How to test injection order.


I must come clean and tell you all that my injection order was wrong for about a year, since I installed the seq inj module, I got the installation information with a mistake and I have found it just recently.

Someone drooped me a comment about the seq inj order I posted on the seq inj post, he was right, my order was wrong.

Now I will tell you how to test it.

Normal injection order in 4 cylinder engine:

Cylinder 1 is the closest to the timing, cylinder 4 is the furthest.

First to fire: Cylinder 1
Second :      Cylinder 3
Third:          Cylinder 4
Forth:          Cylinder 2

1-3-4-2

In order to test your sequential injection order do the following:

Click on "CAN bus/Testmodes"
Click on "Output TestMode - Inj/Spk"

Here you can see you can test your fuel pump. coils and injectors, we will test the injectors.

Click on "Enable Test Mode" at the top of this window.

Injector Channel To Test: start with 1 and press start, that should make cylinder 1 injector work (you can hear and feel it)

Then:
Inj2, should fire cylinder 3
Inj3, should fire cylinder 4
Inj4, should fire cylinder 2

Click "Stop"
Click on "Disable Test Mode" at the top of this window.

Got it ?

GOOD !
