Secondary Injectors

[Gtrgodzilla67]

If i wanted to run secondary injectors in my rb26 what would i need in relation to ecu ? as do i need a seperate unit to operrate the injectors or do i take the pulse wire from the ecu and loop it into the second injector ? or will this overload the circuts on the power fc

just curious

cheers pete

All the set ups i've seen Pete have used an injector equalizer to control the secondary injectors. I just pulled the set up out of my R32 GTS-t along with the extra 2 injectors.

From memory you can change the injector settings on PFC but only for even numbers 4,6 cylinder (someone can clarify that though) but the way i see it as the secondary injector is not being used 100% of the time you wouldn't be able to control it from the PFC without modification.

In all honesty though you shouldn't really need anymore than 6 if you have upgraded from stock and the tune is sufficient, i found that it was just over fueling hence taking them out
