Our Dyno Dynamics rolling road measures horsepower and torque at the wheels. From
these figures it can then estimate power and torque figures at the flywheel. AFR
( air fuel ratio ) is monitored and recorded using a wide band lambda sensor. All
power runs are recorded by the dyno allowing us to recall them.
To assess the quality of ignitions systems we use the oscilloscope on our Snap On
Modis machine. Configurable for 1,2,3,4,5,6,8,12, cylinder engines the scope is a
great tool for fault finding and health checking. In digital mode as shown on the
right picture it is excellent at picking up very intermittent misfires. Watching
the spark patterns in real time also gives a good indication if one cylinder is running
leaner than the others.
