This function allows injector wiring to be tested and can also be used to help with injector flow testing. This function will only operate when Engine Speed is 0 RPM.

 

Injector Test Settings

Injector Test has the following options available:

·OFF - No injector drives will be tested.

·Inj X (2ms 10Hz) - Where X is the injector channel. When selected injector drive X will pulse 10 times a second with a pulse-width of 2ms. This will continue until OFF is selected from the Injector Test menu.

·Adv Test Inj 1 - An advanced test mode only for injector drive 1. When selected the advanced injector test will start, and once the test is finished Injector Test will return to OFF.

 

Test Injection Counts - The number of times injector drive 1 will pulse for in total. Only used when Injector Test is set to Adv Test Inj 1.

Test Injection Frequency - How many times per second injector drive 1 will pulse. Only used when Injector Test is set to Adv Test Inj 1.

Test Injection PW - How long each pulse will turn on for. Only used when Injector Test is set to Adv Test Inj 1.

 

Note: The fuel pump (if controlled by the ECU) will be disabled during this test procedure as RPM is 0. If testing injector fuel flow using Adv Test Inj 1 the fuel pump will need to be on. Select the Auxiliary Output channel the fuel pump is allocated to and change its function to Test (On), this will cause the fuel pump to turn on. Remember to set the Auxiliary Output channel back to Fuel Pump when injector testing is finished.

 

Example:

Injector Test: Adv Test Inj 1

Test Injection Counts: 30

Test Injection Frequency: 5 Hz

Test Injection PW: 5.0000 ms

 

When setup like above the Injector Test function will pulse injector drive 1 five times per seconds (every 200ms), for a pulse-width of 5.0000ms. In total there will be 30 pulses, and the entire test cycle will take 6.0 seconds. At the end of the test cycle injector drive 1 will stay off and Injector Test will change to OFF.
