Bit of a project... made an MAF/AFM converter. The MAF is a common VW/Audi one and the little red PCB maps the signal to mimic the original AFM. The engine runs, but not driven yet, want to get an air filter on there first!
Plugs straight into the AFM socket and then just needs a 12V feed to run the MAF. Is there a good place to get 12V from here? I've got a wire all the way over to the blue post in the scuttle.
Why? Just because! Not sure if the 'less restrictive' and 'more responsive' are actually true... but certainly the old AFM is a mechanical device that wears, hard to repair and expensive to replace.
