[Diy_efi] sequential injection timing

I consider a 3% gain in power something to get excited about. Running
100octane race gas I have found 2-3% gains in some small motorcycle
engines. Alchol fuels are more sensitice to EOI. However, I agree that how
much power will vary with EOI, is very much largely engine and injector
dependant.

You mean injection timing in back to back tests? I didn't completely get
you on that one. Where are you located, if I may ask?

Point taken on having references. However will you agree that SMD suffers
on closing and opening of the injector? And that SMD is a function of
pressure?
