CIS-TURBO

CIS-Turbo (Bosch K-Jetronic w/Lambda) Engine Control System:

The CIS-TURBO engine control system is a mechanical, continuous injection system which is electronically controlled. The system is based on the Bosch K-Jetronic fuel injection system. Like the CIS-MOTRONIC system, a single electronic control unit (ECU) is used to control the fuel delivery and ignition systems. The ECU monitors information from various engine sensors and uses this information, compared with information stored in its memory, to precisely control the fuel and ignition systems for lower exhaust emissions, better fuel economy and better engine performance, under all operating conditions.
