Hello !

At first : My english is not "so good" , i'm sorry for that !

I've seen in the manual a picture how to wire 8 injectors. Below that is a picture called "And to pair injectors in parallel" !

Please look here : http://www.vems.hu/wiki/index.php?page=MembersPage%2FPhatBob%2FUserGuide

May be it works when you wire two injektors on one exit of the ECU, but i think they must have high impedance ...

I cant promise you but its the way i see  ;)

Best regards Martin from germany

In VemsTune, press F1 in the "injector staging" dialog.

With 5 primary injectors, you have 2 secondary injectors directly following the first 5 in the injector output table.

So you'd need to put up to two larger injectors further out in the inlet then?

Yes, or put it another way: You have two outputs to drive however many injectors you need further upstream from the head.

Example :With 5 extra staged injectors wired 3 and 2 in parallell on the two staged outputs.
