How accurate is the A/F reading Apexi Turbo Timer? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I cant seem to get it going, it always reads 10.0 so im guessing that its not wired up correctly, but I read the instructions and it says it doesnt work with Titanium type O2 sensor vehicles which included Skyline GTR and RPS13 Silvia/180sx ('91.1 ~ '93.1). Whats all that about? Any help, Thanks!

If its reading off the stock O2, dont expect much.

i have the same timer and it does the same thing, but what you can do is switch it to the voltage reading to see what the ecu sees from the o2 sensor. i still would not use it for tuning...

I've used it with good results but only use the o2 voltage settings and shot for mid .90volts when tunning for WOT (open loop).

its as accurate as any narrowband o2 gauge...

So im better off going with something like a PLX-M300?
