eyeR Interceptor: Automated Engine Start How-to
With the eyeR it is possible to make it start your car automatically. All you do is insert key and turn it to the IGN position, then you simply tap the engine start button and the eyeR will crank and monitor your car status automatically.
There is a special security input that needs to be active in order for the eyeR to start your car. This has been added for more security/safety (Can be used as the neutral position or park position input)
Later I will add fully automated engine start, that will make the eyeR cycle through the IGN key sequence and automatically start your car. There is no need to re-wire you car again when this feature is ready as the diagram below will have all the correct signals and outputs already connected to the eyeR.
HOW Does It WORK!!
After momentarily pressing the "Engine Start" button (providing the security pin is enabled) the eyeR will attempt to crank the car while simultaneously monitoring the RPM input. This monitoring will tell the eyeR the exact moment when the car has started so the eyeR will know when to stop cranking. If the first engine start fails, the eyeR will try a couple more times.
To turn the car off you can do one of the following:
- Turn the key to the off posistion
- Momentarily pressing the "Engine Start" button again
- Pressing a designated button on the eyeR remote
- Sending the "Car Off" command to the eyeR via the PC
As you can see all that is needed is 3 relays to have full engine start control. Actually for just basic engine start only 1 relay is required, but i have added the 2 extra for fully automated engine start/turbo timer control.
If you having trouble understanding how the eyeR intercepts the signals have a look at the diagram below:
You will notice that normally your ACC line is a straight through connection, but cutting the wire and inserting the eyeR/relay combo will give you an intercepted connection. The signal will still function as normal but now it can be monitored and intercepted.
Ok, now that the wiring is done you will need to enable the feature in the configuration utility:
So, its not that difficult.. You simply enable the checkbox and specify the number of cylinders in your car. This will make the eyeR correctly calculate your RPM.
You can also trigger an output when the RPM is in a specific range, though this feature hasn't been added yet. Useful for a shift light trigger or an intercooler waterspray controller etc.
That's about it, as usual this feature will work with/without a PC.
