Any chance you can get more samples, with different voltage values?

in ME7.1 on audis, voltage is generally 1 byte, where 12V is 171 or 0xAB (scaling is 0.0704), like you said.
No clue why you are taking the top four bits. I'd use all 8 bits:
result = (msg->data[5]) * 0.0704
but hey, that would mean 0x48 is what, 5v?

Yes my first answer was 5V, the other values that I have figured out were all the same as you said. I'm confused. The bitshifting I posted was a vain attempt in getting values no real thinking about it... I checked and there is no change in the debug log I have here but then again it was plugged in-to a PSU on the bench. I think it best to take another set of logs and recheck my notes on the RAM locations of ubat before wasting anymore of your time  |

Is there any available data on the ME7.1 on these conversions? I'm thinking it may be a decent reference for my project.

https://github.com/nyetwurk/ME7L/blob/master/ecus/example.ecufor example, youll find this: wub , {BatteryVoltage} , 0x3808BF, 1, 0x0000, {V} , 0, 0, 0.0704, 0, {Batteriespannung; vom AD-Wandler erfaßter Wert} |

That Sir is a GOLDMINE, thank you.
I think that the data is incorrect and my original calc was correct at 5v. My harness could have messed with the voltage reference or something. I'll try the car.

Please help !!!! I readed an Volvo s60 2.5T 2004 in wrong mode only 512kb instead of 1024kb. After flashing the readed file back, ecu doesn't respond anymore. This is because I missed to read the remaining 512kb. Can somebody please send me the propper org starting with the same 512kb as in the attached file?  |

Can somebody please send me the propper org starting with the same 512kb as in the attached file? i could probably find you a file that would "work" but i recommend going to the nearest volvo dealer and getting the correct flash put back on. first off, automatic, stick? nvm, found it in your file P2X B52X4XT ME 7.0.1 4XLL sw:30641522A P2X 0310 B5254T2 25LT MAN FWD EU BLDC my S60R file will probably start your vehicle, and run horrible, how far are you from the dealer? |

Hi krazydbiker, it has manual gears not automatic. I tried really a lot of files (all aof this thread) and your s60r is working engine is starting but horrible idle because of smaller injectors. Im from germany, next volvo is 10km far from me. But do they suppy you with the right flash? I think they want to sell the complete ecu? Thank you krazydbiker  |

What injectors does it have?
I'll probably have a file close. I take it that it's a MY04 pre facelift?

Hello dream3R, yes it is pre facelift build at beginning of 2004. I attached a picture of the ecu. I allready searched the hole inet and tried at least 8 different files, but only the s60r was running...  |

I don't want cash for an ori file... I don't have exact one but if you tell me what injectors this car has I can give you one that might start and get you to the dealer without burning a piston on the way.. I'm off out so will post something tomorrow. The injector colour is normally the giveaway, I'm guessing blue... Test run for my logger today, test graph using NYET's tool but you can see it's a brilliant bit of software...  |

yeah if you can get to volvo they can do a software reload, i have done it before  , but yeah since its so far away from you dream3r has probably the best idea, find a file that starts it and tweak accordingly. |
