Strongest:  Most advanced software functions
Simplest:  Built-in electronic switch saves chassis space
Easiest:  10 Pre-set profiles for Plug and Play
Most Reliable:  Innovative heat dissipation structure

XERUN-120A-V3.1 has 3 color options:
Blue edition: PN=81020340
Black edition: PN=81020350
Red edition: PN=81020360

Advantages of XERUN-120A-V3.1 speedo
★ Aluminum bottom case improves the heat dissipation (The previous V3 speedo uses plastic bottom case);
★ Improved heat-sink with 1mm gap between the cooling fan allows more air flow to reduce the temperature of speedo;
★ Improved dust-proof design. Rubber rings are applied at the sensor port and the program port;
★ Aluminum screws of cooling fan look better and more professional;
★ Improved electronic switch has stronger current endurance to be more reliable;
★ New firmware allows driver to adjust the throttle neutral range, and solves the "turbo lost in high temperature" problem in the previous version firmware.
