Virtual tach learning
To program Virtual Tach:
After the install is complete, remote start the car.
1.
If the car does not start on the first attempt, let the remote start at-
2.
tempt again.
Once the car starts, let it run until the parking lights come on.
3.
When the parking lights come on, shut off the remote start with the
4.
remote - that’s it! Virtual Tach is programmed.
Note:
Virtual tach is not recommended for use on diesel trucks.
Virtual Tach handles disengaging the starter motor during remote start-
ing – it does not address over-rev. If the customer wants to have the
over-rev protection capability the tach wire must be connected. This
may involve more installation shop charges than initially quoted.
Important:
If the Virtual Tach mode over cranks or doesn’t crank the
vehicle long enough to start and run the car, use the Bitwriter to add or
subtract the starter output time. You can adjust the output time in incre-
ments of 50mSec of the learned time using the Bitwriter.
