EMIS (Engine Motor Interface System!)

The EMIS (Engine Motor Interface System!) module is the brains of the system. It plugs into the OBD II port and monitors, speed, throttle position, and several other parameters. There are also connections to the brakes and reverse to ensure the system will not engage unless moving forward. The EMIS allows you to set an aggressiveness setting 1-10. The higher the setting the more electrical assist you get but the less the range. I am impressed with the engineering and coding of the EMIS. Unfortunately I just do not believe there is enough torque in a 7" motor, the largest that will fit, to make a significant difference with the motor as part of the diriveshaft.

	The EMIS has a plug to read from the OBD port. I repositioned the port so one does not see the plug when sitting in the truck.
	The EMIS is hidden under the dash above the brake pedal. While it looks like a bit of a mass of wires they are hidden away. You can see the wire wrap that goes from under the dash through the firewall to the motor and controller. It carries the 12V power for the solenoids the serial connector to communicate to the controller and the temperature sensor wires.
	Another shot of the EMIS unit installed. The bare connector goes to ground. The other side of the EMIS connects to the programming unit and has a serial connection to the controller. Fortunately I am able to hide the unit and the wires up under the dash so they are not visible. The EMIS has a list price of $650 and it does it's job well.
	This is the TIM, (Technician Interface Module) that you use to set the parameters of the EMIS. It also allows monitoring of voltage, motor amps, temperature and other variables. I am told there will be an inexpensive display only option in the future. While the TIM is needed to set up the system it is not needed to run the EMIS system.
