I'm considering buying an '08 Zenn that has an AC motor. My understanding is that the controller (Curtis?) can be modified to remove the 25mph restriction. Is that right? If so, will this affect the AC motor's capacity, performance and/or longevity?
Are there other things that I should know about performing this modification in terms of how it will affect the car's performance? Would this modification cause other special maintenance issues?
Zenn. If they haven't changed their ways, then the motor the car comes with is JUST BIG ENOUGH to power their cars at 25 mph.
Yes, you can program the controller to allow the motor to call for more power than the manufacturer intended. This is something we Washingtonians and Montanazoids have been doing for years now...but we've also learned in the process that you really need a bigger motor; )
