I've got dyno time booked already for mid next month. All I need to know is a ballpark figure so I can tell if I'm running stupidly into the black. If you don't know, no worries. Feel free to donate a wideband to me mate ;)

Lol, settle pettel :) I had a blocked fuel return which was causing 90psi base pressure and richer than or equal to 10:1 afrs. I found the return blockage and fixed it, and my pressure returned to the normal range. My R still runs rich though, so I need to get to the bottom of it. I didn't block my ...

Cool, yes, a wideband would be great, but I'd like to know where the stoich point is. Also, it'd be nice to know if I am still running at 10:1, or if my fuel restriction mod did the trick. No tuning, just a rough guide. I'm sitting at 1.4v at the moment under WOT and also at idle. Can anyone give me...

O2 Sensor Voltage SR20DET

Hi all,

Does anyone happen to have a conversion table, or at least know the voltage to AFR equivalents for the 1.5V O2 sensor in the SR20DET? Specifically, the GTi-R. The voltages appear to be completely different to usual zirconia sensors.

Cheers.
