Guys,
What do the numbers on the right of the ECU mean? (please see photo)
I am looking to buy a used ECU similar to my S60 2.0T and do all the testing and read/write on it prior doing actual work on the car but would like to know if they are compatible so I don't have to find the maps all over again in my car.
Mine for example says 03169 instead of 04139 on this one and 0000044892 instead of 0000157769. Will the binary be the same in terms of structure?
Thank you

That's a unique serial number, and doesn't tell you anything. The serial number is also stored in the flash chip.
The part number above it will get you closer hardware wise, but can still contain different software.

Thank you rkam. So can I use a same part number ECU but with different those numbers and clone my original one? I would like to use my original as a backup and work on a new one, cloned (bin+immo).

I apologize if this is the wrong place to ask this but it fits the theme of the thread I think.
Has anyone tried flashing a stock R bin to a 2.5t car? Could the 2.5t be run with the R file without any serious codes (pass obd2 emission test) of the R k24 and injectors were also swapped over? Or will the different tune cause issues because of the lack of 4c, etc?
Furthermore, could a R tune be flashed to a 2.5t xc70 as an inexpensive way to get manual transmission and k24 support?

2.5T must be Decos ECU and also need R MAF. Different MY have different software structures too.

What do you mean by "Decos Ecu"? |

Some Volvos use a fixed fuel pressure and some DECOS. Google it  |

Dear fellow Volvers, I received my spare ECU some days ago and now have some time to play with it. The first thing I want to do is bench flash it. The part number is 0261207712. As for tools i have 1)MPPS v13 2) Galleto 1260 3)Volvo DICE 4)Awaiting VagCom Reading all over the thread and the internet the only info I can find for boot mode is a picture that is different from my hardware. The picture is this one: https://vignette.wikia.nocookie.net/the-me7-project/images/d/de/20161220_181815-0.jpg/revision/latest/scale-to-width-down/1000?cb=20161225102356And mine is like that. Do I still ground pin 24? Is it correct? https://imgur.com/a/pkc0lThen, how do I read the immo code? Do I use Argdub's me7 EEPROM programmer tool? THANK YOU!! |

Hy guys,
I've been an owner of an '03 S60R. It is stock beside an FMIC. My father got himself also an '03 R, according to chassis number there are only a few days between the two cars.
My problem is: this car only boosts to 0,6/0,7 bar max. No boost leaks, no vac leak (0,7-0,8 bar vac). Checked sensors, TCV, MAF etc. Replaced TCV (clogged), and replaced IAT sensor (showed almost 50°C more than the real value). I have a Vida/Dice combo and did some measures. According to the desired boost in Vida, everything is "fine", desired is only ~1700 hPA, TCV duty cycle bumps to 86%, then instantly reduces to about 50%. Do you think this car has a "detuned" software?
According to previous owner there were a BSR map on it. What does it have now? I have no idea.

If it’s a 5-speed automatic then those have less power yes. Factory detuned.

Any fault codes in VIDA? When you say you replaced the IAT sensor, I assume you mean boost pressure sensor as they are all-in-one.
Do you happen to have the part number for the sensor you bought? R and 2005+ T5 P2 models have different sensor compared to other turbo models.

Yes, BPS sensor. Bosch unit: 0 261 230 295.
I had a low boost fault code with the clogged TCV. No codes after the replacement, but still low boost.

Seems correct.
Have you read your ECM? What kind of boost is it requesting? I assume you are here to tune it?
