M-cor question
Can an MCOR be faulty, but still be able to smoothly accelerate from 0 to full speed?
My cart gets somewhat jerky when I’m steadily going about 20%. |

Re: M-cor question
If you have an IQ motor with a speed sensor that could be bad causing the issue

Re: M-cor question
It’s an EMP motor that was installed a month ago to replace one that had gone out. Before the old motor failed it was doing the same thing of slightly jerking (lightly surging and slowing down) when going at steady slow speeds.

Re: M-cor question
what controller do you have a factory or aftermarket? I didn't have the correct feild map on my alltrax controller and it did what you said.

Re: M-cor question
Trying to find out. I’m not really well-versed with this stuff.
I sent a message to the guy that built it with some of your questions. |

Re: M-cor question
Alright here’s an interesting solution. The builder said it doesn’t have an alltrax controller, so felt it was probably the MCOR. He told me to turn it off, put it in neutral, then press and release the throttle pedal really fast 15+ times.
I did exactly that and it actually fixed the problem. Smooth acceleration. Steady slow speeds with no surging. |

Re: M-cor question
well good but that just tells me that if it happens again you should think about replacing the MCOR

Re: M-cor question
You basically "cleaned" the wiping surface of the MCOR by doing the press and release; it didn't solve the problem but delayed you buying a new MCOR for a bit. Start saving up (Site Sponsors have the good ones)

Re: M-cor question
Yes, that’s what he told me. I went ahead and bought a genuine OEM on eBay for $60.
