As usual the component quality is outstanding, and the latest version has additional features and functionality to make it even better.

In addition to independent ignition control for up to 8-cylinders, rev limit control by the ignition cut-off is possible (only for race use). With this function, the boost can be maintained to the full level even while stopped before a drag racing launch.

An air fuel meter can be connected directly for use with closed loop mapping and data logging functions. User-friendliness has been taken into account.

High level fuel & ignition controls based on full signal input functions and other controls that are connected with auxiliary outputs by option output function are available.
