different voltage in and out settings...

im asuming youve got some type of piggy back or something, if so you can change the settings in the piggy back or standalone. however, if youve got a chipped ecu youre going to need to stick with the mafs that it is chipped for, or have it rechipped somewhere...

aka stick with the z32 mafs.

once you start pushing major power you need to switch to a map sensor and standalone on an sr anyways.
