Searched, seemed like it pulled every thread with the "speed density" keywords. So pages, and pages of irrelevant info.
To have a simplified engine bay, looking to do a speed density tune on a bone stock L31 so i can do away with the MAF, and ducting.
Currently 1998 Tahoe PCM, can that black box even do an SD strategy?
I could swap an '0411 PCM if someone had that file, but since it's bone stock i saw no need to uprade the PCM.
And the mail order tuners all say "we don't do SD tunes", and i understand that SD tunes need a dyno, or road tune data logged.
But was hoping someone had a starting point i could dump in.
BTW, never tuned EFI before in my life.
Thanks.
