Sergio brought up a good point about having to upgrade to a different field map. I emailed Alltrax this question.

Quote:
I have a Alltrax DCX500IQ combined with a AMD 7144 7HP motor on a IQ model Club Car. According to the software it is using Field Map 6. Can you confirm that this is correct field map for this combination. If not can you send the correct map.
His answer was.

Quote:
John,

The following map is the better one to use with that motor.
Save the file to your desktop.
Double click the file and a new window will appear.
Select the "Extract all" option on the left hand side.
When prompted for a location to unzip the file, select your desktop.
Start ControllerPro as normal.
Under tools, select "Upgrade"
A new window will open and ask for a location for a file.
Select the .hex and hit "open"
Wait 30 seconds and then it will be done
If anyone wants a copy of the hex file let me know. Been busy today so I haven't updated the firmware yet.

jj - do you find that the less expensive AMD 7144 7 hp @ 5106 rpm gives you the torque you need on the hills where you live? It would be nice to have the speed and still have enough torque for rolling hills.

Does a regular serial port connector plug in where the harness is attached to upload program changes to the DCX? If so will an old laptop with XP work of does the computer need to be upgraded to Windows 7 or higher?

I went with the 7144 because first it was 7hp and I needed the extra HP for the hills around my neighborhood. And it was still in the range (<25 mph) to keep me street legal. The route that I take shopping has one good size hill. With the PQ I took the hill at 14mph. With the AMD it will do 20. Around town I can just blend in because it now has the speed and acceleration of a ICE vehicle. The only time people blow their horn at me is to wave, and not with one finger. BSEG.

Not quite sure if I understand your last question, but the software is old (2006) so it will run on XP and if you have a serial port on your laptop that would be an added bonus.

I don't understand the pricing of the motors. It doesn't follow the HP rating of the motors. My guess would be the amount of copper used in the windings or the popularity of the motor.

I still haven't installed the new HEX file but I'll let you know if there are any big changes. Suppose to be cold here all week so I don't know when I'll get a chance.

jj - The AMD 7144 7 hp @ 5106 rpm was recommended to me along with the AMD 7177 5 hp @ 2740 rpm, when I ordered my controller. The price I was quoted was less for the 7144. When I used the speed calculator the 7144 would increase my speed but I assumed the 7177 with lower rpm would give more torque but even @ 2 more hp would not increase my speed, based on rpm. If the 7144 gives you enough torque where you live, I think it would be right for me. I feel a need for speed!

You said it earlier or at least implied it. The motors that develop max HP at lower RPM's are torque motors and the ones that develop max HP at higher rpm's are for speed. Let the motor take care of the speed and the controller take care of the torque. All in all I'm happy with my setup (DCX500IQ and AMD 7144). I still have one problem left. Intermittently I get a rough takeoff. I think I am getting torque bumps and I'm hoping the new field map fixes them. I think you will be happy with the 7144.

Almost forgot another reason I went with the AMD was because it has the speed sensor built in. That way if i have to I can go back to the Curtis controller if for no other reason other than troubleshooting problems.

jj - Please share your results after you load the program and adjust.

Lakebit I still hadn't been able to get a good test drive out of my cart due to cold weather and snow. I did get some new tires on it, upgraded to a DPI charger and remounted the Alltrax DCX500. Now just waiting on some nice weather. Here are some pictures of the Alltrax and solenoid mounting.

Looks good JJ

I see you removed your OBC as you have a DPI charger and mounted your DCX500 horizontally without interference.

I still use my PowerDrive 3 Lester Electric charger and OBC. I considered moving the OBC to the battery compartment side of the mounting plate like Sergio suggested, however I found a 12" x 12" piece of aluminum plate at Home Depot the same thickness as the OBC plate, so I removed the screw from the OBC mounting plate on the passenger side and cut the plate to shim under the rest of the controller which allowed me to mount my controller without using spacers or moving the OBC from it's factory location.

I still want to here about your program change when the weather warms up and you have a chance to checkout the performance

Hey guys we have spent a lot of time and money doing r&d on motor and controller packages designed specifically for the Precedent and as an end result we have put together some amazing setups.

We don't want to step on anyone's toes so we aren't going to go into to much detail other then saying if you want a controller that works seamlessly with the Precedent we would suggest the Curtis 1268, it has endless adjustment capabilities and we use it exclusively in our performance packages. One of our favourite things about the controller is how it integrates into the stock Precedent system, you get a stock feeling on the bottom end and it's smooth right through its entire range.

We have 3 levels of performance packages and we use the controller on two of them, the first level of our performance package uses just our SC Carts Speedster motor, then our next level is our Speedster plus package, the plus is the controller and finally we have our Torkster package which is a torque motor that we combine with the controller, which is amazing.

Anyways just thought we would add this information in for anyone who is looking at different controller options!

All the best and have a great weekend.

Do you build your own motors or is it third party?
