        i believe he's waiting for Monsoon to chime in here....

        to get the car running, you can use the B3 (factory) ecu. for better performance, the B6 ecu should be swapped in. dont' worry about a B6t ecu, as they're harder to find, and don't have the same plug-ins.

            But I think this answer covers it pretty good. Sarcastic though it may be.

                There are 2 & 3 plug versions of both ecu's, you probably want the 2 plug

                    Information that would have been yours had you made any effort to search the engine swap section.
                    Festyboy, since you'll be doing this swap for bobbyspider show him were the cap key is?

                        You need the b6 vaf if you are using the b6 injectors.

                          Greg, are you surmising that the B6 VAF shows a different value for the same volume/mass of air? doesn't make muche sense to me that mazda would change the values between .3L of displacement.
