Ok, so the data logging went a little weird too. I was watching the screen and it showed pedal position 97/98 when I was full throttle. Should that have been 100? Also, the datalog came out strange too. I can't figure out how to link my log file though.

So, here are links to the data logs. The are both the same, but I converted one to an Excel file. Is it weird that it doesn't record battery current, and that the ThrottlePos doesn't read the same as the laptop screen did?

I was just reading this post here: Alltrax - only getting 17-19mph

This guy is set to Field Map #6 because that is what for a stock motor and that is what PQ told him to set his to. When they first installed my controller it was going on a stock motor. But they then put in the D&D motor. I wonder if I should be on a different field map. Also, I wonder why mine only shows 97/98 instead of 100 for pedal position.

Ok, I might be getting to a conclusion on this. The 98% thing was a problem for sure. I got ahold of Ron Manns at Alltrax, and he sent me a couple new hex files to load. The first one compensates for 98% throttle problem, and now my cart actually hits the 100%. The second file he sent was a new Field Map file. I am now getting between 24 and 26 mph on flat ground. He said my motor is some custom D&D motor which is why I can't find any specs on it. It is definitely monstrous torque because my speed is still increasing on the way up the hills by my house, and I can do 22 up a hill that I normally can only do about 16mph up. Kind of impressive really. He also told me to dial back the throttle up rate to take out the jerkiness at launch, and now it is a much more manageable throttle. Now I need to solve a few other problems like my lights dimming from this 500amp controller. I also need to solve a charger problem, but I will start new threads for both of those.

That performance sounds more like what you should be getting, top speed is also a function of the voltage at the motor, which in your case is no longer optimal. It would appear that new batteries are in your near future anyway, so that will improve.

A few thoughts:

1) Manageable Throttle:
As I mentioned in my first post, the resistance range of the MCOR is not a perfect match for the Alltrax throttle range. The modified throttle map you installed (clubcar3.hex?), makes the last 10% of throttle be considered 100%, so You actually get even less usable throttle range, meaning less granular speed increase per amount of pedal travel.
Reducing the throttle up rate reduces how fast the controller ramps up the current to the motor, but the reason that is necessary is because when using an MCOR, there is a very "coarse" increase in speed per pedal travel range at low speed.
This post shows a graph that illustrates the issue:
Alltrax controller - CC precedent - very annoying
Post #31 on that same thread shows how to build an adapter to "convert" the range.
Since You were so close to max at 97%, that circuit may allow you to go 100% without the custom throttle map file so You can try the other throttle curves Alltrax offers.


2) Charging Problem:
I noticed the amateur crimp job on that new 2ga cable on your motor, that leads me to speculate that perhaps the shop also neglected to run the cable thru the OBC (assuming you are using the OBC to control the charge).
You should have a single cable on the pack negative that goes thru the OBC. They should have installed a 5/16 "threaded stud" and used 2 cables, one for each side of the stud. It is possible to squeeze some cables thru that hole, but you need to be careful not to damage the Hall effect sensor inside the OBC.

This is typically a result of not using a voltage reducer. Are your light hooked up straight to the batteries? If so that's your problem and it will always dim under a heavy load draw.

A voltage reducer will regulate the current and make sure your light are always getting consistent juice.

Curious if you know the motor model #.
