Seeing the AFR on the first runs vs the stable 13.0:1 makes me feel better about their tune. Hell the oem map nealy allows you to fog it from the factory.
My Yamaha street bike has a pretty similar head and piston shape and getting under 12.8:1 is no help. Keeping the AFR at 13.0 to 13.1:1 from 5k to 13k and it sings making good power.
So what was your take on the puffs of blue, Rev limit induced? And you might just verify snow mode does take it 7,200....

Sorry to change subject really quick here but as I saw you guys talking about Torque Pro, I went in and bought it.
What widgets should I be using for common test besides the ones shown? Tried to find the one that detects knocks but is nowhere to be found. This readings were when car was idling.
Sorryfor interrupting and thanks in advance.

With Torque Pro, there are no widgets for detecting knock (KCLV and KFB). You'll have to use another third-party app such as OBD Fusion and also purchase the Toyota/Lexus add-ons in order to access these proprietary values.
It looks like you have all of the necessary displays to view what the ECU is recording in real time. Once you activate the datalogging option, you'll have the option to selectively choose which items to record (I believe the more items you select to record, the slower the feedback can potentially be). For my recorded datalogs, I tend to stick with AFR, Engine Load, Engine RPMs, IAT, MAF g/s and Ignition Timing Advance.

Do you have an intake on your car? It looks like you're lean on your LTFTs. Also I dont know if you have a 350, or 250 the MAF 4.4 g/s look a little high for idle.
Drive the car on cruise take a snapshot of the LTFTs should be a little close to 0 probably good on the rich side. I realised awhile back I bought a denso new MAF, and my LTFTS would be off while driving bank 1 was around -1.6 Bank 2 was adding +3.1 car ran like crap.
I then got a OEM denso one from Ebay used just to confirm.
My LTFTs where good then at cruising both banks are about -1.6 to -.08. Since then the car has always felt great.
I actually have 2 new denso first time fit MAFs. Both same results. One side would go lean cruising.
The original OEM spec MAF gave me back good equal numbers on both banks.

Has custom exhaust and KN drop in with cold box modified with a hole. Here a screenshot cruising at 22+ mph

You have too much going on there. You could get rid of the AFR(C), your fuel trims, coolant, vacuum, battery level and the calculated HP/TQ numbers are probably not any good. I would also change the maf gauge to include peak numbers.

My Bluetooth can't keep up with much. Like set the interval to 0.25 seconds and log more than 5 things and the log interval is more like 0.60 seconds.
Then again phone is also connected to cars system bluetooth phone / entertainment system too. I'll turn it off and see if that helps but previously on other vehicles it didn't matter.

2013 350 Torque log chart
Chart from Torque Pro, stock 2013 IS-350 @ 78,xxx mi.
Logging set to 0.20 seconds.
Rolling start at 4mph hits R-limiter at 86.x in 3rd.
Max MAF = 224g/s
Timing gets pulled back a good bit on the shifts...
Anyone have data showing how much the ignition advance gets pulled at Max load during shifts?

So, don't believe everything you see regarding Torque data.
I'll look on my laptop tonight, I have 4 different formulas I meant to try.

Hey red, I was looking at some of my logs and noticed my ignition timing at wot was always the same (excluding shifts). Have you noticed this as well? I am now wondering if the kclv actually matters or if maybe my knock sensor is bad.
