IMO/IME >12.4 in WOT is too lean.

 

Are you talking about the corrected a/f?..coz if most people are saying the stock sensor is more accurate then i guess i'm running a bit rich. In the 10's-11's..i should see around 11.5-11.9 ratio wot. I guess i gotta get a wideband sensor to be sure....

 

I am talking about a using a wideband, i would not consider anything else as accurate.

My CTSC+AC @7psi runs at 12.5 low down until vtec at 4krpm then ~12.2 in vtec tapered down to 12.0 at redline

 

Hey,

Here is that datalog.



At the point the cursor is at my wideband was reading 12.2:1
So it gives you some idea of the difference between the readings.
