Running Stg 2 UEL with 93oct. Stock intake, stock air filter also. @steve99 or @Wayno can chime in? Thanks

Do some 3x 3rd gear pulls to get meaningful results. One pull is nothing.
Also you run too rich + LTFT is way off.

+1 on what rezi said its running way rich 11.2 and below what sensor is calibrated too on oft tune, and ltft needs work. Basicly maf scaling will fix it, assuming you dont have any intake/exhaust leaks

I checked for leaks, but seems everything is fine. I will try to get more pulls, you think the car can run more aggresive tune like ofh tune?

Without fixing the AFR and adjusting the MAF i wouldn't consider to try any more aggresive tune.

Check your O2-sensor if they are tight. Otherwise if you are 100% sure there are no intake&exhaust leaks try a slightly leaner MAF-Scale.

Ok. I will check on a muffler shop and do a leak test. Im using 93oct, if i use 91oct would give me different reads?

Hi Guys,

I am running on Toemi UEL, Milltek O/P and F/P, k&n drop in and OFT Stage 2 UEL. 91 gas.
I recorded logs for the very first time today and saw that IAM is dropping to 0.88 sometimes. Is this something to worry about? I'm bringing this car to track from time to time but all previous track days were on stock car. I'm trying to understand is it safe to go on track with this config.

Here's the log:

Here's the first E85 pulls for the season. The two full throttle pulls are both in 3rd gear. Wayno's e85 tune. Tell me what you think and what can be improved on it. Would really like to fully optimize this car.

Wow. Lowest I've been on E85 is 40-45, curious how you'll find it on the 20-30 days we've got coming up.

hahah tbh, it's not too bad. I ran it until I couldn't take it anymore before winter and starting is a bit interesting. But the good thing is she loves the cold air haha. I've had the intake temps down to the negatives and damn does she pull harder than when temps are ~40. I'm just starting the season earlier so I can fine-tune the tune before race season

Multiply 3.44V and above by 0.96.

Am I ok?

Can anyone decipher the issues i'm having here? my STFT is all over the place, LTFT is +-5%, and i'm not sure if the distance between my command AFR and AFR is safe, it varies quite a bit. Most of the issues seem to be while cruising, for example at one point i'm just coasting at 5% throttle and the STFT is all over. Any help would be greatly appreciated.

Mods include:
Borla Header
HKS Front pipe
HKS catback
OFT running stage 2 UEL tune,
Stock intake

Diagnosis ---- you don't have a problem.


STFT is supposed to vary widly in closed loop, and will be zero in open loop.


The LTFT of =/- 5% or less is good.
commanded afr and measured afr are close, maybe 3% rich top end but fine
IAM=1
no knock flkc or fbkc


all good
