hi friend.i bye this car , but to tune this ecu is not symply for me.
this is me7.5 ecu.
i try some and some maps but  the result is not good.
i have k04 and mainfolw from s3 225hp, 370cc injector from tt 225,ic 17l,popoff bonalume,r32 maf,8 bar gasoline pomp,bcm air filter,70mm exaust flow.

with this turbo i like to do 270hp. but max i do now is 220hp of 1.3b presure to rpm.
i post my maps , if anyone can see wen im wrong.thanks at all.

Norhing opinion? Thanks

post me7logger files, no vcds, no maps, just logs

what other way to do logger?

Hi there,
Visual ME7Logger is the way to go for logging.It's a really great tool and free.

All the best
O.T.

I dont have it. Whic tool need to bye?

this my dyno today. Whit 1.2 bar at limiter and 11.4 afr.
But torque is fast down and have holle on hp.

Dude. There are stickies all over the place.

Stop wasting everybody's time.

Hi there,
You don't need to bye anything,it's free.

Also spend lots of time reading the noob section and noob guides together with the tuning wiki. It's the only way..................

All the very best
O.T.

At a guess;

"popoff bonalume" will cause you problems, R32 MAF is same top end flow as 225hp 20vt, or are you using mk5 R32?, injectors are 386cc or something aren't they?...... Dump the BOV, flash on 225hp map (MPPS V13+ should do it) and read the tune threads on here = sorted!

It always astounds me that people think venting metered air is a good idea.

Just as a note, Bonalume also makes/made a recirculating "popoff". Had one before I bought a forge :)

I also see that way too often, where I live people love putting a "splitter" valve on their 1.8t's thinking it'll be fine.
Tried venting mine to atmosphere once just for shits and giggles, engine choked itself on fuel first time I let off.

But one thing I can't understand is that I have a friend with a Nissan S13 CA18DET and it doesn't give a shit if you vent to atmosphere, and it also uses a MAF?

Ok.  I have maf of golf 4 r32,injector tt 225hp.
Maybe bonolume is not tje best way but dont belive , bonalume make down my torque.
I read and write whit ory galletto.
Haw much hp can i do whith this turbo? Need to do somthing on maps?

With that setup, a decent intercooler and 95+ octane fuel you should be able to make 260bhp with a decent tune.

But as you have been asked this whole thread, post some .csv logs from me7logger. Until then everything is just guessing.

Thanks.my vag cable is cooming today.
What need to log?

hi. this is my logs.

There are many variables missing in your log.
there is no nmot in the log, no iginition retard, no lambda, throttleplate angle and so on

the only moment where you hit the pedal 100% and maf is showing numbers you can see that
injector time is 20ms which is maxed out = lean = melted pistons

Hi there,
I think I might remember feeling a bit like you do with this stuff...... ( I still don't feel much different either... )

This is a link to my thread.You might find it helpful with getting started on all this.
http://nefariousmotorsports.com/forum/index.php?topic=11027.msg93212#msg93212

I've only just started this myself and I remember,it is absolutely horrible getting started.But this group of guy's will walk you through it all.If you look at that link you will see.I had to be taken through it bit at a time in baby steps.

You have to take this very,very slowly and do lots and lots of logging until you feel confident with the logger.

All the very best
O.T.

Last update of my car. My k04 turbo bye s3 225hp is dead.
I bye other turbo from usa, derivated k04 from fsi maybe.
Is plug and play. My firts turbo max boost i do is 1.5 bar.
Now with  new turbo all map i do all maps i write the car do 3.5 bar and 1 bar at limiter.
Big problem. N75 work ok, map is ok, vacume tube is ok. I cant comand n75 bye maps.
Evry time is 3,5 bar picco and 1 bar at limiter.
I put mbc boost, 1.5 bar costant at limiter.
But have only 240hp. Afr 11.7.  Any idea?

No. Just no.

Please avoid that garbage.

sorry master, can expland please??

You don't need an MBC, the N75 gives you all the control you'll ever need.

i cant control n75 , write new map with only turbo limiter, have same problem , pressure go up at 3.5bar and 1 bar at limiter.
never touch KFLDIMX and KFLDRL . i tried to tower the KFLDRL but same result.

A log would be more useful.

What exactly need to log to solve n75 problem?

Log everything you would normally log using ME7Logger.

ok . i log retard  and timing .

