Re: 2009 CC Precedent - Time for Upgrades
I went with the Alltrax XCT500 and it's great. I've got it, a 400amp HD solenoid and 2AWG cables installed. There were no notable hiccups during installation other than it being a tight fit. I charged the batteries overnight and ended up with a 51.0 volt pack this morning. The initial torque is much, much better than before, no comparison. But, the top end speed doesn't seem to be there. I topped out at 18.8 going down a slight hill and about 15.5 on a flat surface (flat ground). I'll check my air pressures after work to make sure they are where they are supposed to be. Other than that, does this sound normal for a cart with upgraded electronics and a stock motor?

Re: 2009 CC Precedent - Time for Upgrades
What field map are you using?
What did you set the max rpm to? |

Re: 2009 CC Precedent - Time for Upgrades
Right now I'm using the field map that ScottyB setup for me. I'll check it out and see what the max rpms are set at.

Re: 2009 CC Precedent - Time for Upgrades
It might be the generic map. Check your motor part number and call Alltrax.

Re: 2009 CC Precedent - Time for Upgrades
Ok. I'll check the model number this evening after work as well as the Max RPM setting. I did turn on logging for a minute this morning. Under the 'speed' column, it showed it in the upper 2900's a lot with it going over 3000 only 1 time (304.

Re: 2009 CC Precedent - Time for Upgrades
If You look at the top of that log file, you have the controller model #, s/n and Field Map used.
I started with the UNIMAP-V1 and noticed a similar issue with top speed and what it seemed like a lack of HP. I changed it to the EJ4-4001-V9, which is the latest for the stock ADC motor as of last week and it had a very noticeable impact on top speed and the motor is definitely developing more HP based on the armature current going up. |

Re: 2009 CC Precedent - Time for Upgrades
Call Altrax (number on their website) and they will email you the EJ4-4001-V9 file for the stock motor right away.
I think the UNIMAP-V1 is just a little "too safe"... |
