Speedometer Sensor Interface
The IQ3 Street Dash requires an electrical speedometer output signal from the transmission.
There are two different types of speedometer sender input settings, Variable Reluctance (Zero
Crossing Sine Wave) and Hall Effect. The dash is defaulted for Variable Reluctance (two wire)
sensor type. If the sender you are using has a Hall Effect output you will need to change the sensor
type setting in the dash. See section Setup Mode for programming instructions. The table below
shows the different speed sensors supported.

Speedometer Calibration:
To facilitate ease of calibrating the speed settings of the IQ3 Street Dash, the initial temporary use of a
standalone personal GPS unit or GPS via cell phone to show current speed is required.
The speedometer, odometer and trip odometer may not read correctly until you select the
appropriate speed sensor type, connect dash to a sensor and perform a calibration.
To calibrate the speed follow the below procedure.
1.
Turn on the dash and enter setup mode 2 by entering a MEDIUM press on the button 2
2.
The Dash will display SETUP 2?
3.
Confirm you wish to enter setup 2 by pressing button 1 for SHORT press
4.
The dash will now display CALIBRATE SPEED N
5.
Enter a short press Button 2 to toggle N to Y to prepare for the next step, CALIBRATE
SPEED Y will be displayed
6.
Safely drive vehicle at a steady rate of 40 MPH (or 40 KPH if units are to be in metric). Once
at 40, enter a Short Press on Button 1 to set speed calibration value.
7.
Dash will then record the correct pulse count from the connected sensor for 40 mph/kph,
and will start to display to correct speed on the LCD as well as advance to the CALIBRATE
GEAR setting.
a.
If the vehicle is equipped with an automatic transmission enter a short press on
Button 1 to save and exit speed calibration settings.
b.
If the vehicle is equipped with a manual transmission, you now can calibrate the
gear position indictor for each gear by a short press on Button 2 to change value to
Y and follow the Gear Indicator calibration instructions starting at step 5.
