The MMS300 was only used for a few months (probably only mid-production year 1993 models but it's unclear), the MMS311 is much more common. The MMS300 has the same four connector plugs as the MMS200, the MMS311 has different i/o connections.

something I have been meaning to get for years now.
Was considering a chip, however, I have wrong ECU in the 95Q. The 93 FWD may have the right ECU tho as it came with a stock small bore maf (since been replaced with large bore)

Mance's MMS311 equipped B4 had a skinny MAF housing with the later electronics when he bought it. He is convinced that it came that way from the factory, based on the paint marks on the screws. I have not seen any other MMS311 cars equipped this way - every post MMS200 car I have ever seen has a fat MAF.
