Car:
VW GOLF 5
1,9 TDI PD
90HP
2008 YEAR

THIS ITS NOT MY TUNE I BOUGHT IT FROM A CHIPTUNER IN MY COUNTRY

From my experience if you have car with 90hp you can go sleep while driving with full thorttle so i decide to tune my car....
I found some chip tuner he was kinda nice to me and i decide he tune my car... He needed like 2hours to do that work, it was my first experience doing any tune on my car and i was patient while he its modifing my car... He uploaded modified file to my car and we went for test drive... The car was really strong and i thought its really good tune and i pay the guy and drive home...

After few days, i noticed on low rpm around 1500rpm to 2000rpm on full throttle car spikes alot, you car hear clearly while driving in the tunnels, i was like maybe its nothing and i didnt pay any attention on that ( i didnt have a clue what spikes mean in that time )

So i went for proffesional tuners in my country ( they are really expensive in my country ) and i ask them if they can give me some advice how its done tuning... He wasnt to much happy about this tune and he amidietly show me remapped files and how he remapped them. When i saw that i wasnt happy too when i saw what he did for that money....
I decide to show you guys my story of chiptuning my car and why i decide to start tune my cars and other people cars, beacuse they are so much people they think they now everything and they not do a good work and rip you of your money...

So i pay: 150€ ( he give me a discount for first tune - without dyno test )
Proffesionl tuner: 300€ ( + he put car on dyno test )

SO MY ADVICE NEWER GO TO NOT HIGH POPULATED TUNERS IN YOUR COUNTERY, BEACUSE MAYBE HE DONT EVEN KNOW WHAT HE ITS DOING!

I dont have a original file from my car, but i found on some forums ( same ECU number ) and i tested on WinOls and this two maps go together so you can see the difference betwens this map, and leave a comment belowe what did you think about this tune...
Did he forgot to change any map they need to be changed?


IN ZIP FILE ORIGINAL + TUNED FILE

The file is not bad, but if its made by a pro tuner then he can start looking for a other job.

This are my findings:
EGR is still active - tuned cars need only clean air to make more power.
Injection duration maps are tuned with added crank degrees - the car will smoke a bit. The map is decalibrated.
The torque limiter is tuned from 551RPM :D Do you realy need more power when the engine is idling?
He tuned the smoke limiter MAF but he forgot about smoke limiter MAP. Your IQ is limited to lower spec.
SOI maps are ORI. They make difference in power and fuel consumption.
Boost maps are tuned in % not with knowledge.
N75 maps are ORI. The car will NOT make requested boost when you do data logs.
Hot start maps are ORI - when the engine will have big mileage it will expirience difficulties when starting hot.

Lucky for you that you paid only 150 euros. You got what you have paid for. Next time go to a real professional.

Yea i know next time pay more and you will get proffesional tuning, but its was my first tuning and i didnt wanna pay so much more money beacuse i was thinking its the same tuning but only bigger companys wanna take more money from us

So can anybody help me identify all maps so i can learn from it....

I dont recognise this maps but they were tuned and i wanna know how every map its called so i can see what he tune:

( if i miss any map please help me find it, i wanna remapp this car as fast it possible )


When i saw what he did with a remap i was shocking....
car need more power at 551rpm ( noob tuner )
turbo map ( boosted almost all turbo map by 10% ( who need boost at 1000rpm by increesed 10% )
turbo limiter map ( again same story, almost all map increesed by 6% )
Maybe i miss some map i didnt pay attention but this car need to be remapped as soon its possible...
I will really appreciate if you help me indentify maps and with together work try to fix it

Funny story,
I called a tuner and ask him to fix my maps, and he anwser me he dont know how to do it, but he have pro tuners in germany they tuned my car and all other cars he did it...So you have a tuning company and you dont even know what its ECU

So i decided to try by my own but i am not expirerianced in EDC16 bosch so i almost reduce every map i saw he did wrong...

My fixing map:
Drivers Wish
Smoke limiter maf (calibration) - i almost reduced all none usefull % in my map and i fix it with my own ( lower % )
Smoke limiter map - i only get some more % ( nothing special )
Torque Limiter - fixed from 551 to 1000rpm to original stats
N75 map - ( my car spikes so much you can hear it with windows closed ) --> so i reduced last three columns ( i hope i didnt improve more spikes that was before beacuse the EDC16 its much harder )
Boost Limiter: I improve last 2 columns to get higher limiter than its turbo map
Turbo map: I did some changes with lower RPM and i choose some columns and get them to original
SOI - are still original ( dont have clue what to do with them )
Hot Start - can anybody can help me finding map and help me with some pictures or telling me what i should do
EGR - i use ECUsafe to help me turn off egr but i dont know if ECUsafe did that work
Speed Limiter - i remove speed limiter

Maybe i forgot some map to change so guys help me remaind what map i forgot to change or what map need more remaping to prevent spiking,smoking

