I have a Q's my turbo should be here any day and i jsut got my AEM wideband o2 sensor. and it says it reads "11.0 to 17.1 and i know it was stated before in threads but i was wondering where is it safe for the A/F to read out at , at ideal and WOT .. like the max A/F
thanks

Mid 11's @ WOT, 14's @ a steady cruise (Ideal), and it will prob. go of the scale (lean)under decel.

I'd say 12 to 12.5:1, on boost, WOT...

 

how come nobody posted when i asked the same thing?

what's the timing like under boost?

 

I agree. 12.5 to 1. But I would prefer 13 to keep the engine safe and last longer.

 

13:1 is more lean than 12.5:1. Probably not the best if you want you engine to last longer.

 

13's for a turbo engine? n/a's, sure.

 

Yeah how much ignition retard are you guys running?

I can see 11.5 to 12.
