Digital Motor Electronics MA 2.4<br />
The R <strong>1200</strong> <strong>CL</strong> is equipped with Digital<br />
Motor Electronics (Motronic) MA 2.4<br />
engine management system. In contrast<br />
to the Motronic MA 2.4 for the R 1150<br />
models, an electronically regulated cold<br />
start control with idle speed control is<br />
used for the R <strong>1200</strong> <strong>CL</strong>. as on the R <strong>1200</strong><br />
C Classic.<br />
The MA 2.4 control module monitors engine<br />
operating parameters via input signals from<br />
sensors and switches.<br />
10<br />
These input values are evaluated by the<br />
control module and used for calculating the<br />
injection on time and frequency, optimum<br />
ignition timing angle and idle speed control<br />
based on programmed operating data<br />
maps.<br />
This system provides a consistent idle<br />
speed of 900 RPM at normal operating<br />
temperature as well as automatic increased<br />
speeds for cold engine startup which gradually<br />
changes as the engine warms up.<br />
