Hey guys, this is the first topic im creating in this forum so im sorry if im wrong in anything, but here we go.
First of all im new to this, my golf is the 1st car i try to modify, I have been following the stage 1 community project with some success, but also a lot of struggles.
They are on Audi, AK file, software 03, im on VW HJ file software 2
I originally copied the diferent maps with WINOLS from an AUQ 032HP file as is the same as mine but 180hp, and i instantly felt a diference in the car, feels better, faster, harder, but i want more.
My car is from 2002 so it has full electronics, and a K03 - 053 turbo (K03S without muffler)
Originally was between 6 to 8 psi depending on the day and temperature, after my change it was boosting 9-10 psi.
So after a lot of reading i started to copy values from the community's project into my file, (i want to keep it that way so i dont have to change any eeprom data)
After all the relevant maps have been copied, the car is even better, boost spikes to 15-16psi and holds 12
i would like to keep the 16psi spike and try to hold 14psi steady untill it drops off to redline
The car feels good and fast, no DTC's .. I also have removed N249 and SAI, but i Kept my PCV and EVAP in, the 2 removed are also coded out on my file, also Rolling pops and bangs, and a Hardcut, car drives with no issue whatsoever.
My main concern is that im doing something wrong as the car is developing somewhat a Hunting Idle, and even tough it pulls fast, it doesnt pull Hard sort of, maybe something with the timing or the fueling isnt right, like when it spikes it pulls fast and hard for 1 or 2 sec, and than it tones down, the speedometer still moves fast, but it feels like the torque dies on me.
After some trouble Logging, (MK4 are known for that) i managed to get some with Me7 Logger in 0x00 Slow mode.
So i will leave my Original File (150hp)
My modified from AUQ (180 Pops and Hardcut)
And my stage 1 V3 with should be close to 200hp
My winols .kp file
with some logs of the stage 1
Everything in the car is AUM stock,
(THIS IS NOT A RATE MY TUNE POST)
I just want more experienced people to take a look at it, and hopefully help me and guide me in the right direction as i do want to learn it properly
Eager to hear back from you guys, hopefully im on the right track

fueling is off by about 10% on WOT
also you are not anywhere near 200 bhp. I'd bet rather 170
also, you can play a bit with timing.
idle hunting - do you have any kind of cone filter or modified maf? It looks like hfm reading on idle is a bit off.

Stock Filter and Maf The Car is 100% stock parts, 231000Km Recently changed timing belt, water pump, did coolant flush, upgraded coolant flanges to aluminium, fixed some vaccum leaks, and thats about it other than that its all stock. Fueling 10% off on WOT, by that you mean, its running lean i supose, so i have to enrich it? Im sorry for the newbness, i am really trying to do this on my own, as i see a lot of people just come here and be like "Stage 1 pls givv" XD |

You are out of injector up top end because your request is very rich.
You should do a clean pull from 1500 to redline in the 3rd gear.
your log is not very usefull if you run 2nd gear (low load, very short time) starting above 3000rpm.
Would recomment to log stock file at first to have a base for comparison.

Okay Got it, ill do that and come back to you guys. Maybe Later as for that i do need to hit the highway once traffic dies down, 3rd gear goes fast, my back road isnt big enough |

Double post again, Sorry
I cant add files to my previous post.
I have also tried a friend of mine's tune in my car (copied values)(Same car,same year, same ECU), his does more boost, but again im not hitting my target AFR, why could that happen ? Too much boost ? or not enough injector again ?
and i think the ECU is pulling 2/3 Degrees timing top end due to knock.. also my timing tables didnt change much, where he is running -12 high end, but one thing is for sure, his map on my car feels faster, now my question is, wich one do i refine ??
Here is the Bin and 2 Logs, 1 is 2nd to 3rd gear, the other 3rd gear, but again, not clean log as i ran out of road.. (as in have to brake, the treeline is approaching fast)

You can graph injector duty cycle in ecuxplot.

stop driving like this One of your logs contains idle at the beginnen. Your lambda control is at 10%. On wot you dont have fuel at all. your lambda control is maxed at 25% all the time. your requested fuel and actual fuel should match. You should revert everything back to stock and log again. check the fuel trims, pressure test everything from the turbo into the combustion chamber or even better smoke test everything with an autel smoke leak device. Then start with only fuel changes in your tune but dont touch ignition or boost. After all this you will notice that your fuel pump is weak. Buy a fake dw65v for 100bucks and buy a new fuel filter. Ultrasonic your injectors or just buy new ones. I dont recommend to buy bigger injectors because this will only create new problems with the software for a novice. The fuel request in this file looks way more resonable than in your first file. You have to learn to read a log with ecuxplot. At 3000 you have 1bar of boost but ecu has to add 20% more fuel because your fuel system cant provide it. Its a 213000km car  |

You refine yours so you actually understand what you're doing. If AFR doesn't match, sort that first. |

Here is a log i did 20min ago, its 3rd gear but it doesnt go to redline. So far AFR is following the desired, and no knock as i dont see any timing retard.
i would like to increase the boost 1 or 2 extra psi, but i have a doubt, if i do that will the ECU compensate for fuel to keep that AFR as long as my fuel system can provide it? if not, what map is responsible for that ? i dont mind the boost tapering down at top end, but id like to increase it in the mid range a bit, but my ijector duty cycle seems linear, is there a way to make it inject more at mid range to go along with the extra boost ?

That Log goes from 2000RPM to 5800, The Car doesnt pull anymore after 6000, Im still trying to figure it out, but at 6000 feels like i hit the brakes, So that logs is m Redline technically, I do have Optimal Ingnition angle table retarded to -12000 aroud that area, could that be it ?
