A lot of you are WAY off on this subject!!!!!!!!!!
The injectors are matched to the ECU. You have circle, square or triangle injectors and that is determined by the OHM reading of the injectors!!!!!!
THE INJECTORS HAVE THE SAME MARK AS THE ECU, THE FUEL RAIL IS ALSO MARKED ON THE F-7 IF YOU LOOK!!
You can not interchange ECU's or you will run rich or lean, depending on the injector marking.
The outcome of the matched setup, is that all machines RUN the same!!!
The reason behind this is when you buy a lot of 20,000 injectors, they do not ohm out and flow the same, and you don't throw out the one's that are out of spec. you use them with a richened or leaned fuel curve in the
