If your car has no usable wheel speed sensor, the GPS Speed Input Module (HT-011310) is an easy way to get vehicle speed onto a Racepak or Haltech IQ3 Street dash. It outputs a speed signal the dash reads just like a pulsed speed sensor.
| Dash setting | Value |
|---|---|
| Where the GPS signal wire lands | Pin 32 on the dash |
| Pull-up resistor | Off |
| Input sensor type | HE RPM Input |
| Value B (raw data) | 24 |
Once it's configured, drive at a steady speed and compare the dash against a phone GPS app. Remember the module needs a clear view of the sky, so mount it where the roof or dash top isn't blocking it. If speed reads zero, check pin 32 and that the pull-up is off.
