Forgot to mention - I searched on here and the internet, and it almost seems like those 2 numbers aren't the same, although I've seen people post .5 opening times, and some of the peak-n-hold injectors have lag times in the .5s.

I recently upgraded my injectors to 550cc (from 220cc), and I'm going to hone in on my 'correct' opening time.

They're Denso 195500-2020 saturated.

The lag time for them is .73ms .


Since I've got that spec, I was wondering if I can calculate the the 'opening time' that MS requires instead of ...

I ran only EDIS w/MS2 while I was sorting out my injectors.

I just left the MS2 injector harnass unplugged, and she ran fine.
The MS believes it's firing the injectors, but it doesn't know better.
Just make sure you cap off the unused wires when you're running ignition only.
