[Diy_efi] Measuring Pulse Width/Duty Cycle of an Injector?

[Murray Gill]

Nothing personal Mike but would you be willing to explain how YOU would you
do it?

Could you also explain in simpler language what you were talking about in
your post with its most impressive language(see below).
Thanks,
MG
