Data Recall and Analysis
When a test session has concluded, you are ready for data
recall and analysis.
To enter the data review mode, press MEM, which also marks
the test as being ended. The display will first show the best
lap in the session, as in Figure 3. Again, the best lap
indicated by the
be
to the left of the lap time.
Press the direction keys to move forward or backward through
the lap times. Forward is indicated by >>, backward is
indicated by <<.
To view the maximum channel values for the lap currently on
the display, press the MEM button. You will see the
maximum values for each channel; temp 1, temp 2, speed
and RPM, as in Figure 2.
To view the data logger memory from the display, while
viewing the maximum value screen, press the MEM button.
Immediately you will see the selected lap played back in real
time on the display. The values you will see are speed, RPM
and distance from the beacon. If wheel speed is not present
during the test, as in the MCT/K model, the playback will
display RPM and time. The playback screen is pictured
below.
At the end of the playback, it is possible to scroll through the
recorded data for that lap manually by pressing the direction
keys, forward >> and backward <<.
Installation
You new My-Chron 2 is composed of:
•
Display
, to be mounted to the steering wheel.
•
Junction Box/Data Logger
, to be mounted under the
front fairing.
•
Infrared Receiver
, to be pointed to the beacon set track
side.
•
RPM Pickup
, an inductive sensor, to be attached directly
to the spark plug wire.
•
Temperature Sensor(s),
k-type thermocouple to monitor
specific temperatures.
•
Wheel Speed Sensor/Magnet
, to be mounted to sense
1 wheel speed, typically the front wheel.
Standard on
MCV model, optional on MCT model.
•
Beacon
, or infrared transmitter, to be placed track side to
mark laps.
Display
, the display is designed to be mounted directly to the
steering wheel. The notch on the bottom of the display is
designed to slide under the top bolt of the steering wheel
mount. The top of the display has a narrow piece with 2
notches on the side, which you attach to the forward spoke of
the steering wheel with a tie wrap.
See photo.
Junction Box/Data Logger
, the junction box is designed to
be mounted under the front fairing. We recommend mounting
the box with dual lock Velcro®, not included. The junction
box is where all the input channels connect.
See photo
.
Infrared Receiver
, the receiver must be pointed to the side of
the track where the beacon is placed. The receiver must
have a clear line of sight to the beacon, it will not work
through opaque materials. Race traffic will virtually NEVER
cause a missed lap, the beacon has an extremely powerful
signal which will reflect off anything in its path. The small lens
at the end of the receiver is where the signal is received. The
My-Chron 2 has an approximate 7 second blanking, where it
cannot receive a second signal. We also recommend
mounting the receiver with Velcro, not included, which will
allow you to change for left or right side receiving.
See photo.
RPM Pickup
, the RPM wire should be routed along the
chassis back to the motor area, secured to the chassis in a
few points with electrical tape or tie wraps (when using tie
wraps, be careful not to cut the wire by over tightening).
