Oh, batteries are 2 year old AGM ---

> 3.5 hp stock. Hmmm… Because of this- I suspect you probably will not go much faster. I would think about upgrading your motor first. Try this- Unplug your speed sensor (the 3 wire triangle Deutch connector coming out the end of your motor) and take your car for a hot lap around the block. Does your car feel faster? (Your speed display will not work). Double check with a GPS app previously loaded onto your phone. Normally, the controller gets upset and throws a Code 81 if it loses the Tach Signal from the motor. I have noticed some of the old cars don’t really care. See if yours will run. It may not go any faster, but if you have a slight hill in your area you may notice it doesn’t hold back like it used to. ---

Checked gps speed with and without speedometer plugged in. Absolutely no difference. I guess I’ll save the MM for when I upgrade the motor. Will do brakes and wheels first. Found a used R4F 7.5hp motor. Can I do a controller reprogram or do I need to send it somewhere? Also found the source of the deceleration noise and vibration-differential was 12oz low on gear lube. Topped it to overflow on fill plug with 89-90. What a difference!!! ---

It is not 100% necessary to reprogram your controller when doing a motor swap. A few tweaks can be usually be done to the controller to get a few more clicks out of the new motor. R4F does offer the programming service if you buy one of their motors from them but you need to send your controller in for the tweaks. You might be able to find the old software and programming cable required to do it yourself but there is a bit of a learning curve and time investment for something you will only be doing once. Depending on your location there may be someone in your area that can do it for you. ---

Hi, I know I’m late to the GEM game but I picked up a fairly healthy 2001 e825. I was hoping there was still a way to get a magic magnet but haven’t found any online. ---

How can i order a magic magnet? Will it work on my 2007 Gem cart? Any idea what the speed improvement potentially could be. Thank you ---

The speed will be whatever the car can do without a limiter. $150 PayPal to barbjb@acegroup.cc ---

@cfocats - It would also be a good time to make sure your battery pack is up to the task. Just like a 4bbl carb on a big block v8, mashing the loud pedal and going faster requires more energy. Use it wisely. Yes, it is hella fun, but your range suffers. ---

recieved the MM, and noticed a dip switch inside, but no instructions as what the dip switch does. thanks for fast shipping btw ---

That is for custom tweaking if needed later. Leave it for now. The most common setting is 1+3 to ON. All you need right now is plug it in and go. Note that your dash display will be reading a little slow (if set to mph). A quick press of the Trip button will change bottom numbers. Press it until the ODO is displayed. Then a LONG press will change the display from mph to kph. Now the number displayed will be close to the actual speed you are traveling in mph. (ignore that kph label). ---

yes, noticed that mph tops out at 20 now instead of 26 like b4 will make change and see if better, ---

made the change and now i get 31 on the flat with fully charged batteries which is plenty, but we live in hilly area and i noticed that that going down hill without the pedal it does not run away, seems to be slower than tbefore when it would hit 25 and limiter would kick in ---

Hello, I have a 2009 gem e4 and just upgraded it to a lithium battery. Massive upgrade btw. Anyways. This Gem is my daily driver as I can’t drive long distances (narcolepsy). I was wondering how much of a speed increase you get with the MM if I have the lithium batteries also? Thanks your your input!
