S/C owners: collecting information - Toyota Yaris Forums

Got some new info on AFR, I'll repeat the rest of the stuff as well. Looks like my experiences pretty much parallel camelll's.

Air Fuel Ratio:
* 11-12 range at wot in open loop (making up to 8 psi)
* mid 14s-low 15s in closed loop (both on and off boost)
* steady at 16 during DFCO (open loop)

Fuel Controller Wiring: Splice clips (the good kind, not the shit ones from the kit

)
Spark Plug: NGK 7 heat range plugs
Pump Gas Quality: BP 93 octane plus lucas oil octane booster

I just got the wideband a/f gauge in over the weekend so I'll continue to keep an eye on it. Similar to what camelll said, I see a brief delay in going to open loop at wot, but I see the same delay when entering dfco, so it may simply be may be the scangauge catching up. My main desire would be to eliminate long-term use of the fuel additive to prevent knocking.
