I'd scale your MAF back a bit, or possibly increase rlmax
It looks like you are hitting your spec load, and the ECU is capping something.
I'll have to dig through the FR.

Quite possible... I'm gonna try to scale back the MAF again when I have some time... I also want to try fueling via LAMFA as well...

Here is my decode of the calc of rl (load) based on the FR. rl = rfges - rfagr
rfagr = rfges * (250 hPa)/ps (MAF path)
rfges = pbr - pirg * fupsrl (MAF path)
pirg = Lowpass(pirgro) * fho (internal residual gas AGR)
pirgro = (select a prg based on sumod)
from PRGNM, PRGSUNM, PRG2SUNM, PRG3SUNM (dependent on rpm)
fho = (correction factor based on ambient pressure)
fupsrl = Lowpass(psrlro) * ftbr
psrlro = (select a url based on sumod)
from URLM, URLSUNM, URL2SUNM, URL3SUNM (dependent on rpm)
ftbr = (correction based on modeled combustion chamber temp)
from CWTEMPK, FAKTABGM, FWFTBRTA, FWLKFTBR
(dependent on ps, tmot, tans, etc).
pbr = ps * fpbrkds (MAF path)
fpbrkds = KFPBRK -> KFPBRKNW (based on fnwue - cam position fader)
ps = psfg+psagr (MAF path)
psfg = sum (0->psmx-(250 hPa)) (rlroh-rlw)*fvisrm
fvisrm = KISRM * ftsr * 10.13
ftsr = (tsges + 273)/273
tsges = tans (SY_TFA=false) (?IAT downstream of EGR?)
rlroh = rlfgroh (MAF path)
rlfgroh =
if (B_dk & B_lm) RLNOT (88->21 for rpm 480->2000)
if (B_negldrg | E_lkvdk | (SY_EGFE, !B_hfm, etc) rlfdkroh (speed density)
if (B_mxrlroh) rlfdkroh/fkmsdk (lambts < 1, rldkofk-rlflmroh > DDRLDKZU)
rlfdkroh = (mste+msdk)/(nmot*KUMSRL)
mste = (tank ventilation airmass in intake)
msdk = (air flow over throttle plate)
fkmsdk = integral(fkmsdkg)
rlflmroh (MAF path)
rlflmroh = (mshfms+mste)/(nmot*KUMSRL) - drllad (MAF path)
drllad =
if (B_edsl) 0
B_edsl = pvdkds>PVDKMX (dependent on rpm)
else pvdkds-lowpass(pvdkds) * KVLAD
pvdkds = MAP output after DSLGRAD/DSLOFS, max 2560
(boost pressure actual)
mshfms = MAX((mlhfmm - MLOFS) * KFKHFM, MLMIN) (MAF path)
mlhfmm = mlhfmas/anzhfma (windowed average of MLHFM) (MAF path)
mlhfmas = SUM(MLHFM)
anzhfma = counter
SY_EGFE
Bit0: HFM vorhanden (B_hfmv) 1?
Bit1: Drucksensor hinter der DK (B_dssv) 0?
Bit2: Drucksensor vor der DK (B_dslvh) 1?
Bit3: Umgebungsdrucksensor;Pu-Sensor (B_dsuv) 1?
Yea. It's a mess. I'll have to think about possible sources of that notch. If you really care, we may need to log a few more things  |

I'm down for whatever...
I need to get Setzi's logger setup and running...
Do we have a decent/default config for all the variables I should be logging?

why do you start with a lower WGDC, arent you on aftermarket gates?
I think your low DC during spool up is hurting.
as for that load bump, no idea.

Try loosesning up the torque limit tables --- solved my torque intervention issues. If you loosen these up and your dip is replaced with a throttle cut and Torque Monitoring Limit Exceeded code then I bet you need to scale back your MAF.  From what I can remember yet. |

Bert, according to the FR, the output of RLVMXN/RLVSMXN only goes into KFMIOP if SY_TURBO is false! If SY_TURBO is true, rlmax goes into KFMIOP. to generate mimax with FMIVL.  I can find no other reference to RLVMXN anywhere in the FR! |

I can find no other reference to RLVMXN anywhere in the FR! I noticed this too, however, it worked in my current tune. I had a weird load decrease which was eliminated by addressing those 3 tables. Another instance of black magic - I know... the appropriate variables need to be logged to confirm exactly what is going on. |

My next move is to underscale my MAF some more to bring my load range back to normal levels... but I will keep that in mind for sure if I am still having issues with timing dropout's and TQ intervention.

Timing looks fine to me.
You could probably add a bit more fuel.
Need a wideband to see if your req AFR is lining up right with actual.

yeah I'm still only using my eyes to "log" from my WBO2 gauge... for the most part it looks alright... can use some more fuel in a few places...
timing "looks" ok, but not great... seems like the load has shifted and now it's running more timing in the low/spool end and less up top towards redline... so I def need to fix that.
Also the KV are about the same as my other tunes but KR is higher which I believe is tune related (not necessarily actual knock).
Either way looks to be a promising start... definitely needs more messaging...
