Unsure which Calibration value to use? Start the engine and see if you get the
lights coming on at 1000, 2000, 3000rpm etc… If the lights are coming on too soon,
increase the calibration. If they are not turning on or you have to rev the RPM too high,
reduce the calibration.
TIPS:
•When you first turn on ignition, it will display battery voltage. This will normally revert to
RPM mode a couple of seconds after the engine has started. To have it in RPM display
mode straight away, press a button to exit battery mode (ONLY before starting the
engine).
•Unless you have an odd cylinder engine, you should not need 1.5, 2.5, 3 or 5.
•If the display flickers with the RPM, reduce the sensitivity first (see previous section
regarding verifying tacho signal connected).
•The Shift-I responds to RPM increasing very quickly. Often it’s considerably faster and
more accurate than the instrument tacho gauge. Which means it may respond before the
gauge needle does. Once a light turns on, the RPM has to drop a certain amount before it
will turn off. This is a configurable feature, quite an important useful one. Later, once you
have the RPM display range set, you won’t notice it.
RPM Set-Points
You can set when the first light turns on (Lower Set-Point), and also when they flash
(Upper Set-Point). The lights in between are automatically calculated. This section
advises how to adjust the set-points.
With ignition on, press and hold the Up button. After a couple of seconds the display
will change. The lights at the right side are used to represent the value of the Upper
RPM set-point. To read the value, count how many times each light flashes. Each
light represent a digit. For example, a value of 12,500rpm would flash the left most
light once (1), the next one twice (2), the third one 5 times (5) and the remaining two
won’t flash (0) & (0). You then have the number 12500. The flash sequence repeats,
so if you miss it the first time, wait for the pause and count again.
Press up or down to increase or decrease the value, then press both buttons at once to
save your changes (or blip the engine over 2,200rpm to save). Setting the lower RPM
set-point is similar, except press and hold the Down button instead. The lights used
are now on the left hand side. More detail on this topic can be found on page 5 of the
User Manual.
You can change these settings while the engine is idle (<2,200rpm), so you can
conveniently make an adjustment and test it. But not while driving!
You will initially only be able to increase/decrease the settings in one thousand
intervals. Once you have the range set roughly where you want it, have a look at page
9 of the User Manual. It will tell you how to change it so you can change this to a finer
resolution, such as increasing and decreasing in steps of 100rpm.
