Default MCOR rant!

Someone should create an aftermarket replacement for the mcor! Replaced the unit in February with a new MCOR4, didn’t use the car much from June-September and low and behold, bad MCOR. This time it was super jerky at low speed and wouldn’t let me hold a slower speed/throttle. At full throttle it was fine once up to speed.

Just replaced, all good again. Just ranting that we don’t have a better option. I know the MCOR4 has had less failure, but 7 months to failure shouldn’t be possible IMO. I think someone super awesome like Sergio or Tahoedog should create a better option :)

There most certainly is...I put a Chinese version in a friends cart at less than half the price and it has been going strong for over a year...I was skeptical at first but it is working fine so far...Pick your country China or the CC version at full price made in Mexico..

Interesting, from past posts it looks as if the Chinese version fails even faster. A lot is dependent on use, if you use your car consistently there seems to be less failures...

I also didn’t see the china version for half the price as Dave sells them for right under $100 shipped. I saw the China version for $70, is there a cheaper place?

I guess it depends on what version you want...A Chinese mcor1 knockoff sells for around 50 bucks...All I am telling you is that I installed one in a friends cart who plays 18 holes of golf 4 to 5 times a week and it has lasted over a year....Maybe sh** luck I have no idea...Ask ScottyB...A poor design no matter what you do...

Tru dat. The MCOR4 is the better design.
I have a 2014 Precedent that needs one. GRRRRRRR
Club Car is listening - They ditched the OBC. Now get a inductive throttle system and improve the ride and you get ..... uhm, well... an Ezgo

I'M thinking that the ezgo its isn't any more reliable than an mcor..They seem to also have a pretty good failure rate..

Any of You guys having the "jerky" throttle (and an XCT Controller), see if you can test the throttle signal using the trick in this post:

If You see the fluctuation, test if the accelerator pedal "arm" is what is twisting and triggering the jerk.

You need to learn how to repair the MCOR4. The problem is the wiper not making good contact. Take it apart clean and bend the wiper arm up slightly. Reassemble then drive trouble free for about 6 months then repeat the process when it goes bad again.

Here we go again. I'm thinking - respectively, of course. You have no idea what your talking about.
The ITS is susceptible to 1 common problem which is signal interference due to the presents of water in the tunnel which is a zero cost fix with a blow dryer borrowed from your wife.
Any other problem with the ITS is signal wire failure or controller failure, and not really the fault of the ITS

Scottyb, TD and Sergio,

Could this be used to replace the go pedal on a CC with the XCT programmed for 0 to 5 Volts?

I realize it would require a 5 volt DC supply, possibly a 12 volt to 5 volt reducer.

And it would not release the brake....

But could it be done effectively?

If you tell me to get lost, I'll understand!

http://vi.vipr.ebaydesc.com/ws/eBayI...1&secureDesc=0

I just notice the input voltage is 36 to 80 VDC, so it must generate the 5V output based on that.
