T4 with 8 injector wiring???

[Zim]

Hello,Im Robert I have a question.
How i have to wire ,when i have 8 injector on an T4 Ecu .
Thanks for Help....and sorry for my Bad English!

Wiring diagram does not say much.

8 injectors in what setup ? Engine ? 4 cylinder ? 8 cylinder ? staged injection ?

Hello, Sorry for the low Information from my side.

Yes 4 cylinder, 1440ccm Hayabusa Engine , ITBS , two Injectors in every cylinder 1. in Bridge second before the Intake( Funnel),Non Sequetial.
I want to use: Twin Injectors fitted ;Second Injector Blend Map -> in Sofware configuration
I dont find anything in the Wiring diagramm....

Do I have to take: first Stage Cylinder 1;4 to Injector 1 Output
first Stage Cylinder 2;3 to Injector 2 Output

second Stage Cylinder 1;4 to Injector 3 Output
second Stage Cylinder 2;3 to Injector 4 Output

This is my Thinking ,but I really dont now ,is this Thinking right!

This is correct

You've only got 4 Injector drivers to play with and they are all used in sequence to run a 4 cylinder and are paired to run grouped on an 6 or 8 cyl - so I don't believe you can do what you want as drivers can't be switched on or off with this unit. I use 8 injectors on my 4 cyl turbo suzuki but the ecu has 8 injector drivers, runs fully sequential and allows blending of primary with secondaries for boost increase.
You may be able to parallel the injectors per cylinder to act as a 'big' injector but no separate / individual control - is my understanding!

S60/T4 can run 8 injectors, but not sequentially, only semi-sequentially

Okay great,I will try this! Thank you all for the feedback! great and fast Community here !

Yes - but can 4 of those eight run different injector volumes / mapped numbers to the 'primary' ones? That is what I didn't think either could do and what I was trying to say. If i'm wrong, i'll delete my post as incorrect info is worst than no info!

Yes, different injector sizes are supported.
Outputs 1 and 2 are for the primary injectors. These need to be the same size as each other.
Outputs 3 and 4 are for the secondary injectors. These need to be the same size as each other, but can be different to the primary injectors.
