Driver for ECM Titanium

Spark Advance
The spark advance maps manage the ignition angle, i.e., with how many degrees in advance compared to the top dead center (TDC) the spark must strike.

Having full control of the ignition, thanks to those maps it is possible to have it postponed during the overrun phase to activate the pop & bang.

Maximum Speed
The speed limiter map has inside the value in Km / h to which the machine is limited. When this speed is reached, fuel cutting is involved to prevent the vehicle from exceeding it.

The map has several values, one of these is enabled during the vehicle configuration phase by the manufacturer, depending on the type of application (for example Vehicles for commercial use or AMG sports cars) by increasing the desired value, this limitation can be eliminated.

Lambda Sensor
With these maps it is possible to disable the monitoring of the catalyst Lambda sensor, to install a straight pipe or racing style exhaust.

Overrun Injection
Using the “Rpm threshold and Delay time for overrun cut off activation” maps and the Spark advance maps, it is possible to generate the overrun bursts commonly called “pops and bangs” Thanks to these maps it is possible to adjust the function according to customer preferences by varying the intervention of the “cut off” function and adjusting the ignition angle in overrun to make the sound more or less aggressive.
