| FAST RPM Module Installation,
In no time the flash process will complete and your unit
is ready to start logging RPM.
To confirm the firmware was updated you can repower the
unit and the initial screen should show v1.3 in the lower
Bring the FAST unit back to your vehicle and connect the
RPM module. The module simply goes in-line between the
FAST unit and the existing wideband cable.
Plug the wideband cable into the RPM module and the gray
cable out of the RPM module into the FAST unit. The connectors
are male/female so there is no way to get them connected
The kit comes with two ways to capture an RPM signal.
The preferred method is to tap into a tach output on your
ignition box or distributor.
Plug the 3.5mm jack side of the cable into the RPM module
and the spade connector into your MSD box or similar tach
The other method is to use the supplied inductive clamp.
This method is only recommended for temporary logging
as the clamp can work its way loose. The signal from inductive
clamps are more susceptible to interferene as well. Clamp
to the coil wire or an injector wire.
Power up your vehicle and FAST unit. You'll see the RPM
display at the bottom of the display. Use the calibrate
button to cycle through until you see the unit register
the correct rpm.
A new and useful feature in the firmware is to
set a rpm trigger point for logging. When the engine hits
the desired rpm, and if you have previously activated
logging, the log recording will initiate. It will continue
until you manually cease the logging.
FASTView Log Analysis Software
the original FAST unit the only way to make use of the logged
data was to play it back, in real speed, on screen. This was
obviously very limiting, as you had no way to study the data
and assess particular data points. With the release of FASTView
the logfile can now be transferred to your PC for detailed
FASTView is a free download from the FAST website. Once installed,
you can use the same USB/Serial cable and power adapter to
connect the FAST unit to your PC and transfer log files from
the unit to your PC for analysis.
software has a dashboard style playback screen, or a plot
screen where you can view point by point air-fuel ratios against
rpm. Most gearheads will testify this is where the real tuning
value is. Here you can overlay two logfiles and compare the
effects of tuning changes, for instance. Another very handy
feature is the Excel output file, should you want to perform
even greater statistical analysis on your log files.
