Fuel Consumption - help

[WetGTR]

I'm running HKS 1000cc Injectors......too big?

I understand that larger injectors are not as efficienct, or should I say control over say smaller ones.

Still couldn't my AFR be improved for highway use say on light loads or maybe a closed loop operation or how about a whole new map that I can just zap in using a laptop. When I want it back to normal I can just re-zap it.

Am I just chasing my tail or should I just put up and shut up and be happy with everything.......who dosen't want to have everything! :headspin:

dude, you're only getting 70kms less than me and I only have 170 RWKW and you have 420AWKW. I'd be pretty happy

I'll swap any day!!!!!!

Larger injectors have trouble atomizing the fuel well with small duty cycles.

The larger injectors *nismo and I also thought hks* 'generally' have multiple sprays.

For example they may be a twin spray.

That was my understanding, I could be wrong.

for the injectors to atomise better wouldnt you need really high pressure in the fuel lines???

way above stock pressures???

420awkw is awesome to dude congrats!!!

I'm guessing that for fuel to atomise better, the finer the spray or should I say the finer the mist of spray, it will atomise better.

Fuel pressure would not have anything to do with this aspect, I think.

So in larger injectors they can have multiple sprays to makeup for the effiency.

I just checked mine and they are single spray units..... If I change them to something with multiple spray units, then do you thing I might get better effiency?

Thanks MsG_ChRiS... don't I sound the winger!
