Please rate my tuning...

[Jan1980]

I made a tuning file for 2002?Golf 4 1.9 TDI with 130HP. Please take a look to the file ! Is it safe ? How much horsepower gain do you think ?

Thank you !!!

With this map you kill a car in seconds!
Don't write this s**t!

[Jan1980]

It is for learning. Why kill the car in seconds ?? How can you rate exactly in 6 minutes ? Please write why it would kill a car.. I want to learn.. THX

[mateusz1611]

The long road ahead of You....
File is terrible

[Jan1980]

Why ? :D Please don?t write just, that it isn?t good... I want to learn why..:D

[Babos]

Why ? :D Please don?t write just, that it isn?t good... I want to learn why..:D


If you want to learn write dump and drive and then to do other corrections and check how car now work! teory is good but practic work better!
And about tune you can use your dump dont worry he not perfec but is ok

[Jan1980]

Babos, you are a good man. I remember, we wrote on PM before a few weeks. Thank you for your answer ! To the other guys, WHY do you write, that it is shit ???? I only changed some tables with a small range of percentage. I am working with engines since 20 years, i know the sense of the tables and how an engine works but tuning is new for me. I want to learn, which tables can be changed by a better way. You know what i mean ?
Never would be damaged anything with this dump ! WHY DO YOU WRITE, THAT IT IS SHIT ????

[Act Tuning]

You can start with that turbo pressure 2.7 BAR !!! 2nd run piston is going thru the front glass, with some more spices you did,
alought you limiter not coortly, and why you tuch duty cycle ?? did you replace bigger turbo ??

[konq100]

Read and learn edc15 tuning guide mate! Do it for the health of your car!

[Jan1980]

But there was original 2620 mbar in the value, now 2700 mbar. Just 80 mbar difference on the max boost value. 2700 mbar absolute pressure, so 1700 mbar pressure. Or which tables do you mean ? Turbo map or Turbo limiter map ?

[GabrielMga]

Too much torque early. It is not a good idea

[Act Tuning]

Examaple : 2247rpmx50 ori: 2350 and you put 2702, you dont increase all area by 350mbar turbo pressure on this car,

[Jan1980]

Ok, that?s what i want to hear... The reason for my shit.. :D
I understand, too much pressure in low range. What about fueling ? Is fueling ok ? Have i just to make changes on turbo tables ?

THX mates !

[konq100]

Too much torque in low revs, but anyway you are limited to 60mg/str by MAF and MAP limiters.
Duration not touched, SOI, Smoke, Turbo, N75... No good mate.

THX mates !

About fueling, you dont increase it by % as same raw diff numbers, you need to know howto calculte the fuel to inject by know how much air you let in to the engine, and put in manually each raw from low to high, read alot about fueling you cant just increase the fuel and pray that you on the correct AFR to gain max torque.

[Jan1980]

I made a new version with other turbo map. Can you take a look again ? About fueling, i made now an excel table to calculate the air fuel ration.. :-)

In this version, just turbo map changed...

u kill nothing in seconds :-)

you can do your maps better boost 1,7 is ok for this turbo no problem i do 1,65 make your boost limiter better to low for 1,7

dw max 70mg

same torque

same smoke limit

here a file

[Jan1980]

Thank you for the file !!! I compared in Winols with original file. Now, i think, i know my "tuning-troubles".. :-)
I will make another file with learnt things tomorrow and post it here. Thank you again, mates !

If you say you boost 1.65 that mean 2650mbar, on max 70mg of fuel you will be seat on Stoic 24.88 that is very bad and lean, you need to aim Stoic 17,that mean to achive max torque you need to adjust boost to 2540mbar in 70mg fuel to max the power,

[Caniho]

Hello, I have a Audo a3 asz is the same as yours, I take 72mg injection to 2550 turbo, the SOI maps adjusted for the injection and the car is perfect, you should climb the axes of turbo and duration for injection new.

Sorry for my bad English, googletranstator use.

[Jan1980]

@act tuning: I have seen your calculation. You calculated 1650mbar divided by 70mg of fuel = afr 24.88 ??!! Right ? Can you divide pressure by milligrams to get stoic ?! I thought i have to calculate air mass / fuel to get the air fuel ratio ?! Not the pressure, the mass.. Just a question.

I thought the completely mass on intake is = incoming air on MAF multiplied with turbo pressure ??!!

