OFT 4.03 stg2+ tune
RON95 fuel (only option in this country)
Oil catch can

Too much negative FLKC and too much negative LTFT.
Bad gas mainly causes FLKC but is that much normal just because of ron95?
What causes that much negative LTFT?

Do you think is there any problem beside bad fuel?

Same call ID is mine and when I first used OFT maps MAF scaling was way off, advance timing too and with Greek 100RON I had quite a lot of detonation (flkc) but not as much as yours, overall K00G OFT maps I could say won't work with this car!
It is normal such knock correction with 95RON, try using octane booster or lower advance timing, even with our medium quality 100RON I have some flkc.
Tor's AVCS maps for Gruppe-S headers, posted in his thread, improved overall my car while knock behavior is reduced not increased from the extra degrees VVT!

Better follow tomm.brz suggestion or contact a friendly tuner of the forum that can help your with the tuning procedure for a small donation!

Hey, I am 100% unqualified to read logs. I just swapped in a new to me lightly built engine after I spun a bearing in my old one (Oil mishap). I'm using FBM's Turbo (Garret T57), 550cc injectors. The block is forged, running upgraded springs and valves, but same compression. I am running the same tune from my old engine, and I just want to make sure everything is running fine. I sent the logs to my tuner, but he is pretty busy lately. Anyone care to take a look and tell me what they think? In the zip below there are two 2nd gear pulls.

Sorry about that!

looks reasnoble

highest boost is 0.6 bar or about 9 psi
but your only at about 40% throttle

You are starting to get a little knock about -1 but your not pushing it hard, assume your on petrol 91/93 ?



that knock will likely get worse as you go full throttle so keep and eye on that (ignition correction fine) and the Advance multiplier it should be 1 with minimal knock.

AFR on petrol should be round low 12 or high 11 at full throttle on petrol

Thanks for taking the time man. Its been getting Cold, I can't keep the tires planted in 2nd. In the year my car was garaged I forgot If I had it tuned on 93, or 91. Do you think putting 93 in it would solve the problem (If it was tuned on 93, or even tuned on 91?)

If you have access to 93, use it. Engine was designed for it and will help with the knocking.

If your tuned for 93 then you must use 93 or better octane fuel

If your tuned for 91 then you can use 93 as it better fuel

but dont use 91 in a car tuned for 93 especially boosted cars

@steve99 Could you take a look at my log from the tail of the dragon run I went on. im on 93 Oct Uel header and N1 Catback

looks fine

iam dropped once to 0.88 looks like you got hard on throttle at 2000 rpm but it went straight back to 1, rest of flkc corrections less than -1 so thats fine .

Yeah it was a semi difficult road in my opinion Was probably after a downshift then wot on a straight. also mild quality gas and high elevation im assuming all played a part? Thanks!

[pym19109]

I have -1.3 flkc in mid-rage about 5k-6k, 0.5-0.7 load with low-half throttle (spirit driving). Should I pull some timing in this area or is it ok to leave it like this ?
I'm running e85 but not good quality compare to US e85

Getting positive FLKC which seems kinda odd. IAM starts at .7 (OFT sets value to this if I remember right) and slowly goes up over 2 pulls.

Open Flash Tablet Stage 1, 91 octane. Car is stock engine wise other than a drop in filter.
