I'd modify the axis if it were me.  There's no resolution under higher loads..

It's a possibility, but I don't know if that axis is shared with any other map... Is it?

Anyway, are these lambda values safe enough from your point of view? I put a minimum of .82 because I think revo does the same in its stage1... is my KFLBTS rich enough to not cause damage in components like valves, the turbine, the manifold... what do you guys think?


Ps: By the moment, I'm not requesting higer loads than the maximum of that axis, 150.

For stage 1, yeah, I'd say that's plenty rich!

Provided you don't go above loads much higher than 150 I'd say you're good to go! Smiley

Well, actually It wasn't hahaha

I gained 8g/s since last remap, but I'm getting 4.5ยบ of ignition timing retardation between 5000-6000rpm @WOT in cylinder 3, and 1.5 in other cylinders
It might be better to enlarge the 0.82 lambda area... I think It'd be perfect with that.

Important, I'm using 95oct fuel, and It's not in my plans to use 98oct.

Is fuelling following requested though?

Have you got logs?

What is your requested and actual boost? Provided you are really not going over loads much more than 150 you should not be pulling timing, unless the values are already high..

Of course I've got logs

I logged several things, about your questions:
Requested and actual lambdas are matching nearly perfect
Boost does too, but at higer revs, actual is more or less 0.1bar smaller than requested... I'm pretty sure is due to the higer load requested than obtained at this revs (Req=150max, act=143 max, or so). But I'm requesting that load beacause, without any logycal explanation, If I put requested load the same values as my actual load now, the actual load decreases. I don't know why, but it's like this.

My n75 map is stock, Should I modify it?. Taking a look at this log I think my n75 actuator is ok but this higer revs with quite less duty cycle than 90s%... makes me think


Keep in mind that my LDRXN map is a bit uncommon, I don't request very much load at low and low-medium revs... it starts to rise after medium-high revs. I do this to not produce lots of torque and cause damage to my clutch

Try lowering fueling to .78 at 5000-6000 see if it clears up your knock retard

So post those, not just a screenshot of your csv file Tongue

I keep trying to explain this to you Sad

ONE MORE TIME:

THE PID DOES NOT CORRECT BASED ON LOAD ERROR

It corrects based on lde (boost) process error.

There is no feedback loop in ME7 that compares actual load to requested load.

1- I didn't post it because you don't like vcds logas and I made them with that, anyway, here there are the logs.

2- Yes, I know, you told it to me... that's te reason for mapping LDRXN like that. But I don't understand why there's an actual load measuring block. It's a calculation?, It's wrong then...

3- I think (maybe i'm wrong) there are some n75/wastegate actuator map, based on rpms or whatever. Otherwise I can't understand why the duty cycle at hig revs isn't 90-95%

1) the load->boost calculation is an approximation
2) the MAF/RPM->load calculation is an approximation

In ME, measured load and specified load are completely separate.

PLEASE RESEARCH WHAT LOAD MEANS before doing any more tuning!

Load is the cylinder filling. In theory, proportional to boost with an offset, in practice, simply related to it.
I'm not using an already existing XDF, I made myself the definition file with the very only maps I know, so I can't touch any unknown parameter.
I'm tuning KFLBTS, Lambda tarjet once exceeded EGT threshold. Richer mixtures prevent from knock, so adding a bit of fuel I'll get rid of those timming retardations, and of course, KFFDLBTS is 0 to ensure specified lambda is only managed by KFLBTS
Now the n75, full DC = Closed wastegate, the less DC, the more opened wastegate. So now it comes the question: If the car demands more boost than obtains, why the n75 DC is not 95% (At this hig revs)?

I think I'm right in my comment, If I'm not, all the corrections are welcome.

I limit. Please review how PIDs work.

Also, please consider using ME7Logger, you can't log all the PID variables with VCDS

Thank you very much nyet, I've just taken a look of it and seems to be exactly what I was looking for. This night I'll read it carefully and also s4wiki related things

And I know, me7logger is a must. I have to use it. Even It's easier for the members to take a look than a cvs file

Aggg, There's a subject in my degree (Industrial engineering, I failed this subject) called Industrial Automation wich I particulary hate. The last part of it is about controllers, for example PIDs... Learning to remap my car is gonna help me with that hahahaha

I Suposed to... me7 likes corrections too much

As I see, It's something like (Requested Lambda) = KFLBTS + (KFFDLBTS * Another map that I don't remember), so zero KFFDLBTS makes lambda tarjet following exactly KFLBTS ?

Sould I zero/one that maps? Or is better to leave them as they are? The PID correction ones, I mean. Well, maybe It's already explained in your link, probably a reply is not needed Wink
