A little more from Tony


This is data from a batch of 100 of these injectors. This is flow deviation from injector to injector (every 10th injector was used for this test). The reason you see so much deviation down low is because of slightly different injector dead times from injector to injector. All our injectors are matched in sets based off of both flow and injector dead time. Make note, 2-3ms is where MOST of the life of the injector is, all idle and part throttle. Even with a good batch of current technology injectors, there can easily be a 5-10% difference in flow at low pulsewidths if the injectors are not matched in sets based on dead time. As you can imagine, 5-10% fuel flow difference from injector to injector at idle and part throttle can have a significant affect on how smooth an engine runs and also an affect on how lean you can run the engine



Here is the deviation data from a set of 4 that is properly matched based on dead time
