Introduction
MyChron 3 Visor represents the new generation of “High-technology” Aim
data acquisition systems for car racing.
MyChron 3 Visor samples and displays speed and lap (split) times.
Moreover it can be interfaced with the engine’s ECU using a Serial / CAN
cable connected to the POWER/COM input to sample all the channels
acquired from the ECU.
