I'm not sure yet, but inclined to believe that kind of test would work. NZNick. '99 10AE, Stock An injectors dead time varies but RC 1000cc injectors will have a DT typically between 420 and 495 µsec, you'll just have to play with it a bit while its idling to find the sweet spot. Thread starter dmscrx; Start date 3 March 2015; D. The data in this table is represented in milliseconds. Only took 20min or so to run through all the voltages 3 times and we've got It turns out that i might set incorrect data as Dead time for my previous injectors - 1zz and for the 2zz i don't have any reliable data. I am really tempted to try what is the dead time voltaje latency of rc 550 pl-8 injectors to use with ecuflash i read the dead time is 180ms but i need the different volaje latency of the injector to mod with ecuflash. Fuel Injectors: RC Engineering 370cc, 550cc, 750cc, 1000cc. Fuel injector cleaning can bring your injectors back to original factory specs. Shop by Categories. Save Share Reply Quote Like.
