Then, use the arrows to make your choice, and press Select :
In addition, a coupled input may need to have an internal threshold value changed. This
threshold value is used by the GPX's internal circuitry for determining a valid signal. For coupled
RPM capture, you may need to adjust both the threshold, and the number of wraps around the
spark plug wire, to obtain a reliable RPM reading.
If you have more than one RPM input connected (for example, an RPM input on one of the digital
inputs, and a inductively coupled [wire-wrap] connection), the GPX will report the the RPM from
the digital input as the correct RPM. In other words, the digital input has precedence over the
coupled input.
1.7.3.2 Throttle Position
Throttle position needs two points for calibration -- the 0% throttle position (no throttle applied)
and the 100% throttle position (throttle completely applied). On most vehicles, you should do
this calibration while the vehicle is turned on, but not running (it might not be a good idea to run
full throttle in neutral!).
1.7.3.3 Temperature
Most vehicle temperature sensor are thermistors (resistors which vary resistance depending on
their temperature). These sensors need to be calibrated within the GPX at several different
temperatures in order for them to display an accurate temperature reading.
The GPX allows you to enter up to 10 different calibration points for each temperature input. If
you make a mistake, you can either delete all calibration points, or you can delete one of the
