This Bus Interface Module is designed to read engine information from specific MEGASQUIRT EFI kits. These kits 
include: Megasquirt-2, Microsquirt, MSPNP2, Microsquirt-module based ECUs with firmware MS2/Extra 3.4.x only, 
Megasquirt-3, MS3-Pro, MS3-Gold, MSPNP-Pro, MS3-Pro-module based ECUs with firmware MS3 1.4.x only.

 

The module is 

connected to the MEGA through the CAN-bus CAN H and CAN L on the MEGASQUIRT harness.  
 
There are two interface (I/O) ports on the module.  Either one can be connected to the gauge system or to another 
module, allowing several units to be daisy chained together. Do not connect the I/O port to anything other than a Dakota 
Digital gauge or BIM. Do not mount the module in the engine compartment; it should be mounted in interior of the vehicle. 
 
The information that is available from the unit depends on the EFI module programming and add-ons. The possible values 
are: engine RPM, vehicle speed, engine coolant temperature, intake/manifold air temperature, oil pressure, fuel pressure, 
average A/F ratio and boost. 

 
Available readings:  RPM, engine temp, intake/manifold temp, fuel pressure, A/F ratio, vehicle speed, oil 
pressure, boost/vacuum
