Hello, I need your suggestion because I do not understand how to identify the different types of bosch ecus, for example, edc15 or edc16 because, unfortunately, are not the same as the marelli, which is written above 6f3 or another. For example, the other day I had to do a quick diagnosis for a stilo 1.9 120cv and them for them when they are entered in multiecuscan I had to choose between edc15 or edc16 and I entered in panic, I didn't know which one to choose!! But then, luckily, I remembered that that car was on a edc16.. little stuff I would have lost 2mins to do the test if the diagnosis I came with edc15 or edc16, but as well for personal culture, is there a way to distinguish them? for example, the initials of the codes or things like that? Or you must think with the year of the car and the hp of the original?
