Speed density to Mass air

[10strokin]

Does anyone on here know what year the Ford 2.9 engine went from Speed density to Mass Air, and was it a california only thing or nationwide? Any help appreciated. thanks!

The change happened in 1991 and it was largely a California thing. There are very few MAF 2.9 parts to be had outside of Cali and the surrounding area.

I don't know if he sold it, but user SteveAlvey had a conversion kit for sale on here a few weeks ago.

The required computer originates from a 1990 California 2.9L with a MAF set-up. This is available (rebuilt/reconditioned) from Ford (about $240 + core charge) or after-market (Pepboys or Checker Auto, $100 + core). Finding it: I called Checker Auto main warehouse out here in Arizona and found they actually had the computer in stock. It's a remanufactured unit by "Cardone". EEC-IV Computer = Checker P/N 78-4905 (manual trans version). The original Ford EEC-IV P/N is F07F 12A650-DA (manual trans version). I think the auto trans version of the computer is a -FA.

I have verified that P/N F07F 12A650-FA is the auto transmission version.
