Introduction
MyChron 3 660 is the new data acquisition system that AIM designed and developed only and
expressly for Jr Drag Racers; a small, complete and high tech data acquisition system.
MyChron 3 660 stores run and not laps; each run includes a few seconds before your launch,
your pass and your coast down.
Its configurable RPM graphic display, the two separate temperature inputs (cylinder head and
exhaust gas), the magneto resistive speed sensor, several properly engineered firmware features
and Drag Analyzer, the completely new data analysis software, make MyChron 3 660 the best
tool to monitor the dragster's engine as well as dragster and driver performances.
MyChron 3 660 records RPM, 2 temperature inputs and speed at a sampling rate of 20 Hertz per
channel (20 times per second). This data can be retrieved at a later stage for analysis.
The logger records and displays the following parameters:
Moreover, MyChron 3 660, calculates through its software and displays
All these parameters are legal following NHRA rules.
Data is stored in the 192 kbyte internal EEPROM memory that can record up to 50 runs. Stored
data are downloadable to a PC through an USB cable You find as stock in the packaging of Your
MyChron 3 660.
MyChron 3 660 is powered by an internal source, so You need 2 AAA Alkaline batteries to
power it.
