12 injector

[chris parnham]

Hi , what’s the best way to wire up 12 injectors into a 2jz 

it’s on the plug and play Ecu 

can I have 6 sequential then the second rail on batch ? 
 

regards

are they 12 identical injectors? 

do you want to run them staged or can they all be running at the same time?

They are similar size (650cc) but are different, Id like them staged as a preference

Provided your ECU has inj drive 7 & 8 available then set injection mode to Sequential/Multipoint group.  The primaries (Inj 1-6) will fire in sequential and the secondaries (in 7 & 8) will be fired alternatively in 2 groups.  Typically I suggest wiring odd numbered cylinders to Inj 7 and even cylinders to Inj 8 to spread pulsations along the fuel rail nicely.
