From the dumps(xc90 2.5d is aw55?), execution starts at address 0x1000, but what is at 0x0-0xFFF?
It's from TF80 gearbox. Sorry can't share low addresses code because the guy who share these dumps with me doesn't allow me to share these addresses. But if you have SBL for temic and aisin TCU's then it's doesn't matter. Because flash address starts from 0x8000. We found adaptation limits for TF80 s60r flash and I tested it on my gearbox. Gearbox starts to work much better. Some adaptations were on the egde because gearbox has 300+ thousand km. mileage. And adaptation limits from factory looks very narrow. TF80 for p3 platform has problem with teflon rings. And from my point of view the problem isn't with rings but with adaptations. It's very strange that growing of leakage on few % can dramatically spoil the behavior of the transmission. |

So there is more code at 0x0-0xFFF but you are not allowed to share? Thanks. Well it be a while, I will try to buy a Temic ECM to dump these parts. What is an adaptation limit? Btw, here are some tips for reverse engineering SH-based devices(also Bosch aka EDC). There is a plugin for Ghidra called GhidraEmu which can emulate instructions(yes like HEW), it emulates the Ghidra P-code so it's actually platform agnostic, it's never going to replace the actual device duh, but it can help in my opinion. It is especially useful for things like the SBL, because you can write it to ram, and then dump the entire RAM, load it into Ghidra and emulate with more or less correct RAM values, there are caveats but it is nonetheless useful. |

It's ms or pressure constant. Depends on adaption parameter. Sorry can't give addresses but it names like this. |

Swapping to M66 isn't good idea. It's better to swap to TF80 and tweak TCM and ECM.
care to elaborate? i strongly prefer manual transmissions, on any vehicle, but here in canada manual vehicles are relatively rare to begin with. i'm starting the swap today, and am also prepared for CEM modification, clutch switch wiring to the ECU, reverse light wiring, and modifying my stock bin from automatic to manual |

If I want to change idle AFR I have to edit only LAMDSK?
Or something more?

M66 transmission is weaker than TF80. Moreover aw55 can handle 500 Nm during 30-50 thousand km. Yes with enabled limiter and stock ECM flash s60r is very slow. But after disable limiters and small boostup car becomes much funnier. |

You have to modify some constants in the code. I posted WinOLS file in this thread with my learn burn modifications. |

That does not match with my observations over many years. We drove an M66 AWD with over 800 Nm on drag strip several years. Then many with around 600..650 Nm in daily traffic and with top speed on Autobahn. Sure, you need SMF and better clutch, but that's it. Besides that, input shaft of AW55 broke at 520..550 Nm. Not tried this with TF80SC. So no general rule i would say. |

Ok, what 1/4 mile time do you have on 800+ Nm? About TF80. Software has 400 Nm limiter on first two gears. On 3-6 gears limiter sets to 600 Nm. It's from factory. I think that this gearbox can handle 700-750 Nm for a long time. With raising of linear pressure will handle more. |

Either it was just pure coincidence or you really did find the limits of the AW55. What did you do to break it? |

Launch, what else  It happened more than one time, same on AW42, which is basically the same construction. We had reinforced from Level10. No luck either. We did drag racing with all this stuff on P80, P1X and P2X since 2009 - i guess we pretty much tested all this out a decade ago  Time with M66AWD was between 10,9 and 11,2 s. No lift shift i patched in wasn't working proper those days. Broke drive shafts often. We then skipped to sequential race shifter with dog box when engines went over 1000 Nm. I don't know how much is still in the internet, "we" were VPerformance... |

One guy told me that Volvo transmission, engine mounts and cardan can't handle so much torque. |

I don't know how much is still in the internet, "we" were VPerformance... Well I am almost positive that Level10 did not install a reinforced input shaft. So basically, you can have 500+nm on the AW55, but never launch it? Sounds like dougy was correct. He got 690awhp but said he never once launched the car. Not sure if he used AW55 or TF80 however. |

As i said, there might be some videos for "VPerformance" left on youtube. I can have a look for csv logs i made those days when some time is left on holidays. Sure, you need supporting mods on car to support that torque. You can not have 500 Nm on AW55 very long in my opinion. Depends on the use case. Selenoids die, shift plate washes out, burned bands. Oil change all 5000..10000 Km for sure. TF80SC might perform better on long term under those conditions but will need maintenance more often than stock in my experience. Merry Christmas |

This is brand new for me
The MS43 is quite worked through and is far easier for a starter. I am currently comparing maps with a really good ols from a S60R and a S60 Stage 1. Seems like most maps are close to eachother, others harder to find. I currently work on the older 98-00 Me7 found in late S70,V70 and early S80. For a beginner like me, this thread has helped me a lot. I am now more aware of the things I do not know lmao. anyways...
What are the biggest difference between the 512kb and 1024kb Me7?
The Bin is from a B5204T4 120kW/163hp. It is going to be tuned into the italiy T5 aka B5204T3.
Could someone verify my maps attached?
I am struggling to find the following maps
I would appreciate a pointer in the right direction or if someone got the spare time to look through:
LAMFA
LDRXN
KFDRL
KFLDIMX
FKKVS
