Injector testing
When you want test injectors you must know that HRR2 have 2 test types ( Continued and Timed ).
In both test is possible test up to 4 injector at same time, the test are done in sequential mode at 4000RPM.
Sequential means that only open one injector at same time, this allow keep the pressure into the ramp stable.
To test more than one injector simply connect is and done. ( max 4 injectors).
If you only want test one injector after of plugin it you must press the middle button one single time.
Continous test
Plug the injectors, and every time that you push the left button will change the injector openning time in the following sequence:
If you have connected at least ONE low impedance injector only will work a 2mS Openning.
The injectors will remain working permanently or until with left button you reach the STOP position, or press Right button, or press center button or disconnect the HRR2.
This test is usually used for cleaning of injectors.
Timed Testing
Plug the injectors, when press the right button will start a 4mS test for 1 minute.
If you have connected at least ONE low impedance injector only will work a 2mS Openning.
This allow control that the all injectors have the same flow level.
