AFC reads 5.3+v from MAF - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

installed a mystery turbo and now airflow % is off the charts. When it hits 100% know signal skyrockets. I know the knock signal is kinda wack on the s-afc 2 but it cant be good. So I installed 50lbs topfeeds and bought a z32 maf and tomei adapter harness. Only problem is instructions are in jap. I did a search on here and fresh alloy. Can anyone translate?
thanks

emailed phase2 and they said it should matchup wire for wire (color). ill post tonight how that works out.

it is straight forward wire for wire install. new maf is no where close to maxing out.

what is a safe knock level reading on an s-afc under boost?

i have bigger than stock turbo, 50lbs inject, greddy frontmount, s-afc 2, wideband, and other bolt-ons at 18ish lbs.
knock calibration is set at 30something/ 40something
under full boost knock reads in the lower 200s.
what do you hit?
