G.M. Multiport Fuel Injection Trainer by Megatech is a fully electronically controlled fuel injection system trainer constructed from a late model GM OBII type vehicle to teach fundamentals of fuel injection and engine control. The trainer can provide engine diagnosis and problems in the fuel system and has a complete operational fuel injection system with “built-in” fault simulation, sensors, actuators, and controls. All controls for the sensors are conviniently located on the front panel of the portabe cabinet.
