I can't say that I really understand how this can be. I've never had to use the low impedance driver but it's my understanding they are built SPECIFICALLY to interpret min/max pulse voltages and convert commanded duration and slope to one that is compatible with the injector. If it doesn't do that well, then it shouldn't exist. lol My only other thoughts on that are that it should be user programmable if there is a standard of some sort (written or unwritten) that is loosely followed when manufacturing these injectors. Am I missing something or does that about sum it up?
