Sub Injector, GReddy BOV

[S-14boy]

I tried searching the forum for this but came up empty handed. Can some one please tell me what in the F a sub injector is. I got the GReddy KA kit with FMIC and BOV, and the instructions for the BOV say if you have a Sub Injector make sure its between the BOV and Throttle Body.

do they mean like an additional fuel injector?..yeah i bet thats what they mean. it makes sense.wouldnt want your bov shooting fuel into the engine bay

[S-14boy]

Could it mean something like N2O????

No, slo had it right, extra injector. The bov would (could) blow fuel into the engine bay if you positioned the injector before the valve.

how dose sub injector help out? and how is it done?

[SSS]

a 'sub' injector is another name for an extra or auxillary injector. It just provides the extra fuelling the engine requires without changing out the stock injectors.

so how would u wire it up, u dont have to have this this is just like an extra way for fuel to enter the engine right? what is u have 370cc or 550cc inkjector i would not need this would I?

no, its not neccessary if you have your fuel situation already figured out to give enough fuel for your power level. Running additional injectors requires an additional computer. Whether it be a nice piggyback, standalone, or AIC (additional injector controller)
