Sweet that’s good to hear I was getting nervous! And I thought I was in open loop I was asking how to get back close but I guess it did it on its own and yes that is my setup for a while! I am ready to tune it.

Yeah it all looks good. I'll keep an eye on everything as we go, but it looks fine so I don't see any issues.

Here is the first calibration. This is the 0* cam angle with vtec at 4500. Same datalogs like you've been doing, twenty minutes or so and the one third gear WOT pull. The 0* cam is kind of boring, so don't get discouraged when it doesn't feel strong.

So I have the Hondata app on my phone to monitor some things while I drive and I noticed the O2 voltage steadily goes from .3 or so up to between 4.0 and 5.0 and then back down. Does that sound bad to you.

The voltage will oscillate as you drive. that's how it sends it's reading to the ECU. It converts volts to AFR.

Yeah it looks really good for a start. Unfortunately I didn't see a clean third gear WOT pull from 2500-8600 in the datalog. We'll need to make another one with the clean third gear pull so I can finish the 0* cam table. You can take it for a ten minute datalog on this one, we really just need the clean third gear pull from 2500-8600.

Okay that one looks great. We will now move to the 15* cam angle with vtec at 4500. Go back to the twenty minute datalogs with stop and go driving, and a clean third gear WOT pull from 2500-8600. We'll see how it looks.

No problem on coming up short, I worked with it. Better to be safe on the road than risk it by running it out. We will now move to the 30* cam angle with vtec at 4500 again. Take this one for the same type of datalog and driving style. And tell everyone on the road to stay out of your way. Haha.

Yeah it looks really good. We will now move to the 40* cam angle with vtec at 5500. For this one, you can do a ten minute datalog, just be sure to get a clean third gear WOT pull as best you can. And try to run it out to at least 8000, tell all the people in traffic to move out of the way. Haha. Just kidding, be safe.
