Is there anyone in NZ that rebuilds Bosch AFMs? I have read the stuff online re bending the arms to track across the PCB over fresh material, but would prefer to use someone who does this kind of work regularly and can make sure it meets factory tolerances, settings etc. e.g. something like what this guy in US does: http://www.bavrest.com/air-flow-meters.html As a side question/alternative is anyone here running the latest Miller MAF for the M20 on the standard chip that comes with it? I want to keep my car pretty much stock, but a MAF tickled my interest as a logical reliability and mild performance/economy upgrade, but with no other mods on the car I don't want to shell out for a custom chip. My concern about getting a standard chip is I'm guessing it would be tuned for US octanes.
