2004 Pontiac Grand Prix Comp G:
Single PT series Interceptor scan gauge
We monitor boost, intake air temp, transmission temperature, current gear,
ignition advance, mass air flow frequency, knock retard, etc. We use this
information to tune the car with a third party tuner.
We monitor knock retard with the gauge’s annunciator function. If it exceeds 3
degrees the super-bright LEDs will light.
We can turn the electric fan on/off manually with the gauge, which comes in
handy at the track to cool the engine bay between runs. We also performed a
CASE relearn with the gauge when a new PCM was installed.
