Phasing
The default injector phasing for the primary injectors is determined from the Firing Order
information from the Ignition Wizard. There is a fixed offset of 540 for injectors. After this offset is
added, the system checks to see if the result is less than 720. If the result of the calculation is
greater than or equal to 720, it is subtracted by 720 from that result
Example:
4 cylinder 1-3-4-2 firing order:
Injector 1 phasing = 0 + 540 (offset) = 540
Injector 3 phasing = 180 + 540 (offset) = 0
Injector 4 phasing = 360 + 540 (offset) = 180
Injector 2 phasing = 540 + 540 (offset) = 360
O2 Feedback
Lambda sensor assignment is determined by assigning a value of 1 or 2 to the InjXLambdaFB
channels. A value of 1 will assign the Lambda 1 sensor and a value of 2 will assign the Lambda 2
sensor. Min value = 1, Max value = 2
