ok well me and my bud just sucessfully installed his Apexi turbo timer with the good help of the tutorials on here and stuff. we didnt hook up the A/F wire yet. but we are this week cause we where on a tight schedule... the wiring harness took forever to get to get in in that tight space. ok so when we do it this week.. i know they arnt soo perfectly accurate. but what kind of reading for the o2 and the A/F should we be getting. like with anyone with the Apexi ( pencil looking one ) that has it and is running the a/f and o2 what are u getting... thanks.

anyone? or like what kind of readings should we get.

 

Because it's narrowband it's only accurate around stoich i.e. 14.7. Totally inaccurate when under WOT or for tuning purposes.

 

I just installed mine, the A/F is reading between 15-17, and it seems to fluctuate properly up and down according to the vehicles performance . After installing mine my keyless entry stopped working ... did you have any problem with that?
