Introduction
Purpose
SMT8-L Features and Wiring
The SMT8-L has a 384 site ANALOG map, which is added to three 24 row side maps of air temperature, engine temperature map and manifold pressure. The analog map sites are selected by the throttle position (or any other load signal) and the RPM.
The wiring of the SMT8-L for the NARROW BAND LAMBDA INPUT is shown in the diagram below.
The wiring of the SMT8-L for the WIDE BAND LAMBDA is shown in the diagram below.

Conclusion
Most of us spend 90% of the time while driving a car "cruising" due to speed and traffic restrictions. The SMT8-L is the ideal tool to improve the cruising performance, while enhancing the power output at full throttle when overtaking. This can be done by intercepting the "CLOSED LOOP LAMBDA".