More bits.  You can log loooooads of variables!

Please, log more.

https://s4wiki.com/wiki/Tuning#Logging_utilities

need to log all list?? i dont understand sorry. cant tell if timing is ok?? ore need all parametres ??

Yes, log everything. It makes finding problems easier.

This thread is a waste of everyones time and this italian guy will never ever learn the right way.

if you expland i understan if you tell only log log log i dont understand what.
thanks for  you time. thread closed.
thanks

Sorry bro, its not our job to explain you verything.
You didnt even try to log the posted list of variables with the tool we recommended.

sad

Nyet, he might take "log everything" literally.

now i stop to test on my car, me7 have much variable and i dont have time to log al one bye one, dont have dyno to test evry day,have only city street to test and you now is much dangerous for other peaple and police kill me  ;D ;D .
need to contact eurodyne ore somthing , hope help .
this is my last log . i log all on list,manual boost.

Why are you requesting 22 psi when your turbo can only manage 17?

Or perhaps you are expecting 22? You say manual boost. Do you mean MBC? Ditch it.

I hope you aren't venting to atmo.

Better log from 2000 to redline next time.
Log when engine is warm, at ~90 degree. 
Your logs from 3 to 5,5k are not that useful.
You have to put your pedal to the metal  ::)

what is your lamfa like? afr desired is 0,77?

yes , manual boost is MBC .my afr on car is 10.5, is so much rich. i dont touch dhe lamfa map, is original and original have value 1, 0.9 at limiter.
To learn ,like afr 11.5 need only to go up with turbo pressure and adjust timing , 1.5 bar is ok. but my problem is, eurodyne ore other peaple , tell with 1.3 boost do 300 320hp. with last map at same pressure i do only 240hp.if i go up with pressure , i try 1.5bar , my afr go to 11,2 but hp is only 243hp,and need to understand what is the problem.my maf work good, load is ok, timing are in the standard. i dont now

You need a much better understanding of the ME7 ecu work and all its strategies
You can't just knock around some maps and expect to pull max rated power out of the turbo and engine.

It's a long, tedious and repetitive task to really fine-tune an engine so it performs at its best.
It's not just a six pack and a hour job.

spagettituning  ::)

You can log more than one variable at a time.

Lose the MBC, lose the blow-off, learn ME7 properly and you'll have a great time.

1.5 bar with 0.9 lambda?! You're hitting EGT and that's why it's dumping.

sorry aef , you are normal ore stupid peaple??? what is spaghetti tuning?? if you dontlike dont  write on this section.
i dont like to offend on forum but you write 2 post and in this 2 post you provoked me. FORUM IS FOR ALL PEAPLE. ITALIAN ORE CINE ORE AFRICA ORE USA ORE ALL.if is only for stupid peaple write please. hope you undestand me. thanks for you help.

Look here pal.
We're not here to shit on your parade.
We are willing to help, but since you won't or can't
supply us with the information or data we need to help you.
Then we can't help you.

We are in no way obligated to help you, we do it out of free will
and use our own free time to do so.

And "yelling" at people because the won't help you,
because they can't with the little data they have
isn't constructive or will help further your cause in any way.

I do not expect anything. I ask for help, do not yell at anyone. But if I feel offended I answer as well. You were not obliged to help me, I never did. Thank you anyway for your help and apologize for the lost your time.

Let's get back on topic, since you ignored the single most important piece of advice here:


All of the above.

My personal experience would advise you to lower boost, and add timing instead.
And get your fuel sorted before you begin to boost the living hell out of it.

Also if you are basing your EGT on internal EGT model, then it will be off if you are using a TFSI turbo.
If you have a EGT sensor, See what modeled temperatures are in downpipe or before cat instead of manifold, and make LAMBTS use that temperature.

i have franken turbo f23 kit . if i remove MBC and connect n75 my boost joke, i have picco 3bar ore more turbo pressure, KFLDIMX and KFLDRL are original . i try to decrease the KFLDRL but same result , big picco boost. cant handle the KFLDRL. and i thought for mbc solution ,now have 1.3bar boost. 880 grad egr . 10,5 plx afr .
i go up with pressure , max i try is 1.5bar, i ajust timing , LAMFA and KFLBTS. plx afr is 11.2 but nothing HP more that 243.
car have beautiful torque 410nm , 243hp but after 4700 rpm all finished .

