EZGO Shuttles no torque
Hi everyone,
I've got 2 friends with EZGO Shuttles, both equipped with the 1268 curtis. One is an ST, the other is an S6 Both of these carts have good battery packs and MINiMAL torque on any sort of incline. I'm talking maybe doing 5mph uphill with 2 adults. Are there commonly known issues with these carts? Perhaps related to the speed sensor? Ive not done a ton of work on the factory shuttles but know that the 1268 is kind of a turd in this application. Thanks for your help |

Re: EZGO Shuttles no torque
That sounds about right, my older '96 shuttle gets the same, about 4-5MPH up hills, 12-14 on flat. I can have 1 person, or 5 and a trailer on the back, and the speeds don't really change at all.

I'm in the middle of a 600 amp Navitas TSX swap on one of them so should wake it up nicely. Just wanted to make sure that it wasn't going to run the exact same afterwards due to some common issue |

Re: EZGO Shuttles no torque
You didn’t say what years but the 2012+ 48 volt shuttle carts were terrible for speed and torque. The motor that was used really needs more voltage to perform. It is around then when they went to 72v

Re: EZGO Shuttles no torque
Yeah sorry one is a 2010 the other a 2014 I believe. Not sure how much has to do with the limitations of the 1268 controller

Re: EZGO Shuttles no torque
I spent a couple of hours with a laptop and a programming cable trying to tweak a 14 with the 1268 with no luck. I talked with Bob and that is when I found out about the issues with the motor. I have used the 1268 in other applications with good success.

Re: EZGO Shuttles no torque
Hmm interesting. The Navitas 600a swap should wake it up though I'd think, right?

Re: EZGO Shuttles no torque
Navitas may help but thinking issue is with the motor. Let us know.
