AEM 30-4100 UEGO Wideband A/f Gauge

Why not purchase the Uprev cable and use the Cipher software to read the stock widebands? The cable/software runs about $200 and you can datalog a lot of info other than AFR.

As for AFR at WOT, I've seen anywhere from 12.5:0-13:0 used on the VHR. Mine is tuned for 13.2:0 at WOT, with pretty much stock ignition timing (i have an HR G sedan)

The stock widebands do not provide a consistently accurate number. The shape of the AF curve is generally correct, but the absolute number is not correct especially as you get richer and richer such as with forced induction.

Thanks for the reply on this A/F Target. Since I posted the question I found that most tune between 12.5 and 13.5, so I would just go for 13.0 and lean out while watching the EGTs. But for non-racers, I'm sure 13.0 is fine.

Do you know what the WOT Ignition Time hits for # of degrees BTDC?
