Data Logs! Post them here.

you are supposed to use e85 and no less of that. and to make power with it you need to make lean and more timing

Hi, I have a log post request: could someone on K00G (or anything derived from it) capture a datazap log of five minutes of driving with typical log values (at least STFT, LTFT, MAF, Throttle) and add in what I believe is the learned LTFT target values table below?

; for use with K00G which has LTFT @ fff8d874, MAF @ fff89470

paramname = LTFT_bucket
paramid = 0xFFF8aae0 ; K00G
databits = 8

paramname = LTFT_target
paramid = 0xFFF8aac8 ; K00G
isfloat = 1

; _xL stores LTFT learning progress, higher values stabilize for 'done learning'
;; databits = 8 seems to be 193+ when learning is done;
;; databits = 16 would be .. 49152+, i think?
;; databits = 32 for 3221225472+, i think?
;; puzzling out the meaning of the learning progress bits is my next long-term project
; _x is the base LTFT for that zone
; 5..8 are the 'normal' zones, corresponding to the MAF thresholds in AF Learning 1 Airflow A/B
; 4 seems to be the 'popped the throttle to zero' / 'tip-out' compensation / zero throttle zone?
; 0 .. maybe .. seems to be the 'braking' zone, except sometimes it uses B1 rather than A0's learned LTFT?

paramname = LTFT_0L
paramid = 0xFFF80f60 ; K00G
databits = 32

paramname = LTFT_0
paramid = 0xFFF80f64 ; K00G
isfloat = 1

paramname = LTFT_4L
paramid = 0xFFF80f80 ; K00G
databits = 32

paramname = LTFT_4
paramid = 0xFFF80f84 ; K00G
isfloat = 1

paramname = LTFT_5L
paramid = 0xFFF80f88 ; K00G
databits = 32

paramname = LTFT_5
paramid = 0xFFF80f8c ; K00G
isfloat = 1

paramname = LTFT_6L
paramid = 0xFFF80f90 ; K00G
databits = 32

paramname = LTFT_6
paramid = 0xFFF80f94 ; K00G
isfloat = 1

paramname = LTFT_7L
paramid = 0xFFF80f98 ; K00G
databits = 32

paramname = LTFT_7
paramid = 0xFFF80f9c ; K00G
isfloat = 1

paramname = LTFT_8L
paramid = 0xFFF80fa0 ; K00G
databits = 32

paramname = LTFT_8
paramid = 0xFFF80fa4 ; V00C
isfloat = 1

My testing with V00C w/ S20G dipi ratios on Cal91 shows {0, 4, 5, 6, 7, 8} = { +3.1, -3.3, 4.8, 2.0, 4.0, 5.0 } and LTFT stable during a WOT pull. The log is missing a great deal of normal values, but for the curious: https://datazap.me/u/callisto/log-1754135697

Hi all,

https://datazap.me/u/jm22/2025tommv0...&mark=53-69-66

Here is my log. NA with Power Blocks installed. I hope you can give me some feedback and help me fine tunning a bit. I understand that:

• AFR at 3k-4k rpm is not consistent, the tune is too "Lean"
  
• AFR at 6k-6.8k is a bit high (11.9-12.17), the tune is too "Lean"

Is that correct?
Should I just take MAF sensor scaling table and multiply every value by 1.02, for example? And increase timing a bit, since flkc is 0

thanks in advance

Data log from a gen 2 BRZ. Tuner sent me a base e85 tune which I was testing out. A little concerning to see IAM drop to 0.61. Even more confusing b/c I barely see any knock correction and there doesn't seem to be any negative FLKC.

Car is stock other than a catback and GR intake. Tested at ~3000 ft elevation. Any thoughts? TIA!


(Note I was part throttle in that log due to IAM but here's another log where I was going full throttle

Hi,
I think I finally nailed my OL, after 4 scalings using the MAF scale app:
https://datazap.me/u/jm22/20260214to...-7-12&solo=3-6

I will make the >4V just a tiny leaner

Timing goes up to 27, I wonder If If there is room for more or if I should leave it like that. My car is NA, RON98


Regarding CL:
https://datazap.me/u/jm22/20260214to...=0&data=1-9-10

I plotted the LTFT, see attached. I adapted the curve accordingly, now it looks like this (see Scale4 curve). I wonder if I should smooth out the transition (~2.9V), or if it is fine like that

any help welcome

[tomm.brz]

it looks good
you can keep it the maf scaling like that
About ign advance, the values depends on many things, included afr and pi% so we can t judge absolute values
what you can do is try raise them until knock appears

Throwing this here since I'm also going to post in my build thread. I found Vital log viewer recently, it's super fast and reads CSVs. Just wanted to share in case anyone wanted to try something that actually is pleasant to use. It does cost $$$ for a license but I took the dive since I'm sick of megalog viewer and other crap.
