I have a 2005 Gem with a bad controller. I would like to do a speed upgrade (at least 35) while I am at it. What seems to be working well. I see guys that offer to rebuild controllers and 7.5hp motors. Already have 195-14 tires and wheels and from what I read 10.35 : 1 gears. Has anyone had any luck at this?
Thanks for any help.
Which controller?
What problem?
T3 and I am pretty sure it is toast. I followed the flow chart in the service manual pretty close. I am just looking for folks that have made this up grade to get their opinion of the results.
Yeah - as long as your controller is bad any way upgrade to a T4. The T3 is pretty limited.
For 35MPH you will have to up grade your motor to a RFF. motor.
At 35 MPH with your setup you will be turning 5500+ RPM. A stock motor doesn’t like over 5000 RPM for very long. If you stay at 30 MPH it should live forever.
Thanks for the post. Is it a big deal to change to a T4. And point me toward an RFF motor that is new to me. Was looking at a blue motor but!
DandD builds Ride for Fun And MZ Motor Sports (Blue and Black) motors.
What is an RFF motor. is The D&D motor a good setup.
Ride For Fun is the dealer D&D is the manufacturer
What is involved in changing from the T3 to a T4 controller. Are they a direct replacement
I think there is someone in FL that can flash program the T4. Any Idea who it is?
To what effect? Correct speedometer?
I’m looking for a junk T3 if you end up with one.
My 2010 5hp 12/1 EL runs 35mph with 24" tires and MM. Lead and T4.
Motor may not last. Not an issue for me.
Can’t be worse than running 100 volts in my E4 7hp.
See signature…
Not sure about the T3 vs T4 issue, just trying to learn a little. I was told that the T4 could replace the T3 and had more turning chooses and understand I don’t know this for sure that is why I am asking you guys.:noidea:
I believe you are correct, that’s why I’d like to have a T3. To look for work arounds.
Some have issues with speed. http://www.electricforum.com/cars/gem-nevs-forum/9953-gem-wont-go-over-29-mph.html
Some not. http://www.electricforum.com/cars/gem-nevs-forum/9976-2005-build-update.html
Hi
if you not get over 29 did you try to change software in your T3 ?
try to change from GL7L to GL8L
An explanation on how to do that might be a good idea. Also a reason why.
This is new information not posted before. Educate us as to what this is and how it might help us please.

Firmware?
Is it available?
I can program a t4 to do what ever you would like .
The man to see and he’s in Florida… very reasonable fee.
