Ej222 and its stock ecu, from what I was reading this was one of the only cars that had speed density this model year (99 Brighton ).

And I know that with a MAF on certain cars, the thing wont run barely unless the MAF is all good.

Like I said, I just have a loose understanding of the 2 systems and how it manipulates the air to fuel and then like you said, seems it would barely have anything to do with that.

Just from your experience, what are some protocols moreso that I can take to make sure a map/sd system is working optimal.
