If you bought it new it will have V2 tunes loaded

How can I check which version of the tune I have?

Not easy unless you start comparing roms in romraider.

suggest you just download the latest 2.063 tunes and load them into oft if your concerned.

If you logged rpm would help :-) maybe drop the wideband afr

IAM=0.8
you have some knock
the FLKC looks weird are you on a D00C or D00D rom ie the 2015 rom looks like the logging not working correctly would email shiv that log.

I think the logging on your rom not working properly would trust that log.

On my A001C, 2013 FRS, I am getting a IAM = .92 - .96 (Flux as temps do) with a wideband AFR of ~13.6:1 (Rather than the 14.7:1 I was taught we wanted back in the Hondata days of self tuning) while using the V 2.063 US 91 Oct tune

I'm still learning how to upload to DATAZAP though once I figure that out, I'll post a link to it for analysis, but I don't have access to 93 octane and can't afford the extra for the racing fuel (100 oct) that I have near me. Any ideas off hand?

On 91 octane you will see the iam drop slightly on occasions. It due to minor knock probably arround2000 to 3500 rpm.
You can pull a bit of timing out of the base timing B map.

few guys in california have done that try @JB86'd he might be able to send you map or at least the changes to the timing table. or you can do it yourself if you read the knock correction links below

Thanks. I've been reading just about everything you've had linked in sigs plus spent months of reading things before getting into this, so I'll definately read them again. Any and all help is very welcome and appreciated, so thank you for the information.

Lastly, I forgot to mention my "List of mods" which is actually small. An AEM intake (which has the sensor in the box to prevenet CEL pop on factory tune), A cut factory snorkle (Making for a lumpy ass top end and really crazy turbulence in the air) and a Manzo Overpipe ($40 and I was going to buy a header too, but haven't gotten around to it since getting the OFT)

My code is ZA1JA00C, I'm running the V2.063 tune and the tune file is the Stg 2 UEL 93 A00C.bin. I just hooked up my tablet to the car, looked under information and didn't see anything that mentioned D00C or D00D, where would I find that? I also just updated my Data to show rpm now, so I will be sure to take another log on the way home from work today and post it up.

sounds like oft needed update and template update, probably explains the dodgy log.

AEM intake will likely require maf scale, may be causing high fuel trims , and throwing off your afr , contributing to your knock

Any knowledge on people playing with removing the extra sensor that is provided in the AEM kit and running it off the MAF directly?

If not, this is something I may take into consideration and try on the V2.063 OTS straight off MAF. I am betting you're right.

I am using 93 octane gas with a K&N air filter and open flash header. Using V2.063 tunes, CAL ID is ZA1JA00C, The tune I have uploaded is Stg 2 UEL 93 A00C.

Looks like you have some crappy fuel as your IAM=0.8, usually it should be solid at 1 on 93 octane. and your getting some Knock correction at lower rpm .

However the FLKC knock values still look weird look like a problem with logging on hour oft. Send the log to shiv@openflashperformance.com ro contact the openflash guys on the phone

In the meantime do you think it's safe to drive with the tune or should I revert back to stock? I'll try a different brand of gas in the next day or two as I am at about a quarter tank now.

yes just try some different gas\petrol the stuff your on is performing like 91

I'm close to getting an uel header for the primary purpose of getting rid of the 4k vvt noise, would it be safe to load the uel e85 tune whole I'm still on stock header and e85 for about 2 minutes and Rev past 4k to see if the noise is gone or minimized at least. Then I'll flash back to the correct tune for my setup.

I've read reports of the uel tune getting rid of the sound but I just want to make sure before I drop $800 for a header.

E85 can be ran on a Stage 2 EL tune for stock cars safely if using the OTS stage 2 tunes. Please make sure your tune is solid and you run it for about 10 miles under 3500 rpm to allow for closed loop fuel mapping to complete. Once this is completed, you should be able to run WOT and do 3rd, 4th, or 5th gear pulls as you see fit.
If changing your tune, then let the engine remap / relearn the new composition of E% and then go from there. (It was recommended every tank you let it relearn before WOT)

Happy driving.
