NEW FEATURES AND IMPROVEMENT
Improvement of sequential gearbox management:
• Optimization of the gear upshift time (faster upshifting).
• Ignition cutoff at gear downshift (faster downshifting on strong breakings of the vehicle).
• Possibility to select the old way of shifting on slower or less precise gearboxes.
• The ECU agrees to intervene on the engine even if the gear position measurement is in error.
Read carefully new documentation for sequential gearboxes.
Significant improvement of the engine startup security (From V210)
• In the previous versions, during difficult conditions of engine start-up, the microprocessor could

the capacity to perform its measurements (throttle, pressures, temperatures, ...), causing an engine stalling.
• This version prevents the loss of the measurements even in case of battery tension drop down at the engine start.
Improvement of quality and robustness of the injection command (From V200):
• When engine speed instabilities of a sufficient level (due to vibrations or else) happened, versions previous to version 200 may

one or more injections, up to making thinking to a small limiter.
• The new versions never

any injection (nor ignition) whichever is the engine operation.
