and keep tuning right until you go back to starting point, slow down before
each right turn, and speed up after each right turn, keep steady speed

The guage used for test is DFC-1 digital fuel consumption meter, similar
to MPGuino, directly sampling signal from fuel injectors.  |
I still want to add something into my DCD TEST SCHEDULE -----
To be as accuracy as possible during the test, cruise control must be always
used to maintain the constant speeds. Once the cruise speed is set, it is not
allowed to change and adjust during the whole test group, cancel and resume
will be used to turn the preset speed OFF and ON after and before each
individual test trip. The only limit is the lowest speed of cruise control, which
is around 28 MPH. So for 20 MPH test, the foot must work hard to keep the
speed constant. Who has a better and more steady solution than foot?
because 20 MPH test is important and could save over 10%.
