My recent conversion of my EA81 to SPFI has gone well. The only symptoms now that are an issue is about 60% power...down 40%. Runs smooth etc.
Took it to a guy that specialise sin injector systems. Bare in mind we never had the SPFI system her ein Oz, in any Subaru.
He checked the conversion and found all items like fuel pump location, pressure and timing to be ok. He diagnosed (95% certain) a faulty MAF. The MAF was very slow to react and isnt operating correctly according to his experience.
Have purchased a secondhand one form your neck of the woods. Can anyone tell me how to test it? what are the operating details of a correctly operating unit? I've been told that people that test these usually tst a new one and have those details on them whenever a unit comes in for inspection- allowing them a benchmark to go by. But in Oz, this isnt possible as there are none around.
Any help appreciated.
