i just put in the apexi turbo timer and there is a setting where you can set the a/f and o2, where am i suppose to get it at i think it goes by incriments of 10, cause the way it is now its always showing that im leaning out even at idle, it goes red when i barely step on the gas, its for gsr block, with b16a head, any help would be welcomed, thanks

 

I have one too and it's a narrow band a/f ...junk.. all I need it for is the small size and read volts and turns my car off in ??? mintues...

Get yourself a wideband a/f gauge....

 

I noticed that those timers say that it dedecuts how hard you have been driving and times the timer according to yoru driving. Is that bs or does it actually estimate it nicely?

 

did you wire up the correct wire to the 02 signal? check that. it should read just fine.

 

i know for sure i wired up the o2 correctly, but just tryin to figure out how to set the a/f
