Track day was a success. Surprisingly, little cleanup on the F-Con maps were needed. I had pictured in my mind I'd be tucked away inside the car being anti social typing away on my keyboard the entire day. As it turned out the tune was at an already pretty decent starting point so it more about clean-up and validating my fueling and compensation strategies then rinse and repeat. My countless hours of street tuning paid off I suppose. Big thanks to @
illwillem for taking the captain seat while I played pretend tuner getting car sick with an unsafe laptop open in front of me going round and round on the edge of grip for several laps! (thanks dude!) Damn.. he's such a good driver! This exercise was huge because I can't get to those sections of the maps the way he can and studying the data logs on his session was just so different than mine during the first session. He's a much better driver than me and really highlighted the transitionary areas of the tune I needed to work on. I still have a few hours of studying his logs before I can call this tune done but it's all fine tuning stuff. Actually, I still need a tune for a super hot session so later in the summer will be interesting. For the record, I'm not sure if he likes my car at all but he's great at giving feedback. You'll have to ask him yourself haha.
By the way, for this track day I lowered/retarded overall timing another 3 degrees just to be on the safe side. I wanted to tune on 91 street gas and didn't want my normal track day 100 octane gas to influence things. I normally run 100 for all track days as added insurance. I can't wait to get on the dyno and finally try to squeeze some power out of this thing. At the moment she feels a little stronger than stock but with that signature ITB throttle response. Willem also brought his NSX so it was super helpful to get a feel for a stock'ish 3.0L on track back to back.
I feel really good about this ITB setup now and just time to round out the year. Tip on throttle from idle needs a tiny bit of work. I want it a little lazier from 0-10% throttle.
Unfortunately, I was so busy with "things" I didn't get a chance to setup a proper engine bay microphone, didn't do any lap timing, and was looking at gauges pretty much the entire time. I can't wait until this phase of the tuning is done so I can just focus on driving. The last time this car was on track was in 2017 for the Thunderhill NSXPO in San Francisco.
Here's a quick track video snippet. Audio is a bit lousy and doesn't really represents how the car is like to drive.

One last thing... the one bad outcome of the day was regarding my 3D printed PETG trumpets. I had my calibration off and I printed these rather in haste. My poor planning was rewarded with poor layer adhesion. I noticed these trackside and quickly took them off before even the first session. @
stuntman gave me some settings i'm about to try. Wish me luck! Airbox is next!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I can't wait for that finishing touch.

One more last thing! I liked the S2000 EPS quick ratio rack. I noticed I was a lot less fatigued, more relaxed on track, and the car seemed easier to dance with when it got squirmy. I feel like there are strong pros and cons but I can't see myself taking it off anytime soon. Still not sure how @
illwillem feels about it haha, but at some point you'll get feedback from @
stuntman. In my case, it opens up the option of going with 245 tires out front.
