V44 wire in ecu in a 6 cylinder

[MMC_Tuner]

Hi, I’ve got a Vipec V44 in a car that I’m repairing and the engine is a 6 cylinder V6 6G72. 
Since the V44 can only support 4 injector outputs, I am short 2 outputs. 
I believe I will have to wire them up in pairs and run them in pairs. 
 

The firing order for the 6G72 engine is 1-2-3-4-5-6. 
 

I’m assuming I wire them up in pairs of:

1&2, 3&4 and 5&6.

 

settings should be multipoint group injection.

Please let me know if I’m on the correct path to this setup.  Thank you

In multipoint group mode the injector drives are fired in 2 groups, all even drives fire together and all odd drives fire together.  

Whats the injector resistance?  If low impedance, does it have a ballast resistor?

The ballast has been bypassed.  They are high imp injectors. 

 

I've wired injectors

Output / cylinder

1 / 1 and 2

2 / 3 and 4

3 / 5 and 6

Its not going to make a lot of difference either way, but the way you have it is a decent option.  You will have cyl 1,2,5&6 all squirt at the same time, then 3&4 will squirt together either 180 or 360 deg later depending on injection rate setting.  

So on the first squirt you have 2 injectors on each side firing together, on the 2nd squirt you have 1 injector on each side firing.   The main thing I like to avoid is having all injectors on the same side squirting together as this can cause large fuel pressure oscillation - so your set up is good from that point of view.  Use an injection rate of 1/2 cycle provided your injectors arent bigger than say about 600cc.
