NEW VIDEO: Wideband/Boost readings. - Toyota Yaris Forums

Made a video of my gauges.

First clip is of WOT. Running lean in the 13-14 range with 17 IGN timing. Second clip is of conservative driving (no boost) 14.5-15.1 AFR, then going into neutral/coasting 15 AFR, then cruising w/ boost into a little acceleration section at the end.

My readings seem almost identical with noogie's video clip ( http://www.youtube.com/watch?v=05RZSyraA5Y ). However, I go into 15s instead of 16s when in DFCO. You can see that in my video, towards the end when I am coasting in the 700ish RPM range. HOWEVER, noogie's WOT numbers seems almost the same as mine, BUT he is in single digit IGN timing and I am not ( mine's is 17 IGN during WOT). I remember reading where largeorange front said Noogie should be safe since he's in single digit IGN numbers with the 13-14 numbers in WOT. I DON'T have single digit IGN numbers with my WOT numbers being 13-14.

Anyone care to shine light on this? Am I safe to drive even though I don't have single digit IGN numbers with 13s during WOT? I am running 14.5-15.1 during normal driving and even with boost. I believe those are safe numbers to be in and are stoich. However, I don't know if my IGN numbers during that conservative normal driving is ok or not. Because the A/F numbers seem to be good. Only when I am at WOT is when I am running lean (13-14) and I do NOT have single digit IGN numbers...
