The DC RPM-iBOX2 picks up pulsed current in plug wires, coil-over-plug wires, as well as injector wires. The RPM iBox 2 also measures boost and has a thermocouple. MAP (BOOST) Analog Output:
The DC-RPM-iBOX2 uses a NXP/ Freescale Semiconductor, MPX-5700AP integrated silicon
0-700 kPA (0-101.5 psi ) pressure sensor to measure vacuum/boost. Hence, it is capable of measuring boost up to approximately 87 psi.
The unit outputs a 0-5 VDC signal between PIN 9 (MAP Signal+) and PIN 5 (Ground/Signal-) of the DB9 connector. This can be directly plugged into an analog input of the DC-Controller.
The following is the transfer function to scale the voltage output vs the pressure differential:
Vout = 5.0 x (0.0012858 x P + 0.04 )
Where Vout = Output DC Voltage & P = Differential Pressure in kPa
Note: Transfer function temperature range 0-85°C
To configure the MAP/Boost to be used with your Quantum Dynocom software please refer to the Analog Input section of the online documentation for Quantum.
Thermocouple Analog Output:
The DC-RPM-iBOX2 can use any K-Type thermocouple that has a polarized sub-miniature thermocouple connector.
The unit outputs a 0-5VDC signal between PIN 8 (Thermocouple Signal+) and PIN 5 (Ground/Signal-) of the DB9 connector. This can be directly plugged into an analog input of the DC-Controller.
The following is the voltage output vs temperature:
Vout = 0V to 5VDC over range of K-Type sensor used.
