Hi everyone, name is micheal from south africa, been in the motor mechanic trade for 15 years, own my own bmw and german car workshop and getting a lot of requests for tuned files and this seems to be the best place to get this info.

I have a tuned jetta file from my own car that was done when i bought the car, i was wondering if anyone could help me identifying the maps on this file. see attached file.

Thanks and regards micheal

SW ver and ORI?

In fact, it's a TFSI file. It's KFLDHBN. Max pressure ratio. Common for this to be maxxed.

thanks for the info will do some homework.

Only common in shit files.

Bearing in mind without a shit ton of ASM, it's not possible to request load on these ECUs that will result more than 2550mbar absolute. To run more boost, sacrifices have to be made. Explain how that map could be correctly calibrated with all the load management routines fully active. Thus far, I've not seen it done.

What does KFLDHBN have to do with 2550mbar?
Go look at the factor for it again and the max value, and then realize yourself that you have no idea what you are on about.

Also, if I want to run more than 2550mbar on this ECU, I run more than 2550mbar on this ECU.
People who can properly tune these cars do not make "sacrifices".

Even if you did it completely backwards, there is nothing stopping you having a correctly calibrated KFLDHBN.
The fact that you have not seen it done, means you have never in your life seen a proper tuned MED9 file..

Not that this 2550mbar stuff matters to the OP in the slightest, as you are never going to hit that on a stock car.

Agreed the OP is probably not going to hit this limit just now, but I was keen to digress slightly so you could explain what a sane KFLDHBN would look like on a highly tuned file.

I'm talking about the circumvention of the load management system itself. To get and sustain more than 2550mbar you need to hijack PID and drive the duty cycle directly. Again, without some machine level code changes, you're not going to do that with standard Bosch code and load management. So my point is, directly driving the duty cycle is making a sacrifice (for the purposes of running the desired boost). Why is KFLDHBN being moved up and out of the way a shit choice when its impact is going to be limited anyway on a hacked PID?

For the final time. KFLDHBN does not limit req. boost, it limits req load.
Please, just stop and read the FR.

I know, but what does load then translate into???

cylinder filling

I think you know where I'm going with this. Eventually it boils down to requested boost.

That depends on the turbo that has to fill the cylinder, so its not exactly as you put it. A larger turbo will fill the cylinder with less pressure. What is measured to determine the cylinder filling?

I think you need to re-read what I wrote and then read the FR.

1. KFLDHBN has NO effect on the 2550mbar "issue" whatsoever, as it limits load not boost. It's exactly the same limiter as LDRXN, just expressed differently.
2. 2550mbar "issue" has NOTHING to do with requested load.
Hence why I called you out on your bullshit.

You don't even know the very basics of how this ECU works and you want to discuss 2550mbar limitations? Talk about trying to run before walking.
Get off the forum, go and read the FR and educate yourself. If you ever get WHY you actually can't request more than 2550mbar, then you will see that your claims are ridiculous in retrospective.

I think he's saying if you are going to have req boost ride the 2550 limit, you'll need to get HBN out of the way, and using HBN as a safety feature to limit boost (through limiting req load) is pointless.

He's right on both accounts, imo

A better question is: why on earth would you want to ride the 2550 limit?

Thank you, probably better worded than the way I had it but prj's arrogance (entitled or not) was starting to drain.

The 2550mbar limit is a soft limit on the K04 cars. They have 3bar MAPs so you can hijack the PID to drive it above 2550mbar.

Just dropping in a 3 bar MAP does no such thing :P

It's not dropped in - its standard. K03 based TFSIs are 2.5bar sensors, K04s 3bar. So will measure / see pressure above the requested limit.

The 2550mBar limit is generally in the ME7.x context, where it is hard limit in the ECU.

What is the ps_w scaling on the ECU you are talking about?

You are wrong. Again, it does not limit boost, it limits load, and ME7/MED9 cuts throttle when rl exceeds rlsol. Boost is completely irrelevant.
Does not matter if you ride req 2550 or not. Whatever hacks you are using (even if 2550mbar = 3000mbar or whatever), you can still use KFLDHBN to limit load to sane values at high IAT. Look up ldrlts in the FR.
There is never any point to max this map apart in piss poor tuning.

Soft limit?
ps_w scaling is max. 2550mbar. plsol scaling is max. 2550mbar. Nothing soft here, it only displays the sensor value and does not do anything with it.

There is no arrogance here, the only thing this thread reeks of are ignorant people talking shit about things they do not understand.
Go on then...

I had a BSR stage 1 map on my old S60 2.0t. KFLDHBN maxed across the board...

Then again, it also had a random 0 value at high RPM in KFLDRX.... Funny.
