scotty nm35 Posted November 28, 2014 Share Posted November 28, 2014 Revs make no difference in flow tests, it just changes how quick the tube fills. The opening (lag) times are critical for idle and obviously flow at 100% duty is important at the pressure you plan to run the fuel at. For the cost of cleaning and replacing the filter/Orings you should probably have looked at new EV14's.

Ruthr33 Posted November 28, 2014 Author Share Posted November 28, 2014 My car idles perfectly fine, I also only use 64% duty The question is. one cylinder 5.1 percent leaner = melted piston? Or.. 5 cylinders over compensating to get 14.7 afrs= loss of power. In a nut shell. Should I recon Buy new Or leav them be. It lives it's life on the limiter aswell Link to comment https://www.sau.com.au/forums/topic/451175-injector-variation-good-or-bad/#findComment-7433903 Share on other sites More sharing options...
MrStabby Posted November 28, 2014 Share Posted November 28, 2014 Have they been cleaned or just flow tested? Typically you would clean first then flow test. Some ECUs let you tweak individual injectors to compensate for variation. If you're running an rb26, put the highest flowing injector in #6 as the stock plenum tends to feed more air to that one. Nismo plenum fixes that issue. Link to comment https://www.sau.com.au/forums/topic/451175-injector-variation-good-or-bad/#findComment-7434058 Share on other sites More sharing options...
