racerx260 Posted January 24, 2006 Share Posted January 24, 2006 I Currently Am Running Stock 83 Turbo Motor And Ecu At 10 Lbs Of Boost.is There Any Advantage To Useing Stock Injectors From A 300z.i Already Have The Injectors And Was Hopeing To Prevent Running Lean On Top Without It Being Too Rich At Low And Mid Rpm. Will The Stock Ecu Control That?will The O2 Sensor Control The Larger Injector From Running Rich And Take Advantage Of More Fuel Flow At 6000-6500pm?

zguy36 Posted January 24, 2006 Share Posted January 24, 2006 The stock ecu will not automatically correct for larger injectors. The O2 sensor circuit has a max of 5-10% correction, and does not correct at higher rpm or engine loads. If you want to run larger injectors with the stock ECU, you will have to tighten the spring in your air flow meter. In my opinion, get a megasquirt. You can't beat the bang for the buck, and at $250 for the MSII, there isn't much money going out the door. -jeremy- Quote Link to comment Share on other sites More sharing options...
GrayZee Posted January 24, 2006 Share Posted January 24, 2006 300zx injectors are smaller (unless it's a turbo) in which case they are the same size as a L28et Quote Link to comment Share on other sites More sharing options...
zguy36 Posted January 25, 2006 Share Posted January 25, 2006 What would be the point of swapping injectors to the same size injectors? Quote Link to comment Share on other sites More sharing options...
Brad-ManQ45 Posted January 27, 2006 Share Posted January 27, 2006 zguy36 is right, both the 280 and 300 ZXT's used the same size injectors. Quote Link to comment Share on other sites More sharing options...