Other question. I know for petrol

afr 14.7:1 = Lambda1 = best combustion for fuel
afr 12.8:1 = air fuel ratio for acceleration
afr 16,5:1 = lean mode, highway mode
afr 8-10:1 =cold start

How are the best ratios for diesel ?

I think 14.7 is too rich. I think to know, 17:1 is the best ration for combustion. I made an excel calculation and i have seen there are rations between 16 and 22 in different maps.

THX mates

[Caniho]

In diesel engines afr 17: 1, with afr 16: 1 is some smoke, to calculate the AFR can use the map MAF if you do not want to complicate, if you feel like you can do so complicate:

1900/4 = 475 (volume of a cylinder)
475x2.65 (absolute pressure in bar) = 1258.75
1258,75x 0.9 (efficiency, temperature) = 1132.875

With 1132.875 base you can calculate the injection with the afr you want.

(google translator)

[Jan1980]

Ok Caniho, i understand. But with this calculation, you are working with volume, not with mass. The mass can be different. Colder air has a higher density. And you are calculating with absolute pressure 2650 mbar, but in cylinder is not a vacuum, there is (theoretically) athmosphaeric pressure. So, i think it is not the right way to calculate with absolute pressure. Or i am thinking the false way ? Please correct me if i am wrong...

[Caniho]

This calculation is to calculate the mass of air that enters the cylinder with a turbo pressure of 1.65 bar (2.65 bar absolute) and multiplied by 0.9 is for this reason, air temperature, efficiency the engine intake, but as I say the easiest thing is that you calculate the afr with MAF and this will be the limiting you to not take smoke, you just have to do good maps duration for the MAF limit you correctly, making well you can get more or less smokeless 70mg, 72mg but I have seen some smoke.

[czerkam]

Jan1980 it's hard to explain just years of years of Tunners experience that is covered with houndreds of road testings, however Caniho's calculations are "the best practice" to provide AFR in level of 17:1. That's why 1132,8 / 17 should be max value of mg/str for your engine (~65mg/str) for not seeing smoke behind your car. From my oppinion I suggest you to start once again and just increse values a little bit and flash to the car and check parameters.

Second issue is that it you want to prepare your remap as so called "safe one, for not damaging your car to fast" or you want to build up "litte monster with max performance, smoke and 1/4 mile killer". In my oppinion you mods are to "heavy" for begining.
Especially Driver wish that is far more above 70mg/str. Stay with 70mg/str for 100%. The same with Torque map. To much Nm from bottom of rpm's. I suggest you to use max 60mg/str. Also if you increase DW and Torq >70mg/str but smoke map has max. 63,5mg/str. There is no consequence in combining all 3 maps togerther. Duretion map are quite ok. Regarding Boost Map std 2.35 can be safely extended to 2.45 which is safe for the turbo. Ofcourse you can do more, but for the beggining mod's i believe it's not necessary and not safe. It doesn't mean ofcourse that tomorrow you'll be collecting from the street loose parts of your car but however you should start with little steps.

[Jan1980]

Again... Please rate my tune !

Today i made an excel table to calculate smoke limiter in stocheometric values. x=airmass in gramm per stroke divided by fuel mass in gramm. I changed values percentage and doublechecked new values in my excel. With my smoke limiter in start point, i changed values in driver wish and torque limiter. Then, i took a look to the turbo pressure. I want to let it under 2600 but with other response point in rpm middle range. Please take a look...

[Pyromaniak]

good for this is make a sure how much presure can presure sensor do it. if waste a N75 valve and turbo goes max, the ecu not make limb mode for more presure... Best way ist boost meter on board, to safe your turbo. Limp mode goes if presure ist 500 0r 300 mbar up or down over the value for turbo reguest...

[voltechcar]

hmm, too much but maps who you modify to 80% its ok. Write to me to pm, I check your file and write what is good or what you must change. My first tune is killer( this is words my friend who is teach me ) I see package maps which Italian tuners upload in server, your file relative to their its weak :chuncky:

Regards

[Jan1980]

Bump... To tuners, please write about my mistakes.. :-)

[bobolin4o]

There is nothing to say more... simply - you don't know what you doing.
The IQ will never go more then 60mg.
Read again previous posts...

[Jan1980]

Ok, thank you. I will take a look again.
