Apexi AFC question

[knackaz]

i have sitting in glovebox an APEXI Air Flow Converter,, model number 9505-, looks kinda old schoolish

didnt realise it upon purchase of car-95 R33 gtst, engine cooked itself as a result of previous owner being a dirty scammer and ahd sumhow blocked holes in the radiaor with a chemi weld of some sort i suppose. ran some hardcore cleaner through the system and refilled. apparently it unblocked his quick fixes and dumped all coolant through holes in radiator. due to the fact that he had taken out thermostat(unknowingly to me) the car didnt register an overheat still as it didnt get hot in the first palce and then when it overheated it didnt have anty mcoolant in it to register on temp sensor.

anyway,sorry for the story. after a complete rebuild, i am curious as to what setting the afc is mmeant to be set on, i know the car number switch is correct, but unsure about the volume switch, it goes from like -6, -3, 0, 3, 6, etc.

is there a generic standard sort of setting it should run, or does it depend on other factors of the car eg-exhaust, injectors, air filters?

it is currently set on -3, but as i cant trust anything on this car after everything thats happend, i couldnt say if its meant to be there.

thanks , any help appreciated

can post pic if it helps

Set em all to 0, take it to a dyno, check the AFR's, and go from there...
