Hi Gary ( GM Canada)
this was the thread I was prompting....i know the internal will always have less amps than the external, but on my external imscared to use the usb cable, as clearly using it, something is limiting the controller after the USB cable is usedou
anything you can do with Tom to get an inside scoop ??
Since you are kind of "holding my feet to the fire" on this one, I have looked into this and here is what I have found out. Some is theory and some is fact, but I believe all of it to be true. When the MP1's came out quite a few of them died simply because as we all suspected the controllers got to hot inside the case. That being said there are a lot more people still riding around on MP1's then the failures we have all seen in this forum. I would say from my sales and number of failures I had on MP1 the ratio is well over 25 good ones to one failure and the numbers are probably better than that. Then Came MP2, wheel centered and programmable controller. Actually I can’t even recall if the first mp2’s were programmable(age is a terrible thing). Seems to me everyone was booting around having a great time. Then people started using the usb cables and suddenly losing amps. As more MP2’s came from the factory the controllers were pulled back to stop the failures. Probably as most of us feel pulled back to far. I suspect in the early stages of the pull back a lot of motors went out without being set with the USB. These motors were as powerful as the originals. Then once the USB cable was used the amps were reduced.
I experienced this myself. I first had an MP2 on the back of my bike when it was a single motor rear wheel drive. On my way to work full tilt uphill it would kick out by overheat protection after about 10k. It would take 5-6 minutes to cool off and then go again. After about a week I used the usb cable to try and cut back the power a bit to stop this cutout. I discovered it was set at 24 volts. So I set it at 48 volts and whamo, less power. I then set it at 24 volts and the power was back. Not as much as there was at first though. Some people get there power back going back to 24 volts and some do not. I don’t know why. I still continued to use it to go to work and it was fine but since I always wanted to go dual drive I did it and never looked back.
The word from Philip is they are working on this issue and improvements are on the way. I cannot elaborate any further than that. What I can say is in my short time with GM I have seen products improve, new products released, more improvements, more new products, etc. There is no doubt more of this is on the way.
