My new data logger

[The Spectacle]

Wideband sensors are only as useful as the ECU that can read them. Having a wideband on a narrow band tune (such as the stock ECU) is non beneficial as far as inner workings of how the motor operates.

That being said, the ability to view the transitions between lean and rich may be of use to the average consumer granted there is some logic in the stock ECU that changes significant amounts of parameters based on this state (rich vs lean). With the Yaris, I don't know what that may or not mean.

In stock Honda's with stock 02 sensors it was always known that if you plug up a generic autometer AF gauge up, if the rating oscilatted between rich and lean back and forth, you were somewhere in the sweet spot for FE. Perhaps that is the case with the Yaris and this new gauge that you guys are talking about.

Long story short...I'm interested.
