z32 maf safc 2 issues

i just came back from getting a conservative tune on my safc 2 with the sr maf. i was told the z32 maf code was 4 and 4 coming from 6 and 6 for the sr. i try it and only runs smooth on 4 and 6 so i guess my voltages are wrong? anyhow i upped the fuel a little bit across the board on high throttle and found some hesitation under hard acceleration around 3000rpm then its fine. i adjusted it a bit plus and minus and couldn't really get rid of it. so i switched back the the sr maf and everything is fine. i know when wiring up the n62 maf the orange wire goes to a ground so i put that on the radiator support behind the headlight. maybe thats my fault? do you guys have any explanation for this? thanks

there is a chart somewhere around here, that has the in and outs, based on motor and maf combinations. i think apex'i has it as well in their pdf installation file too. it' on their website
