Page 13
The first page is filled with some
of the most common, basic engine
parameters, from temperatures &
ignition advance, to fuel trims &
O2 sensor values.
The second page is configured for
just ignition voltage. This can be
useful to determine the state of
health of your battery. Turn the
key on, start scanning this page,
then start the car. Then click the
“Info” button to see the minimum
voltage that occurred while
cranking the engine over. If it’s
less than 9.5V, your battery may
be on its way out.
This page shows how injector duty
cycle is monitored. First you
configure RPM and the injector
pulse width, then the IDC1
parameter calculates the duty
cycle. You can use IDC1 & IDC2
to see if your fuel injectors are
being over-worked. Scan this
page & do a wide-open-throttle
run, then click the “Info” button to
see how high your duty cycle
went. If it’s over 90%, your
injectors may need upgrading.
Page 4 contains some fuel-specific
parameters. FTC is the fuel trim
cell number, followed by O2
voltages, short & long-term fuel
trims, and closed-loop status.
