Hahaha! lol ... And I would be surprised if the #2 O2 reading on your UG goes to 0000 when in lean burn only because that would be the same as deceleration fuel cutoff mode, when no fuel is being burned. I think the O2 reading will still bounce around and maybe confuse. So watch your short term and longterm fuel trim gauges too. They should go well into negative territory when you hit lean burn, first the short term reading and in a minute or so the longterm will start moving that way too. I hope that's helpful. Report back when you get some real world experience. I'd love to see what you learn.

After 3 months of driving on the new engine, I can say that I am very happy with the swap. Power band after 2700 rpm is far better than th D16Y7. Gas mileage is about 34-35 avg combine. My personal best on a single tank for regular commute 75% hwy at 65mph+ traffic is 38mpg. I am guessing if I go on a all highway long trip, I can get over 40 which is what I was expecting.
Long story short, if you are considering a HX/ D16Y5 swap, expect 35mpg and a lot more fun than the D16Y7. Make sure you use the proper wiring to safe time and headache. Good luck!!!

Congrats on loving your ride! Always important. Gotta love what you drive, if you have to drive it a lot. And I'm sure you can squeeze more MPG out of the HX engine when you want. One point of correction: the DX had the D16Y7 engine, and the EX had the D16Y8 that you refer to.

Y7, That's what I meant. Corrected and thank you!

And yes! If is am more careful, I can properly get 42-44 out of it!!! Mainly speed on I-5 just won't allow anymore slow driving in the morning commute.
