 Fadec autostart ecu £210 (MPEG video).

Text Box: As you can see the latest Fadec autostart has to be the most compact full feature autostart ecu available, utilising the latest surface mount technology and double density pcb's. Hall effect or Infra Red rpm sensing can be used, the hall sensing version provides the most secure rpm signal and is unaffected by sunlight as some IR systems can be. Typically a standard 7.2v NiCad pack is used to provide power for fuel pump, e-starter and glow plug which connect to the ecu via standard buggy type male/female plugs.Battery pack voltages from 1.2v up to 15v can be used if required. Other connections on the main unit include rpm sensor, thermocouple for exhaust gas temperature sensing. As well as sockets for gas and fuel solenoid valves.

 

 

Fadec semi-autostart ecu £155

As with the full feature autostart ecu, the manual start is the same physical size but half the thickness as there are less connections to cater for. The same closed loop feed back system as in the autostart is used, this means that once the engine has reached idle rpm and control has been handed back to the throttle stick exactly the same software and programming is used to control the turbine performance.

All Fadec ecu's can be used with any engine because the extensive list of user programmable parameters which are listed below :

Autostart start menu adjustable parameters.

1. Temperature sensor calibration.

2. Minimum battery voltage during start phase, (Safety feature which comes into play should the battery voltage fall below the set value the start is aborted and 'lowBatt' message is displayed. This is only operative during the start phase, with a running engine the engine is kept running until the battery pack is empty.

3. Minimum safe rpm during the start phase.

4. Starter power during the ignition phase, (allows a 'soft' start for the e-starter).

5. RPM where starter is switched off during the start phase.

6. RPM where the starter is reconnected during the ignition phase.

7. Preheating time, (time from when ignition is detected to when the fuel ramp is launched to allow the combustion chamber to reach a temperature at which efficient combustion will take place).

8. Start gas switch off temperature.

9. Starter switch off rpm.

10. Starter power at the beginning of the fuel ramp.

11. RPM where the starter reaches 100%.

12. First rpm point in the fuel ramp, (the start fuel ramp is split into 3 user definable ramps.

13. Second rpm point in the start fuel ramp.

14.First start fuel ramp value.

15. Second start fuel ramp value.

16. Third start fuel ramp value.

17. RPM where the starter is reconnected during the start phase.
