RXV and Liberty Lithium max speed tuning 30MPH

[kgsc]

The yat software and the txt file..

Kris, if you're talking to me, I was referring to an S4 Curtis Programming File. If you have one I would like to see it.

Sorry buddy don’t have one that new. I meant with the yat software you probably need the txt file to load so you can see the parameter settings on the screen.

Follow same procedure for Liberty 1206AC-5250

Any idea if this would work on a 1206AC-5201 ?

With 20.5" tire that RXV with a 1206AC-5201 controller can be programmed to go 30mph right now with the right programmer.

I haven't been successful getting the 1314 on PC into developer mode and suspect that would be necessary. So, if this procedure works it seems to be an easier path.

If you unlocked profile 5 freedom mode I think it will work for you

I've got a 22 Liberty Lithium. We like everything about the cart except the take off torque is ridiculously low. I think the battery is limiting power when taking off from 0. With 2 adults in the cart I cannot stop on hills in our neighborhood or on the golf cart path of our neighborhood golf course or it won't start back. If I am going 3mph or faster there is no problem accelerating more when going up same hills. It just won't start off on them. Any way I could use this to help? Tech has already been out and turned on 25mph and said he turned on strongest hill climbing setting. But I have to think there is some setting still not letting it get enough voltage or something when starting off.

I am fairly experienced in working on carts so any advice would be great. The dealer said they can't do anything more for me. I am thinking about taking out the samsung lithium and putting in a 3rd party lithium battery so that I can upgrade controller. It really sucks to have visitors riding around the neighborhood with me and ask them to get out of the cart if I stop on a hill.

The main issue is the liberty comes with a 235 amp Curtis, not a 350 amp. So it makes sense starting on a hill is difficult versus driving into a hill and carrying some momentum. Reach out to ezgo customer care and tell them the situation, I as well want to see them offer a 350 amp controller like the express 6 comes with..
