Just wondering, if fitting ITB's where does the ECU get its air flow info from? Or does it even use a AFM sensor?

Apologies for a daft question. :embarrest:

An air flow meter (AFM) is basically a MAF (mass air flow meter) so fitting ITBs wouldn't effect it. I'd imagine the ECU would automatically adjust the fueling although a remap would be a better solution.

You wouldn't really need a remap if fitting BBTBs (big bore throttle bodies) so the same would apply.

Ah, so individual throttle body manifolds will still have a MAF sensor then? :)
