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?

Code:
; 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
