I have a question. as you know I installed some time a set of injectors from a williams, i have a 1.8 16v engine. the computer is stock, but I have one with a modified ecu. i failed to fall below 10% consumption of the urban way - by my calculations comes out a 10.5 - 11%, though outside I had a consumption of 7 - 7.5%, without having a sport running. today I read somewhere that the installation of larger injectors without an appropriate software not only make the engine go rich, without great results. is this the answer to my discontent?
PS : what is the right consumption to this engine ? but for a williams ?if this is the right one, it's fine by me. i only want the engine to run smooth and fine. thanks in advance.
