if its installed with the arrow on the maf pointing toward the engine and youve set the dip swithes for your configuration and MAF and set the knobs accordingly per directions , then it should work
check your scanmaster for AF (air flow) of 5-7 at idle and drive it , then check your BLMs if they show good and not drastically off then its probably working
if you dont have a scanmaster you should consider purchasing one as it helps you set the tps and IAC and keepa an eye on lots of other things
a scanner tool will also show the info you need but the scanmaster can be hooked up all the time and will show you all that the scanner can and display retard degrees and 02s all the time if you plan to put your foot down, it will let you know if you have knock and you want to avoid knock,
another good tool to have in addition to the scanmaster is directscan and a laptop , then you can record the data and review it or have someoone here look it over for you
