Hey sorry i'm a newb, but i just bought an 02 wrx and it came with an apexi auto timer (turbo timer). I was just wondering how to acurately read the information that it gives. When i'm on the A/F/ O2 mode it gives number between .2 and .95 and i was wondering what they meant. When its on the A/F it gives numbers like 14.6 or something. So if anyone could help me with the interpretation, like what are normal readings and what do they mean, that would help. Sorry if this is the wrong forum to post this in. Thanks.
