in bowls.
NOTE:
Calibration is exactly the same on engines with a DPM Module and those without.
Compensation Mode
1. Air jet
2. Needle jet air inlet
Three conditions must be met for the compensation mode to operate:
1. The engine must operate at over 3000 RPM. Signal received by the GRAY/GREEN wire.
2. The air temperature must exceed -20°C (-4°F).
3. The atmospheric pressure must be lower than 1000 mbar.
The system brings all 3 carburetor bowls under vacuum in order to make the air/fuel mixture leaner. The
required vacuum is produced within the needle jet air inlet.
