OK, I checked out your log and it's outstanding. Fantastic IATs, knock contol is solid, fuel trims are great. You're hitting all your boost targets. Definitely a A+ from me.

Now let's talk about those misfired cylinder numbers.

I don't stop by this forum often so hopefully this is a learning lesson for all. For starters, your engine isn't really misfiring. If you were having any sort of significant engine misfire, you'd get a P0300 variant DTC.

What those misfired cylinder numbers represent are generally just noise events. Unless you see hundreds it's not even something you need to think about. Here's an interesting little tip ...

You had 8 "knock counts" at the end of the drive. Those are those noise events. Now notice you have 8 "misfired cyl" counts? 2+2+4=8. Knock count and the total Misfire cyl numbers are one and the same!!

Concentrate on knock control. If you get a flashing CEL, that's the concern not a handful of knock counts on a KTuner log. Hope this helps.
Thank you for taking a look at it, I was stressin when I saw those misfires recorded lol. But after reading similar questions on other forums and you confirming it, as long as its not hundreds at a time, it is normal. I appreciate your time.

I mean if you see 50+ clumped together in a matter of a few seconds, something might be going on.

You only having 8 on a 30+ minute drive is excellent.

Hey there- long time follower, first time poster here. Curious to hear from folks who went with a phearable 1.5 in their Aspec Tech, then either upgraded or have also driven a Type S.

How did the phearable compare? I’ve been on the fence on a Type S (and drove one briefly), but starting to favor having a more comfortable (paid off) daily with some extra ā€œoomphā€ over a full track car in disguise with a renewed payment.

I know the majority of folks recommend just sending it for the Type S given clutch, head gaskets, etc. but I’m not looking to put up 300+ hp out of this 1.5. Maybe 250, which seems manageable.

The Phearable 1.5 is a no brainer for a daily as long as you have access to 93 octane. More power than stock throughout, better throttle response, quicker spool. For a relatively small investment, tuning will transform your car's power. Will it be a Type S? No.

Think of it as an A-Spec++. Your smiles per gallon will increase dramatically.

Hey just adding some data

Vehicle: 2023 Integra A-Spec w/technology (CVT)

Total tuned time: 3months

Tuned miles driven: 3,000

Tuning device(s) used: KTuner V2

Tunes used: Phearable 1.5R

Fuel used: 93 octane

Additional related mods: PRL HVI with Fender Inlet, AWE Track Edition Exhaust

Problems/issues:
None

Driving style: Some aggressive driving around town with occasional highway driving. I had done a few races from a dig with local cars but nothing on the track.

Tuning experience notes: I think it really woke the car up and made it much more fun to drive

Figured I would reply again as I’ve put right around 30K miles on it since I tuned it

Vehicle: 2023 Integra A spec 6mt

Total tuned time: ~2 ish years or something like that’s

Tuned miles driven: 30k miles (52k total)

Tuning device(s) used: Ktuner v2

Tunes used: Phearable Stage 1.5R

Fuel used: 93 octane

Additional related mods: PRL HVI, Thermal RND exhaust, PLM downpipe and front pipe, Eibach Lowering Springs and Control arms,

Problems/issues: None

Driving style: Still quite spirited, I would say a god mix of causal and spirited

Tuning experience notes: Had a clutch slave cylinder replaced due to it squeaking after a aggressive driving session (warrantied), clutch definitely can have it moments slipping on map3 so I don’t really touch it, but stock psi and map2 handles nicely and without slippage. Additionally when I put in the PLM downpipe I didn’t do my research and it threw a check engine code so that I had to tune out but otherwise no issues there either.(For future reference or to save someone the headache, just go with the tsp downpipe, I regret it😪) Overall, no mechanical issues and the car is treating me right even during cold ass Chicago weather 🤭

I have a question. Some of you have mentioned you don't leave your KTuner plugged in. If you unplug it, the tune and everything still runs? Just need the device to log data? Change maps? and etc?

If someone can explain it to me like I'm five. lol I want to get a v1.2 KTuner but don't love the idea of leaving it plugged in. Appreciate it.

If I understand correctly - which I hope I mostly do as I’m planning Phearable 1.5R with a v1.2 soon lol - I believe all you lose by unplugging is data logging and map retention between starts (always goes back to map 1 on startup, but still able to switch as normal). Otherwise, same as keeping it plugged in. Again take with a grain of salt as this is purely based on research, not experience (yet).
