If I install the 2 Bar upgrade OS do I need a MAF that outputs the signal relative to 2 Bar also, or does the PID just rescale the existing output from the MAF?

2 Bar is speed density only meaning no maf.
It doesn't have to be perfect, it just needs to be done in two weeks...

So if I use 2 bar SD, does that mean the air flows are calculated and the MAF measurement is ignored?

there should be no maf measurement since it will not be there.

Now I'm confused. You mean that I should physically remove the MAF?

No you don't have to remove the MAF.

If that is the case, does it do anything at all?Originally Posted by EC_Tune

Once you fail the maf I don't believe it gives a reading at all.

You will still get MAF Hz and MAF Airflow but the PCM ignores it if the MAF is failed (DTC P0103 shows up with the scanner).

As the title says, to use the 2 bar SD will I need to replace my esisting MAP with a 2 bar unit?

yes.

Where do I buy one? Any recommendations?

This time you said MAP. You meant MAF right?
NO, I meant MAP. I think I got my question answered about the MAF not functioning under speed density (SD) but in reading the info about the 2 bar SD operating system it calls for a 2 bar MAP. The stock on is only a 1 bar MAP, so I have ordered one from on-line.

Does anybody have the part # for the 3 bar map to replace my stock one?
I have the number for the 2bar map sensor, and its Chevy part number 12580698. It is used on the supercharged Cobalt, and is a direct fit replacement for the one bar unit on the LS-2. It is what I am using on my 2006 Corvette turbo coupe. I know its not 3bar, but I hope that helps.
