(Writing from memory, travelling without my laptop). On ME7.9.10 which supposedly has a very similar boost control, the cw is CWMDAPP, will confirm later. The downside of KFTVLDST is that it is full open loop, at least on ME7.9.10.
While at it, any of you could share the parts of FR that treat boost control? Either for the discussed MED17 or ME7.9.10 or equivalent.
Completely wrong. CWMDAPP is not the codeword and it is possible to set only the pre-control to that map while keeping full closed loop PID. |

flash_085B6A:[F6,F4,82,A3] mov tvldste_w_wastegate_DC_0F2382, r4
There is no PID control over the value read from KFTVLDST whatsoever, there is one over one of the pre values (wastegate strong, turbine mass flow, and what not) that lead to what I marked as mapres_TVLDSTDPW_0F23DA. And yes, that is for ME7.9.10, not MED17, in another post I explained that looking at MED doc tells me it's a whole different story, which I am sure you can explain in detail to everyone  Apologies if my variable names are not up to your standards, I know some of them are wrong. |

MED17.5 works completely different, and this is what we are discussing here, not your fiat ECU.
I don't see why you keep bringing up an ECU that is two generations older when we are talking about Tricore MED17. MED17 is nothing like it, and MED17.1.1/MED17.5 are also completely different between each other.

Well, you said in another thread when I asked about ME7.9.10 boost control "sounds like MED17", clearly not, I wrote what I wrote still believing that's the case, and rectified my statement shortly after I found out that it is not. My mistake is stupidly believing Bosch would have and consistency in their developments.

ME7.9 has boost control somewhat similar to MED17.1.1, albeit with some differences. MED17.5 discussed here is a COMPLETELY different animal.

You must be new here. Don't expect a straight answer regarding a platform even remotely profitable. You'll get enough fluff to say "I know more than you" and the rest is just shit. It's just a cock waving exercise by some well informed virgins.  |

Registered ages ago, active long enough to see what is going on. No worries, I don't mind, my culture of origin taught me to bear much more than that |

I did some testing and left KFPWG OEM making minor adjustments to KFIWG.
At first it seemed satisfactory, I will walk for longer to evaluate and put the result.

Anyone got the MED17.5 FR and willing to share?
I'm not sure how people get hold of the FR legitimately anyhow - assuming its still new enough tech for people to want to charge for it which is fair enough!

I think you need to go back to the hole you crawled out of and come out when you actually know something. I did not have FR when I tuned this ECU. I reverse engineered the PID control and the configuration from the tricore assembly using IDA Pro. Sorry if I don't remember every single parameter and variable name off the top of my head, because I don't tune this old shit most of the time. For those actually doing some tuning - if you know how MEDC17 addressing works, look at the access to IIRC the first parameter in the module. If the turbo is changed then just changing the PID will not help you when the precontrol is massively wrong. |

Case in point. If the shoe fits, and all that. Considering I don't do tuning for a job, I feel I know enough and am happy with my rate of learning as a hobby tuner. You're the equivalent of a chief engineer at Boeing coming onto a model aeroplane forum and waving his willy about. It's been stated that you have a "unique type of arrogance". I think that stems from the fact that your mum has given up trying to get you out the spare room. |

Keep talking. You have absolutely nothing to contribute, but you really can't keep your mouth shut. Class. |

Absolutely nothing? That's wildly inaccurate. I contribute what I can, where and when I can. I love the "can't keep your mouth shut" comment. What relevance does that have? What authority do you have to tell anyone to keep their mouth shut? You're a cock, and a monumental, smug and arrogant little one at that. One that I dare say wouldn't have the minerals to talk to someone to their face as you do on this forum. |

Keep talking, we're listening. Anything else useful you have to say? You have contributed absolutely nothing to this thread apart from being an obnoxious twat. |
