I didnt say that they dont match deadtimes. The amount of data points is smaller now, ie from 10 to 3.
Simplified spoon feeding comming up.....
Basically if you match an injector at full flow, and then match and injector at 2 more points, say 3ms and 7ms. They will be matched by deadtime. There really only is 2 variables in how much fuel an injector will flow when pulsed , how much they flow and how long it takes for them to open and close, ie latency/dead time/ blah blah. If the injectors all flow the same at full flow, that means the injectors flow the same so your down to the other variable, latency. There is some other stuff(like high and low slope on the new ford ecus, etc etc) but for old honda ecus this is the basics of it.
