G-TECH / Pro Competition User Guide, Release 3.1
If your vehicle rev limiter kicks in early while stopped, you will
need to calibrate your RPMs while moving in gear. In this
case, you should have assistance from a passenger.
Vehicles with automatic transmissions might need to be
placed in first gear to keep the transmission from upshifting
during the High RPM calibration.
Some vehicles have a very faint RPM signal. If you have per-
formed an RPM calibration but the G-tech tachometer does
not accurately represent your RPMs, your vehicle might fall
into this category.
On these vehicles, you may have better results by turning on
some of your electrical systems (such as the headlights,
defroster, or fan) during the calibration process. If you do this,
however, it often means you should keep these systems
powered when using the G-tech as well.
Another point of note: with many vehicles, the RPM signal is
very weak below 1000 RPMs (even 1500 RPM on some vehi-
cles). This means that when your vehicle is at low RPMs, the
G-tech may register the default value of 750. This is normal
behavior.
During the RPM calibration process, the G-tech suggests two
RPM values to use (e.g., 4000 RPM and 2000 RPM). These
suggestions are based on what you input for your vehicle red-
line.
In all but a few cases, the suggested RPM values will provide a
good RPM calibration. If you are not pleased with how well
the G-tech is measuring RPMs after a calibration, the G-tech
will allow you to change the two RPM calibration points.
For example, for a vehicle with a redline of 6500 RPM, the G-
tech may suggest revving to 4000 RPM for the high value, but
you are free to change this number to a larger number, like
6000 RPMs, during the calibration process.
For example, during RPM calibration, the first screen may
come up as such:
If you would like to calibrate at 6000 RPMs instead of 4000
RPMs, just press
twice to change the “4000” to a “6000”,
and then rev your engine to 6000 RPMs and press
.
