Good info guys. You can learn a lot by watching this gauge, it shows lots of OBD info all at the same time. Talk about distracted driving!! It is interesting to watch the STFT and LTFTs react, and for months now I've been paying attention. The Long Term trims are like an offset and add or subtract over time. Not very long they change with the temperature. If you start out on a cool morning, and drive home on a hot afternoon, the LTFTs will have adapted within an hour or so. Say your car needs more fuel for outside conditions. You can watch the short term trims stay in one direction and climb higher after staying higher in the + than negative it will add a positive to the LTFT then reset to zero. If the Short terms are still consistantly + then they will add another + to the LTFT and go back to zero again. So the LTFTs are an offset added to the short term trims.

Anyway, I think it's interesting and this post should probably be in the three drink minimum thread. LOL!! Goodnight.

This is all happening t keep the AFR at 14.7 not the open loop.