Its about the way you tune.
You are a commercial tuner and dont even know how to log?
Do it again with WOT in the whole range and remove the mbc like adam recommended.

take your time and do it the right way.

And you didn't bother to log to figure out why? If you can't get anything working without an MBC, why bother tuning at all?

Stock DIMX and DRL will never work with that turbo.
And ME7 doesn't like when you remove the N75 from the boost control loop.

I suggest you take a look at the LDRPID tool that was created not long ago,
that would definitely help you control the boost with the N75.
But you will need to be able to log with me7logger.

Hell, just use RAPP to calibrate it to get you in the ballpark for an estimated DC and properly controlled fuelling.

i did several test. now i pute the bcm , all this time i do test to manage picco boost . but without sucess . all my atention is for KFLDRL and KFLDIMX . i try to incres and decres value but same problem . exist other map for n75 manage??

Why did you just post a bmp enclosed in a rar? Post a log or nobody is going to be able to help you.

LDRPID has many setting.
But it is a clusterfuck.

Read the boost PID section on s4wiki, that'll get you started.

ok. now is the 22.30pm . tomorow i restor all n75, tune and send log. thank you.

This is not even remotely how you tune the PID btw :)

hi. today i test with n75. car wen go up of rpm go bad. same 3.0bar picco pressure. max i test is at 5000rpm becouse I was afraid to damage engine , it seemed that knocked. with that pressure i tell is normal. possible my n75 is broken? can i post my mod file??

You are not interestend in good log  :D

Why is there a bump in rpm
why are you starting above 3000rpm
why dont you push the pedal all the way in

The line of your maf readings is strange and your fueling is rich.
Would reduce timing and fix fuel and boost first.

What turbo is this in detail?

i test car on motorway,  and are other peple, im insert on 3 gear and log for this rpm. my problem is the turbo managment, the turbo pressure with n75 dont match on what i have on maps. if i pute the full pedatl on 4 maps , with 3bar of pressure i damage engine. i like picco 1.5 and 1.3 costant. i cant do that. my turbo is franken turbo f23 kit, il hybrid k04 turbo , maybe from tfsi ,im not sure. 

Have you calibrated the R32 maf and the injectors?
Attach current tune and ori.

yes i do maf calibration. about me i do good tune file. im gelos for this work  ;D .
im almos sure this is meccanic problem. let me now please.

You havent done this file on your own, have you?

There are lots of small useless changes.

Injectors: only krkte, no tvub, temin and so on
Maf: which r32 in detail? whole maf or only sensor?
There is kfldrapp changed but CWMDAPP is not?!

Would start from original file and recommend to log on the night time when motorway is empty.

i do all this file. the tvub i dont now to change, is voltage? CWMDAPP  is for wat? need to put 8??
my maf is r32 golf 4 , all maf i change, sensor and housing.
about you with this map my n75 is correctly?? possible to do 3.0bar??

dude.  doood......

You need to just back up and start over.  You are in over your head at this point.   You obviously have not attempted to learn the basics.  I don't have anything constructive to add here, other than the fact that ultra-noobs seem to have a better handle on remapping than you do.

ffs.....

I really hope it's your own car you're doing this to.

You need to read A LOT more, before attempting what you are doing.
Read all you can find about PID controllers and calibration of them.
And then read all about LDRPID module.
That would make you able to calibrate a different turbo to the ECU.

And please read until you understand the fundamentals of fuelling on this ECU.

ok i restart to begining. thanks at all.

Personally, use the PID linerisation method and just leave it without a PID.  Simpler to get your head around and will stop this 3 bar shit.

newss . ;D . for all master . i finde problem on my car. one of dontreturn valve , to n75 at throttle is broken and dont pas vacum air. i change it and all ok. i can manage pressure as i like.
thanks at all for this constructive chatting .  ;)

Let me get this right, you have the N75 feed line hooked up at throttle/intake manifold?
And you have a check valve in that line, oriented so that it only sees boost not vacuum?

That would prevent boost from escaping the manifold->N75->wastegate loop
keeping the wastegate open unless the N75 is venting. In theory.

Anyway, glad to hear you got it sorted :)

yes. im happy fot solve. but I'm glad that the problem is not from my map .
this is a gratification  ;D ;D

post logs  ;D

my first problem is 3 bar of pressure . now i fix boost at 1.3 . and now log timing , fuel and egt.
wen i dyne all i post log. ;D
