I am looking for a good, tested tuning file for a Golf Mk4 2002
I have been trying some files around the internet (comparing them in winols to my stock ofc) to see if they might work
But since im new to this, i have achieved some decent results but im not happy with it, either it pulls hard but my fueling is not okay, or my fueling is ok but it doesnt pull hard, other instances turbo always overboosts because i think im not setting up the PID correctly

I am looking for a good tested file that works and its safe, I have Cables, and i have my files patched to do Running LOGS

(MK4 have a problem where you can only connect with ingnition off, or cluster fuse off, but with the correct BAUD, and 3 values changed in the files you can connect VisualME7Logger with the engine running)

My Goal is a Stage one of around 210Hp

Turbo is K03S
Stock AUM Engine
ECU 06A906032HJ
HW 0261207436
SW 362287

Does Anyone have one ?
If not, do you know of any trusted File Service ?
I know about Revo but have also heard it dies at high rpm ,APR tunes seem better in that area, but what else is there on the market ?

Original File Read with Nefmoto


My Engine has Cat Delete, N249 and SAI delete, with a block off plate on the block and i coded out on the files i tested

My problem is im having fuel issues, i see many times over a K03S will remap to 210, but my question is, can the fuel keep up with that ? or all of those tunes are running lean ?
I am on a 3 Bar Stock FPR and injectors are i think 312cc or 317cc .. Im always aiming for a 12.05 AFR and a max of 18PSI, is that too rich ? Too much boost ? maybe thats why it cant keep up with it, On my logs, either it goes lean, or has Knock retard, preferably i would like to have a Flat line of Knock retard but because i never seen a good tuning file, i dont know if they are flat, or if 1 or 2 degrees of retard are acceptable .. Help me please

Edit: i live in Belgium, i always Use RON98, is the max around here
Edit 2: I also have a Silicone Inlet Pipe, with a Cone air filter, my stock one was collapsing under high boost

I've sent you a tune in messages

Okay so i compared the file with winols, to the ones i have, i was surprised to see how much timing advance there is in this one, so i went in increments with the tests, my conclusion is, that the turbo is too high, together with too much timing advance after 4800 RPM, the fueling cant keep up with the requested, Air Intake temps climb drastically, and the Ecu is pulling at least 6 degrees of timing in stages, so it goes like -2, 1 second later -4, 1 second later -6, after that i stopped accelerating. i will try to lower the turbo pressure in hopes that my fueling can meet the required AFR as well as removing some timing.

My question here is, what maps did you use for the turbo, because i boosted 20 PSI with LDRXN at 180, still boosting 20 PSI with LDRXN at 160, i can conclude that its not following this map for the boost

This tune is good, turbo is high but this is normal with this engine.
Did you try it?

I did, than i went back to the previous one i had, The File you provided has 30 Degree timing advance, with RON98 i get 6 degrees of timing retard, i feel the file has potential, but as is i cant use it, i mean i can, but i dont want to, i would rather have 0 Retard, also Injector duty cycle goes to 125% so if for some reason my ecu needs to inject fuel to keep temps down it cant ... so pistons will melt. the file is losing power somewhere, i lowered the timing advance from the 30 degree max to 24, the 0.77 lambda to 0.82, and lowered the turbo from 21 psi to 19, the log i did with the file you sent me gave me 219hp, after my changes i logged 232hp, afr is a lot better, injector duty cycle under 100%, max of 0.75 degree retard on 1 cilinder only, while yours was retarding in all of them, so i chose not to use it, going back to stage 0, i habe a 4 bar FPR in my garage waiting to be installed, than i get extra 15% fuel out of it, i want to keep the turbo under 18 psi tough, and play with the timing instead, perhaps 16 psi even, as i have the stock intercooler and dont want my intake temps to get too hot

I checked again but can't agree, the tune was already being used without any problems for several years so something is different with your car. It was dyno'd at 230hp so something is different with your setup.

Im sorry for the late response, i have been sick these past fews days, im willing to get to the bottom of this and make this work, What car have you been running this on ? Also what Fuel ? Any Mods ?

In my case is a Golf Mk4 2002, 1.8t 20V R4 AUM Engine 9.5:1 Compression ratio, 062 Block, 317cc injectors with 3 Bar FPR, Drive by wire, VVT, 70mm MAF, K03S turbo and i always use Shell V-power 98Ron with 5% ethanol

95ron 10% fuel is used, this might cause a little change but who knows.
Your injectors are slightly bigger than factory so this might be another thing.
