If that doesn't fix it, I guess the only thing left is to replace the MCOR. Thanks everybody for all the great advise, Greg
You did mention that you put a zip tie in there, to take up space, right? The only other thing to check on the controller is what your throttle curve looks like.

Before you take the MCOR to replace it, check the output with your voltmeter set to OHMs scale.... 5k -0 is the desired readings.. Sounds like you already have 93% of that lol

Hey scottyb, You ask to check the throttle curve. The throttle response is set on linear. How exactly do I go about checking the out put of the mcor? I have a voltmeter, just not sure the proper way to ohm it out. Can you tell me how to go about it. Thanks, Greg

This most likely will not help at all but will help confirm it's not the controller, change the throttle curve to another setting and do the test one more time, if you continue to only see 93% then you know for sure then it's not the controller.

The first few test I ran, the throttle response was on progressive. That's when I was getting 87%. When I went and changed the throttle up and throttle down to 5 I also changed the curve to linear. I got 93% then. This evening when I get home from work I'll change the curve back to progressive and see if it changes anything. Thanks cheapjeep2, Greg

Ok,I went and done the test before work. When I changed the throttle curve from linear back to progress the throttle response went from 93% to 87%. I change to another curve and I still got 87%. I can only get 93% when the throttle is set on linear. So, does this mean that my problem is the controller? I've not called Alltrax yet because I wanted to do these test before I call them.

It could be the controller but I kind of doubt it. Before you do anything else you need to see if you are getting the full range of output/input from the MCOR unit. You need to do as ScottyB suggested and use your volt meter set to OHMS and make sure you are seeing 5K-0 for your throttle.

You can do this on the pins of the MCOR but an easier place to do this is on the IQ adapter at the controller. Set your meter to ohms in a range that handle 5k... And put the leads of your meter on Pins 1 and 2 of the controller. You should see 5k+or- with no throttle and at wide open throttle you should see down around 0.

Reference the pic on where to test.

Yes, that is what I was thinking ~ then you know for sure which unit is at fault

Try it that way first. If no results put it in run and just be careful. That IQ adapter may need power to get the signal to the controller.
