For what it's worth...don't go over 30MPH
On my way to work today I stopped by my dealer to share my upgrades with them. I mentioned that I had programmed my cart to go 28 MPH. The owner happened to be in the service bay and warned me that Icon told them NOT to program carts to run over 30 MPH because that can fry the programmer altogether. I thought this was interesting based on another thread on this forum that said an Icon shut down while running at high speeds. While that owners situation tuned out okay I think all of us should take note.

The other poster who's cart shut down was due to the BMS (battery management system) and not the controller because he has a lithium pack and they have their own special controls...not much to do with the controller. I don't think the guy knows what he's talking about. I spoke (on the phone) directly to the guy in charge of writing the software and implementing it for the controller and he said he had them going 10k RPMs in the factory. That's likely not under load, but it would lead me to believe the controller isn't going to just fry for going over 30mph. I asked my EE BIL and he said the following: Quote:

Re: For what it's worth...don't go over 30MPH
Atrain, I set my forward acceleration to 7000 but can't seem to break 30 MPH. Is there another setting?

Re: For what it's worth...don't go over 30MPH
I think the guys hitting 32 MPH may live in hillier areas than me. On my usual route to my in laws, I only hit 30 MPH -31MPH on one stretch. Its about 3 blocks without a stop sign. Approx 1600 feet and has a small down hill grade about 3/4 of the way. It takes some space to get to 29-30MPH. Cart (at least stock tuned) goes 0-25MPH much quicker than 25-30MPH.

Re: For what it's worth...don't go over 30MPH
Agree, seems to take forever to get up to 30. I have mine set at 7000 so technically, shouldn’t it get up to 35? 7000/200? I may be missing another setting. As we start to figure all this out I’m sure there’s a setting for acceleration as well.

I have a whole list of settings/parameters to change from my EE BIL and from others on the forum. I'll have my cable back in a week or two where I can do a more legit writeup after doing some of my own testing. I don't want to start throwing random changes out without doing my due diligence first and making clear what the changes are. So know I do plan to put some info out there. |

Right, smart approach. I thought I read about some one here that have had their carts going 35+ I guess that's downhill, not straightaways.

Ive not found the ratio number to be accurate. So it was set to 5000RPM and I was hitting 25 MPH on the dash speedo (less per GPS but not the point). I changed to 7000 RPM max and Ive never seen 35MPH EVER. I got 32MPH tops on a long straightaway with just myself recently. Freshly paved road with no potholes and nice and smooth. I see 30 MPH with enough space. Im hoping one of these days I have time to let wife max it out and have the laptop hooked up and set to monitor things so I can see what the readouts are. |

Re: For what it's worth...don't go over 30MPH
Would like to make a suggestion...understand that in these areas
my knowledge is 0 but.... Could it just maybe be that the 4 gauge battery cable need upgrading to 2 gauge to accomplish your 31+ mph speed objective ? With my other... hobby audio...upgrading stock power cords to better quality heavier gauge allows a better power ebb and flow as the music demands instantaneously...the result is impressive.. Just thinking that the 4 gauge wires maybe hindering the additional current our carts need for higher speeds (rpms) along with more torque. Somehow I think there is a similarity and that being current limiting. Alas I'm no expert where all programming things cart wise are related... Just an idea.. Best wishes to all Happy cartin' |

Yes definitely would lend to better and more efficient energy output/draw. Ive been meaning to look at what gauge cables are on the batteries. I changed them out on my TXT and saw improvements for sure.
