Vehicle speed to voltage conversion function (any Function switch setting):
Analog voltage output is a 0-5 volt DC analog output proportional to speed. Speed range is 0 – 250
MPH (0 volts = 0 MPH, 5 volts = 250 MPH). Analog output will increase at a rate of .02 volt per MPH
(linear relationship between speed and voltage).
The vehicle speed to output voltage ratio/step size is the same in all modes but since different makes
and models of vehicles output different pulse per mile frequencies for a given vehicle speed, the PPM
(or frequency) to voltage output can be changed to between four different of the most common PPM
ranges. These settings are 2000, 4000, 8000 and 10,000 PPM.
Most newer GM vehicles output 4000 PPM from the ECM so for these vehicles you would want to use
the Function switch setting 4, 5, 6 or 7 (depending on what feature you want). The 2005-2006 Pontiac
GTO (E40 ECM) outputs 10,000 PPM so for these vehicles you would want to use Function switch
setting C, D, E or F.
The 0-5 volt Analog and Switched outputs will work simultaneously and either and/or both may be used
at the same time. The ECM/PCM Vehicle Speed Signal (VSS) must be calibrated correctly for this
output to be accurate.
