Introduction

MyChron 4 represents the new philosophy of AIM data acquisition
systems: a data logger with graphical display, easy to configure, easy to
read and, what make sit unique: expansible.
MyChron 4 has a graphical display that allows you to see the graphical
representation of your values, configurable RPM, Optical or Magnetic Lap,
1 Mb internal memory and capacity to record up to 1000 lap with up to 4
splits or 3 hours of sample at a 10Hz sampling frequency for channel, 1
temperature (water, exhaust gas or cylinder head, thermocouple or
Thermoresistor) and the automatic switch-off after 8 minutes of inactivity
(only external power versions).
Moreover MyChron 4 computes forecast lap time and shows times as
absolutes and as difference with the previous lap.
All these potentialities can grow with the optional E-box connected via
CAN to MyChron 4. Thanks to this expansion acquired channels will grow
in a very simple and quick way. the E-box, in fact, has two others
temperature channels and the speed channel (that together with MyChron
4 RPM allows you to compute and show engaged gear number).
The logger shows the following parameters:
The values stocked in 1Mb internal Memory can be downloaded both via
CAN on the 32 Mb Data Key memory (optional) and via USB and Data
