it depends on if you're using a socketed/chipped obd0 or obd1 ecu and what size the map on the ecu is scaled for.

thanks for the feed back. all i know is it a pm6 (OBDO) with the mugen chip with better fuel map and timming curve with no rev cut off. like i said it is for a DOHC zc-D16A8/A9 i had the D16A8 (rover) motor loved it slung the hole crank racing a 350Z hitting about 9500 to 10000 rpm and boom. i will tell you one thing i have it on the D15B and i hit 8000 to 8500 rpm all the time and it takes it like a champ. i am running the D16a6 injectors right now. so there will be no diff if i change them out?
