STOV-002 to AMS-1000 boost controller:
The Stage input for the AMS-1000 can be configured for either ground or +12v. It can be pulsed input
or an analog voltage input.
To connect the STOV-002 to the AMS-1000 we recommend using analog voltage input setting and the
analog voltage output from our MPH switch (Yellow voltage out wire).
The voltage out data from the STOV-002 is not modified by any of the switch settings. The pulse per
mile signal into the STOV-002 from your ECM or other device needs to be calibrated correctly. If
this data is correct, then the voltage output from the STOV-002 will also be correct. Analog volt-
age output is 0-5 volt 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 rela-
tionship between speed and voltage). The analog voltage output function operates the same in all
modes.
If your input signal into the STOV-002 is not calibrated correctly you can scale the STOV-002 signal to
make the readings still work in the AMS-1000. You can easily check to see if the STOV-002 signal
is calibrated correctly using a volt meter on the yellow signal output wire.
In order to cover a wide voltage range in analog mode all 6 stages need to be turned on. Even if the
user sets 5 of the same boost level. Each stage has a +/-V adjustable setting. The AMS-1000 can be
programmed to not activate until 1.5 volts for the first stage if desired. If the vehicle will never see
255mph then the maximum speed can be used to determine the working voltage range. The range/
gap is adjustable for each stage.
For example
· Stage 1 = Target Voltage = .5 v, range +/-.4v
· Stage 2 = Target voltage = 1.3v, range +/-.4v
· Stage 3 = Target voltage = 2.1v, range +/-.4v
· Stage 4 = Target voltage = 2.9v, range +/-.4v
· Stage 5 = Target voltage = 3.7v, range +/-.4v
So in the example ranges provided above the stage entry speeds would be 5 mph, 45 mph, 85 mph, 125
mph, 165 mph and 205 mph (see table below).

If the voltage does not fall within a programmed range for a stage the activation turns off.
