Yes, I've just increased the values (black line) slightly versus the old (red line) values and will see how the boost changes.

I'm also going to slightly lower timing around 2000-2500 rpm and increase a little around 4000-5000. All timing changes will be on the order of 1-2 degrees.

Updated results:

Nef4 (previous - yellow) vs Nef5 (current - blue) Boost

Here's the timing change progression plotted out.

Please post logs, and ECUxPlot graphs if possible..

IDC is maxed, so I think we are good there. Don't think we can do much more boost on stock injector/fpr.

Timing looks good.

Don't know about the rest until i can look at the logs themselves, in particular, PID stuff.

Added the CSV to this folder:

http://www.myaudis4.com/tuning_images/nef5/

This has the charts:

http://www.myaudis4.com/tuning_images/nef5/charts.html

IDC is <85% @ 5500 rpm

Whatever you are using to process the csvs... please stop. You padded it with commas.

Even worse the first line is

Code:

1,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,

which makes automated parsing of that csv impossible.

PLEASE at least try to open it with ECUxPlot (to verify your munging didn't mess anything up), since that is what others will be using to visualize the data, not hand cutting/pasting into excel, or similar silliness.

Also, at this point, we are going to need the rest of the PID variables, since we are underboosting...

Code:

ldimx_w         , {BoostPID-I-Max}                  , 0x382740,  2,  0x0000, {%}       , 1, 0,        0.005,      0, {Aktueller Wert zur Maximalwertbegrenzung I-Anteil LDR}
ldimxak_w       , {ChargeLimitPID-I}                , 0x382742,  2,  0x0000, {%}       , 1, 0,        0.005,      0, {Aktueller korrigierter Begrenzungswert I-Anteil LDR}
lditv_w         , {BoostPID-I-Result}               , 0x382746,  2,  0x0000, {%}       , 1, 0,        0.005,      0, {LDR, Tastverh�ltnis vom I-Regler (word)}
ldptv           , {BoostPID-P-Result}               , 0x382748,  2,  0x0000, {%}       , 1, 0,        0.005,      0, {LDR, Tastverh�ltnis vom P-Regler}
ldrdtv          , {BoostPID-D-Result}               , 0x38274A,  2,  0x0000, {%}       , 1, 0,        0.005,      0, {LDR Tastverh�ltnis vom D-Regler}
ldtvr_w         , {WastegateDutyCycleBeforeLin}     , 0x382754,  2,  0x0000, {%}       , 1, 0,        0.005,      0, {LDR Tastverh�ltnis vom Regler}

This illustrates our load/boost issues... phila, can you comment?

Also, maybe need to log ldrlms_w, fupsrl_w, and pirg_w... I don't have locations for any of those Sad

TIA

Note that ChargeLimit etc. doesn't have units... probably need to hand edit the ecu file to get it to report mbar... either that or the log is kinda screwed up so ECUxPlot is having problems extracting the units properly. Need the original .csv to make sure.

KFTARX and KFLDHBN

fldrrx_w is 1 throughout, I imagine coolant temp remains below 117* c, so all rlmxko_w intervention is from KFTARX.

There is also load intervention via ldrlts_w (KFLDHBN).

rlsol_w does need to be added to the config file though.

Relogged with the additional variable. CSV in this folder, all 4 3rd gear pulls are relatively short.

Charts of a few variables

Made a couple minor timing adjustments that I will capture and add to this post later.

Awesome! Thanks Jeff!

Can you run the next set of logs out to redline? We need to see how close we are to injector max..

Here's the latest stuff including full csv. There are a couple short third gear and at least one second gear pull.

http://www.myaudis4.com/tuning_images/nef7/

Here's some charts:

http://www.myaudis4.com/tuning_images/nef7/charts.html

The timing changes. On the left side are the original tables and on the right are the current values. For KFZW2 I lowered the values slightly to try and eliminate the ignition retard that was occurring around 2000-2500 rpm. For KFZW I raised some of the timing values to try and have a smoother transition around 3500-4000.

Does anyone know what boost the APR tune pushes? Roll Eyes

Too bad there is nobody here with logging software that can log an APR car Tongue

Generally 15-16psi, IIRC.

Nevermind, i found the answer on his website. He just has it and that's fine.

You can log APR.

I believe this is as far as the Stage 1 tune will go. The thought was to start a Stage 2 tune discussion and use that thread to address some of the more advanced topics that surfaced during the Stage 1 tune.

I'm swapping to different turbo's so I won't be logging the Stage 2 changes.

im kind of surprised the apr tune stage 1 killed our tune in the acceleration department ......i think what is killing this tune is timing was barley touched and could use some more......

Uh. 11 psi vs 16?

I don't think we should stop here for stage 1.

IMO we need to massage HBN, bring up peak req boost to 15 or so, possibly iron out the VVT load->boost wrinkles (i'm sure purists will cringe, but IMO I don't gaf), work on fueling, then timing.
