Pro-M DUO - Dual Mass Air Meter Module
From the creators of the Slot Style Sensor, Pro-M 80, Pro-M Wave and the award winning Mass-Flo EFI system comes the PRO-M DUO
It is not just a simple voltage adder. This module allows you to use two meters that are appropriately calibrated for the amount of air flow that will pass through each meter. This is important, because it allows you to use two meters that will each range in voltage from 0 to 5 volts, utilizing their full resolution, and still provide the processor with a 0 to 5 volt signal!
In other words the PRO-M DUO will take the signals from two mass air flow sensors, each at full resolution, process those two 0 to 5 volt signals, and output a voltage ranging from 0 to 5 volts.
The PRO-M DUO has three individual harnesses, each exiting a central control module:
Harness (1) has four wires (12vdc, chassis ground, signal ground, and signal) and is meant to be connected to mass air sensor number one.
Harness (2) has four wires (12vdc, chassis ground, signal ground, and signal) and is meant to be connected to mass air sensor number two.
Harness (3) has four wires (12vdc, chassis ground, signal ground, and signal) and is meant to be connected to the vehicles processor, via the vehicles existing mass air sensor harness connector.
In addition, the central controller includes an adjustable potentiometer that allows the user to fine tune the output signal. The controller is potted, and therefore is suitable for mounting under the hood.
The PRO-M DUO can be ordered by itself, or as part of a package, with two Pro-M mass air flow sensors.
