Speedo
The speedo input measures pulses from a hall sensor or other pulse sensor (usually on the front wheel). The pulse
amplitude needs to be between at least 0 and 5V, 0 and 12V is fine as the input is protected. The system increment
the disatance travelled and as a result the calculated speed on each pulse.
Tacho
The Tacho input is designed to work with 12C -> Ov ( or vices versa) pulses consistent with the trigger pulses used to
drive 12V ignition coils. The system measures the interval between pulses – so dwell of the pulse does not affect the
reading.
For a CDI system – either a 12V compatible output is needed or a CDI tacho adaptor to convert the CDI pulse to a
12V compatible pulse should be used.
Oil Pressure
On most bikes the Oil pressure indication is a simple switch that opens when the oil pressure reaches a certain
threshold – usually between 4 and 7 psi on most bikes. This is interfaced most directly to the oil pressure state
sensor line.
This should be set to – Polarity Normal (true).
Some bikes (notably some Yamahas – have a low oil level light rather than a low oil pressure (FZR)) but the sensing is
the same.
If your bike has an oil pressure sender that actually indicates pressure rather than being a simple switch then this will
normally operate like a resistive sensor between 0 and 100 ohms – If it is connected to an existing oil pressure
display – you will need to work out the values by measurement.
If it is biased from the OBD_Bridge – then it should be a reading of approximately 5.9 adc counts per ohm of
resistance.
The other option is to fit an electronic Piezo sensor – See the Rae-San adaptor.
Tail/ Head Light
Some bikes are equipped with sensors that report on the status of the headlight or taillight bulbs. Usually these are a
12V / OV signal that can be simply interfaces on the state monitoring inputs if desired.
SideStand
Some bikes are equipped with an interlock on the sidestand . Usually these are a 12V / OV signal that can be simply
interfaces on the state monitoring inputs if desired.
Throttle Position Sensor
Many of the bikes with fuel injection use a Throttle position sensor to feed the ECU. These ae usually a resistor based
sensor with an output voltage between 0 and 5V that feeds into the ECU. These should be able to be directly
interfaced to the OBD_Bridge.
For older non-fuel injected bikes – it is possible to rig up a throttle position sensor to input position to the
OBD_bridge. This is only really worth the effort if an O2 meeter is also fitted so that the fuelling can be analysed in
detail.
This can be used by the OBD_Bridge
