Dim efi

I am very familiar with the existing OEM fuel pressure regulation - and it's shortcomings.

two events per revolution? Not really necessary, but ok if you want to. Trying to time events on a TBI takes a lot of processing. OEM's never bothered and still passed emissions just fine.

Later Ford MPI tunes off of the individual cylinder exhaust strokes and just moving the O2 sensor a foot will shake it up. The timing of the intake valve openings at various speeds with different runners will mean a big table...
