My n75 is working, we can see duty doing the job and the boost decreasing. I guess.
The weird thing: this log was made in 3th gear WOT like you told me to do. This entire time I'm pressing the gas to the floor and you can see the throtle angle closing down... The boost is cutting because of throttle cut.
The car is running good until 4krpm, and then it "chokes" and it's really hard to get to 6k+ rpm. Any clue?

is this a stock map? Your requested boost looks fairly high for a stock map.

Nope, still my "tuned" file that I'm working on it.
I'm fighting with me7logger... it's blowing up an error randomly... can't log things right yet.
Did a little run and logged the pieces when the car "chokes". CondLambdaForPartProtection (B_lambts) and CondEGTForPartProtection (B_tabgbts) are both triggered (1). But I guess these 2 things only affects my fueling.
My car has no misfires and I can't see any ignition retard due knocking. Both values show as 0's. Knock voltages are below 10V. These can be wrong in higher RPM's, but for now still can't pass 4000rpm without the car "choke".
The problem stills the Throttle that cut's while my gas pedal still's 100%. Maybe the problem is MAP? I'm for sure hitting boosts near MAP limit (2550)...

So have you read the s4wiki article on throttle cut?

Rpm 4480
Actual boost exceeds requested by more than 300mbar! Throttle cut triggered as a result.

my suggestion is load your stock map and make sure you have no issues ie no throttle cut etc that way you will know whether its hardware or not

Thanks for the right path nyet. Now I see that my boost are getting over 24psi (MAP limit) and I really need to be carefull (uncontrolled boost)... Thanks artite that point me to load original file and make things right without raising boost. You told me this twice. This is what need to be done in first place at all. Now I see this clearly. My turbo is a k04/e05, and my original car PID is trying to deal with k03s wastegate. This is the problem. K04/e05 is based on k04-001 with k04-020 internals (TT225 one). So guess what I did: copied TT225 PID maps and did a little bit of math (because the maps axis values isn't the same), and tchadám: the car PID is now working fine with "original boost maps". The N75 cycle is doing fine and the ECU can cantrol boost fine now. The car is smooth until 6000rpm now. But another things happened  The ECU is throwing DTC: 17963 Charge Pressure: Maximum Limit Exceeded and the logs still showing that past 4000rpm the car is lowering the boost request and the N75 is working to decrease boost (without throttle cut), even LDRXN and KFMIRL remaped asking 22PSI. Now it's time to read more info... |

Hey guys, attached is a 4th gear WOT log I did right now... can't go far 4800rpm because the road ended... For now it's what I can do.
You can see that in 3600RPM my requested boost start to decrease, and this is the problem. I really doesn't know why it's requesting less...
Attached is my LDRXN and KFMIRL. I'm trying to request 2500mbar ( ~ 22psi) past 4000rpm, so I really doesn't understand what I'm doing wrong now... The throttle is cutting again because I'm delivering too much more boost (I known, that's the idea now... I don't want to tweak PID again, because this loweringin request boot isn't what I desire).
LDRXNZK is exact copy of LDRXN. I have FF'd KFDLULS. KFLDHBN is FF's too.

that is NOT a csv, it is a cut and paste from excel.
Please attach an unedited csv with full headers.
Also, don't bother with VCDS, you're not going to be able to do any real further tuning w/o a proper logger

nyet: nefmoto logger neither me7logger are running fine here... I guess my obd2 bus is high loaded... the log starts and then both softwares stops at random... lost comunications I guess... :/ I'll try ECUx and see what happens.
Attached .xls now...

Not an xls either. the original csv please.
ecuxplot can only read real csvs, since there is no telling what people do to their xls' before they save them.
In any case, make getting a real logger working a priority.
Also, 3rd gear is fine, although 4th might be easier if you are only trying to log ramp.

Your LDRXN is ridiculously high at low rpms. Please read up on positive deviation. |

Found the problem with loggers.... my notebook is a IBM/Lenovo with an accelerometer who stops the HD when the latptop shakes. Disabled this feature and the logger runs fine. Attached the first log I did to try, so no long WOT's... just a test. Found 2 problems in my car: EGT sensor probably broken, because always displaying 1035C and coolant temps getting so high that the corrected load decreases (causing my requested boosts to drop). The car is cutting throttle when temp gets high and then when it runs from 100 throttle to 30 (cutting throttle to decrease too much boost) the KFMIRL map get's in place and try to get my load even down (max load at 30% is very low) causing the choke's. Will fix these 2 issues before trying any more mods on the maps/ECU. btw, loaded this file on ECUx plot and your tool is really great! Please if you have comments, feel free |

Another lesson learned: you will never play nice with stock injectors No matter what turbocharger you`re talking about, fueling is the first thing to increase before increase boost The temperature problem was because my car is running extremely lean with high boosts (Thanks to ECUx plot I can see this clearly). Injector duty cycles extremely high. Did a run with 1.2bar max and I can go far to 6000rpm without chokes, but again, the car start to starving out at 4.5k and throttle cut at 6k. Sincerely, now I can see this things and I`m wondering again about the tuners I paid to get my car chipped and they never told me this stuff... what a pirates. Owwwww. Increase boost and let the sponge bob play! |
