No problem. It's looking really good. I made a couple small adjustments for the knock. Take this one for a spin when you can, we're getting close.

I'm glad you're happy with it.

No problem, it looks good. With the warmer weather things changed, so I made some changes to the temperature compensations. We'll see how it looks. Take this one for a spin when you can.

It doesn't show it on this data log, but it did show 1 knock count on cylinder 2 while i was driving at highway speed in 5 and 6th gear. Other than that it feels really good, idle is stable, and accelerations really smooth i like it a lot. gas milage is also a little better than before. Shits getting expensive yk.

This datalog looks great for the most part. Interestingly the part throttle fuel trims were on the positive side more than before. Go ahead and make another datalog when you can. And feel free to datalog only when you need to go somewhere. I do know how gas prices are, believe me. It cost me $100 to fill up a TSX the other day at $6.99 a gallon.

Damn 6,99 a gallon that's insane. i live in a area that usually has decent gas prices i think our 91 octane just hit around 5.50 a gallon.

Yep. I've never in my life had the gas pump shut off because I hit the $100 mark. There is a station somewhere here in California that is $9.99 a gallon. I think it's an outlying type station, but they've made the news a bit. I think Southern California is in the $8 range in normal everyday areas.

Yeah, in 2020 I took a road trip through the south and paid a high of $1.88 per gallon. Driving over 2000 miles in a week it was amazing.

So the datalogs looked great. Still positive fuel trims for part throttle so I added some fuel there. The WOT fuel was dead on though. We'll see how it responds to the part throttle fuel changes.

It looks like the fuel trim is a little bit better with this one. i got two datalogs. first one is mostly highway cruise with a 3rd gear pull. second one was a little bit of town driving.

Overall it looks good. It's just weird how the idle fuel is trailing off so bad. Make another datalog when you can and we'll see how it looks.
