What's also improved/better compared to the original unit:
- The unit is protected against overvoltage (defect voltage regulator/rectifier, bad battery, ...).
- The unit is protected against a defect ignition coil and reverse battery connection.
- The unit has a acceleration correction, when the bike rev's up the ignition delay will be a bit more (in proportion). Smoother acceleration.
- The unit uses digital technique, so it is more accurate and temperature changes have no influence, the curve is also optimized for more power.
- When the battery voltage changes the unit will change the control to the ignition coil so the spark power will stay the same.
- Start mode, during engine start the unit will give more current to the ignition coil for a faster start.
