Title: Torque limiter
Post by: Jim_Coupe on October 13, 2015, 01:22:32 AM
Just to have it confirmed. As i have understand its the throttle valve that is limiting air from passing through to keep down the torque? Im not suprised if there is more stuff thats in the way aswell.

To raise the torque limit or request i must know where i am today, therefore i suspect i need to log calculated torque and requested torque right? ???

Log intervention variables.  Have you changed IRL and IOP?

The throttle plate has nothing to do with torque intervention.

Thanks Adam.  I think i have to take a look at IRL and IOP i havent touched them. It feels almost as if the turbo build boost earlier than i can feel so to say. Boost is higher pre-throttle than in the plenum after throttle maybe. Maybe Throttle cut. The system is leak tested.

Why do i need this Torque monitoring anyway? Why cant i just disable it via KFMIZUOF and go all in :)  If the gearbox breaks down its to weak and need to be reinforced anyway? Rods are Forged h-beams and cracnk is forged.. Whats the problem :) If im wrong slap me in the face.

IVe also read that some have just increased IOP 25% in some areas and IRL 10% in corresponding areas. Is this a correct path to raise torque?

First and foremost, get some logs up.  Obviously if you've got rods you're running a larger turbo. 

What hardware have you changed, and what maps have you changed to support it?  Bigger MAF, injectors, turbo, wastegate, what?

We need logs to help, and you've posted a question that doesn't even make Engrish and then you say "I'll just disable TM".

If you're getting throttle-cut, you've mapped it wrong.  So, tell us what you've changed, and post some quality ME7Logger Logs!

It had been wise to first of all clearly explain in OP that this is regarding a NA=>FI conversion.  ::)
And although rules of physics are the same in a NA and FI engine the setup of Motronic is NOT.
I would say that questions regarding NA=>FI does not fit well in N00b questions. And since you are new at this and the questions asked would have been best placed in n00b if they was regarding eg 1.8t or 2.7t you have nowhere to put these questions as of today.  ;)

Learn tuning motronic on a FI 1.8t or 2.7t before trying to do a turbo conversion of a NA engine.
Then when you know more about general Motronic tuning you can ask relevant questions in tuning forum about NA=>FI conversions and forget about n00b forum.  :)

Aw, sake!  I keep forgetting that this is the most backwards thing ever and that I've already told him to just get PRJ to apply his patch to control boost because this isn't going to work.

This is why you're getting throttle cut - because the ECU is seeing boost and has literally no idea what to do with it.

Well it still needs a lot of work and learning I. prj has PID code to control a n75 on NA ecu but I don't think his code do anything to help ecu when there is more load than expected.

Thanks for Answer..  But it didnt quite really answered my question about torque torque limit. Just answer my question about KFMIOP and KFMIRL that would be fine. If the case is that I get a throttle cut is just a thought for now.. but it can also be the nature of this engine, poor turbo and so on.

-adam im soon starting to believe you are promoting -PRJ so much you have some deal to make ppl buy stuff from him or something.. All this PJR PRJ.. Let me tell you something! Answer my questions not promoting PRJ all the time man.. I KNOW this ECU has a diffrent algo for NA engines.. Im learning my self here man, do you have a problem with that im stumbling forward trying and trying to learn this?
And by the way. Do not forget that couple moths ago i talked directly to PRJ and he is NOT intressted to help me out due to vast distance between us.. So what do I do.. what do I do when prj say no no ????? So can you please stop interfere in my threads, that would be really kind of you. Or we could have a seriously discussion about this on skype if you really want details about my build. and BTW.. Im close to wriring my own N75 boost control via ECU the witing is done and output has a boost table. But ill keep that for myself for now.

I had one question and it was about torque limiter. Thank god this awsome forum have already discussed this alot in this thread.. http://nefariousmotorsports.com/forum/index.php?action=printpage;topic=970.0
 

Thanks wannabee900 thats exactly my conclusion for now. need to learn more of this.

I've never spoken to PRJ in my entire life, but after reading all his answers on here tells me all I need to know.

I myself put up a thread about boosting an R32 and he chimed in and said that if I wanted serious help to PM and he would create a file for me.  For money, obviously, but still, he was more than helpful.

I'm not promoting him or his business, I don't even know what part of the world he's from. 

If the case is that I get a throttle cut is just a thought for now.. but it can also be the nature of this engine, poor turbo and so on.

Not only that, you've just commented saying you're not even sure on the quality of the hardware side yourself, and yet you're still asking us for help, and you've STILL not posted any logs.

Im close to wriring my own N75 boost control via ECU the witing is done and output has a boost table. But ill keep that for myself for now.

Why don't you post up what you've done, so some of the experienced members can help you/tell you if what you're doing is right.

If you really want help: document your thought process; what you're changing; logs; more thought process; logs.

Good luck, bud.

Again, this is the wrong project to learn ME7 on.

Learning ME7 on a R32 turbo project:

Yes PRJ :)  and it feels really great.. So now when I have all your attention.. please answer the following question: Can KFMIOP and KFMIRL cause throttleplate cut? 

I was out logging with VAG-COM (block 120) yesterday. But could´nt find any good parameter that show actual throttle plate angel Vs  pedal angle. still locking for a better way to log those parameters.





Title: Re: Torque limiter
Post by: prj on October 16, 2015, 09:42:45 AM
Yes, sure. Like about a million other different things, some of which are unsolvable without modifying the program code when going from NA -> Turbo on stock ECU.


Title: Re: Torque limiter
Post by: adam- on October 16, 2015, 02:04:48 PM
Why are you attempting to log with vag-com?


Title: Re: Torque limiter
Post by: wannabee900 on October 16, 2015, 02:31:04 PM
I think that without modification ME7logger don't work with Jims R32 ecu.

He'll be better getting some of the def files off here and defining the 711 in full to learn it first, he'll not have modded the map structures/axis to cope with fi yet, let alone should be modding the data within them! The ST10's are difficult to define as a noob with the resources on here but not impossible.

Can't remember what the na/fi files I used were in the pic, but I took them ages ago as an example to show the axis/value differences a while back.

Here's an early 711 map data file I did, may need to check if auto-fill changed any factors though on this one. It's done in Libre/open Office which is free if your file reader doesn't work.

It works just fine.
However, you need to create the .ecu file yourself.

Good to know.
.ecu is no problem :D but is not a 1minute job

I tried create the ECU file.. but i gave up after some time after feeling like "The Tourettes guy". https://www.youtube.com/watch?v=2RKfz_Q0Mek (https://www.youtube.com/watch?v=2RKfz_Q0Mek)


 I have to use what i can now. So far everything works good. But if im gonna get this machine fine tuned i need something like Me7 logger to get a better process picture.

I think i have to give it a bit more in IRL and IOP it feels like turbo wants to live but the throttle wont let it.. And it sucks that i cant logg this correctly
