph, but make sure that the installation is done correctly to avoid any issues. To get it any faster might be a stretch without significantly over revving the motor or compromising other components. Hi speed gears could potentially help, but they might not be suitable for hilly terrain due to the strain they put on the motor. The higher torque demand can lead to greater strain on the motor's rotor, bearings, and windings, potentially accelerating wear and reducing the motor's lifespan. Additionally, the increased workload may result in higher operating temperatures, further exacerbating the stress on the motor and increasing the risk of overheating.

Since Yamaha hasn't produced a series cart since the G-16E and newer models are "sepex," there may be some challenges in implementing certain upgrades. For instance, the YDRE throttle sensor operates on a 0-5 volt system rather than an ohms-based throttle, which could affect compatibility with certain controllers. However, controllers like the Alltrax SPM series that support 0-5 volt systems might offer some potential for upgrades. Additionally, swapping in a series motor and controller could significantly boost the cart's speed, potentially achieving speeds over 25 mph without gears.
