There is a group of enthusiasts who have developed open source firmware for the TSDZ2. Installing this firmware is said to allow expanded control of the operating parameters for better performance. I have not availed myself of this resource but it sounds intriguing. I purchased the kit from EcoCycles in Nashville, TN. This vendor does offer the open source firmware pre-installed as well as a lot of support for doing it yourself.
Hi "Moe"

I contacted Dave at Eco Cycles and we discussed the options and services they provide for the TSDZ2. I'm planning on ordering the system with the 52v updates and battery this month. I hope to be using the bike in March.

Thanks for the tip!