Can anybody tell me how much its my SVBL ( i wanna check how much its limit for my turbine )
I know every map its on % ( percentage ), i didnt calculate but i almost reducing everything so i hope i didnt do the worst job then its now tuner tuning map

Are you sure that is your car?
Are you sure your engine is 90HP?Ori file is for 105HP.
Tip: never buy a mod file , tuner will sell a crap, he thinks he will lose some customers of its ,he think you want to multiply the file and sell it at a price of nothing.
Zaslužiti dovolj denarja, in če ne, potem proste

SOI: 1DAB38 + 1DAD38
Its there any more SOI maps they need to be changed?
Can you help me abit about SOI maps how to tune them... I know i need to increese numbers to injectors be longer opened and i can get more Mg/stroke more fuel inside my valves...Can you give me a little tip how to tune them?
I think i need to increese lat 2-3 columns at 1500rpm and higher so i can get more fuel?
How you can calculate how much you need increese more SOI?


Can somebody tell me what its this map:
1EB3D2 + 1EB61A
and
1EB4CE + 1EB716
I dont know what they are but tuner tuned them and i dont know what are these maps
If somebody can tell me i will take a look and think about this maps how they need to be tuned

I am working now with Original map all by my own. I wanna start fresh no fixing maps after tuner tuned them and forget alot. I wanna a much beatter tune and power then its my previous files....
Pro tuner tune in my country this type car for really good power:
Hp: 132hp
Nm: 290Nm

I wanna get close to this tuning :)

And my last question, my SVBL its limiting 2350mBar so can i push my turbo to my max SVBL ( like highest in my turbo map will be 2350mBar, is it still safe or turbo will have any troubles?
My car its in really good shape only 75.000 KM driven, i was never have any clutch or turbo problem, or any other problems with my car

A few hints for SOI:

at high RPM, the piston moves much more quickly than at low RPM. So, if you inject the same quantity of fuel at the same SOI at different RPM, if everything's perfect at low RPM, then at high RPM you will be too late and get lots of smoke/inefficient combustion.

This is because the piston is already moving away from the expanding combustion gases, since the injector takes the same amount of time to inject the same mg/stroke, but the crankshaft is just turning more quickly.

So to compensate for this, at high RPM you could try to advance SOI 1-2 degrees crankshaft. VW has done this already, if you look at the SOI tables, but you can squeeze out a little extra.

Also, if you are already at the smoke limit or smoking with unchanged SOI, you could burn the same IQ but more cleanly by advancing SOI.

It's not really meant to inject more fuel - but to adjust when fuel injection starts (SOI = Start Of Injection!).

Another thing: when you change to larger injectors, you also need to advance SOI - because the larger injectors mean slower pressure buildup. Why? The larger nozzle openings mean less pressure buildup - think of a garden hose with water running through it that you press together with your fingers and then try to figure it out. Variable pressure, from almost nothing to hardly any water going through - you'll get it.

The key to adjusting things is understanding them first, or trying to as well as you can. This is friendly advice from one beginner (me) to another ;)

Regards

Thx for help i read alot about the SOI, but its really hard to understand it, they are really complicated

I made a test file modified SOI map but i am not sure if its good?
Can somebody check and give me a replay

Hi,

haven't looked at your files, but forgot something - changing SOI also changes when the pre-injection occurs, obviously - it still starts at the same pressure, but since the injection process is started earlier, you reach this pressure earlier, as well.

This is important, because the pre-injection determines when the start of combustion happens - so if you advance SOI too far, combustion will start while the crankshaft is about horizontal, which will make the piston want to move BACKwards (since there is an expanding flame front pushing it down) and your piston con rods will have to take a huge amount of force, which can bend/break them.

Similar things happen on gasoline engines when the fuel is bad and the map is for 102 octane, for example - you get "knocking" and can kill the con-rods (knock regulation only goes so far). This also happens because the fuel spontaneously ignites on its own without being ignited by the spark plug and pushes the piston backwards against the conrods.

But back to Diesels :)

So that's why I said you can squeeze out a little extra - at WOT, VW has already used pretty ideal SOI for the IQ they inject in the stock file. If you increase fueling, you usually can still advance SOI a little more - but not too far ;)

Somewhere in tuning forums you can find the max safe SOI for your engine type (in crankshaft degrees), I don't know them. It's never good to go to the limit right away, start at a safe distance and work towards it.

Regards

OK so i read something about SOI remapping, correct me if i do any mistake

SOI:factor: 0,023437
Output: Degrees BTDC

Duration Map: factor: 0,023437
Output: Degrees how long the injector stays open

When are you modifing Duration map ( calibration map ), so your map need to be on degrees
After moded duration map you got your finally degrees and you open SOI and calculate how much extra degrees need to be changed to get SOI working good, but max modifing SOI its like 2-3 degrees max.
So can you do like 2 degrees on low rpms, on a higher rpm 3 degrees

Does any map missing there need to be changed too while moding SOI
