ok so im having a problem car is a corrado with a 1.8t swapped in and ko4 xl billet turbo awic 3" turbo back high flow manifold. current tune uses a late model vr6 maf sensor and housing 52lb ev14 injectors. in first and second gear at wot i get a power cut/ boost cut im running 25-30psi on this setup. here is the log please let me know what else i should be logging, i tried to figure out whats happening but i feel im missing some variables that will tell me. i can see timing is all over the place so i assume its riding the knock sensor. also this is a completely stock junk yard motor car is not a daily just a toy dont care if the rods bend break ect...

logs don't include boost actual, timing corrections, etc. I can't tell where it's cutting in the logs either. Get logs with more variables.
Assuming you are making 25-30psi @4,500+, the Mass Air Flow looks way low.

i will post another log with those variables, in the log you can see the maf @5360rpm the maf drops from 144 to just 44 rapidly. also i thought that i was at or a above the limit of the map sensor so i wasnt sure it would be useful |

30psi is alot but as this isnt a daily i want the capability to run high boost at the track. it will taper to lower twenties so not to redline, i know the wastegate duty cyle goes to 100% in the log at the same time the maf reading drops from 144 to 44 gps. i will add more variables and log some more, thank you guys appricate the imput |

30psi on a K04 is going to have extremely high intake temps. Especially in a track environment assuming you run in the summer. |

Sounds like floaty valves and melted Pistons. Stock manifold and small hot side choke so bad. Just really wrong.

So many assumptions here and people didn't even look at the log apparently.
IATs are below 45 deg C.
Add these to your log config and record another one:
wdkba
wped_w
ps_w
pu_w
pvdks_w
msdk_w
dwkrz_0
dwkrz_1
dwkrz_2
dwkrz_3
EDIT: Your requested boost is at ~18psi. When you go ~200 mbar over that - you will get throttle cut.

thank you sir, im running an air to water intercooler so that keeps intake temps in a decent range. also i do have a high flow manifold and 3" turbo back no cat. i can understand this is extreme but by logging passes and checking plugs you gamble less. im planning on drag racing occasionally ad using the tools i have. |

here is another log, i adjusted ldrxn/zk and pulled some timing out of it and still have a cut. it is much clearer in the logs but im drawing a blank. i must be missing something because i can see requested boost drop out completely

LOL at your actual boost.
WTF are you doing?
You're going to pop a turbo or blow your motor pretty quickly with that shit tune.

the 001xl is a clone of the f21 1:1. the small frames choke out very quickly egts skyrocket and turbos fail quickly. whats ldrxn and zk look like?

Irrelevant compared to the mess that is his actual boost. Unless he uses the 5120 hack this project is a still born waste of time. http://s4wiki.com/wiki/Throttle_cut |
