If I change some values in my 50GPHJ bin in the following tables, the values in the table do not correspond to what I see in the logs. Can someone please confirm that the addresses for an EU 50GPHJ bin are correct:
KFLBTS
address: 19B5A (8 bit, HiLo, not signed)
rows: 23500 (16 bit, LoHi, not signed) - 12 rows
columns: 19C1B (8 bit, HiLo, not signed) - 16 columns
KFMDBGRG
address: 216E8 (16 bit, LoHi, not signed)
rows: 216C2 (16 bit, LoHi, not signed) - 12 rows
columns: 216DA (16 bit, LoHi, not signed) - 7 columns

Addresses are ok. There is more to fueling then KFLBTS. There is also KFDLBTS (addition), LAMFA, ATR (addition), warmup-fueling, cat-heating fueling and so on. Mainly it's LAMFA. BTS, ATR but it depends on software version. |

Thank you for confirming. In that case, I don't know what is going on as my BTS map (specifies 0.797 @ 183 load) is already a lot richer compared to the lambts_w value from the log here at 216 load. Shouldn't it be at least richer than my actual BTS map, because the addition can only add fuelling? What could be another issue causing this?  Also with regards to the KFMDBGRG map, the ECU does not seem to limit any load based on the gear according to the logs (the KFMDBGRG map limits the load based on the DRX, correct? So 70% of power means 70% of DRX at that RPM). |

Also catalyst overheating protection can rich mixture. To disable it you should set CATR codeword to 0. CATR addr = 0x18A04

What could be another issue causing this? Lowpass time filter that limits rate of change for example. Btw always post logs instead of screenshots of some random tool. |

I logged the car again and flashed the ECU with a weird oscillating BTS table just to see if changes have an effect - they do, but the targets do not translate 1:1 from the table to the log (e.g., requesting a minimum 0.81 lambda @ 6000 rpm through KFLBTS results in the ECU setting lambts_w to 0.84 @ 6000 rpm). Furthermore, even though my CWTATR is set to 0, the ECU seems to request a rich lambda on deceleration through lamsbg_w, which table would request something like this?

Happy New Year!
Just wanted to drop by and say that. Not to go off topic, but it's been a little over a year now I've been reading this thread over and over just about every day, and I wanted to express my appreciation to you all for all I've learned. Because of this site, this thread, and the people therein, I've learned to do some pretty amazing things. I'm not going to go into detail but I'm working on some pretty deep stuff, and I remain committed to giving back to the community rather than using this info for profit.
Thank you all, and keep up the great work!

I am thinking my BTS fuelling is not working 100% because of cross flashing to 50GPHJ instead of changing the 50WRHJ the car came with from stock (I don't have the correct parameter log file to log on a 50WRHJ).
I flashed back to a 50WRHJ file and the car is driving much smoother. On the 50GPHJ file, the car had checksum errors in the ECM plus a not working rain sensor (for 9 months on the 50GPHJ file I had a not functioning rain sensor and now the minute I flash to the 50WRHJ file, its working again). I have no idea how the rain sensor and the ECU software are connected.

I have no idea how the rain sensor and the ECU software are connected. I don't think that is the reason for the BTS fueling not working right, logging in more detail I am sure it can be easily found. That said, I have support for 50WRHJ in my logger if you want to go that route. |

Please be aware, that since 50WRHJ new software versions are not named correctly. A different scheme is used to distinguish them.
There are at least four different versions of 50WRHJ with different software layout. And different diagnostic ids.
Best way in my opinion is to request or compare diagnostic id, which tells you which memory value is which diagnostic id.
Regarding BTS: there are some error paths which trigger different behaviour in fueling / BTS. They might got triggered in your cross flash environment. But what you describe sounds for me like cat protection or head protection which has a higher priority over BTS in Volvo files.

On those ECU's where there is EPK present (search for /1/) you have to use the EPK to identify the ECU. But what you describe sounds for me like cat protection or head protection which has a higher priority over BTS in Volvo files. LAMKO is a minimum selector... |

Yes, EPK is also a possibility.
Just checked them, four different EPK Strings.
Sure, minimum selector. Priority is probably the wrong word to describe Lambda selection correctly.

Just checked them, four different EPK Strings. Not really a "possibility", rather the only correct way to do this for ram logging. There's a lot of software with the same EPK and it makes zero sense to have separate definitions for all of them. |

For US we got a final update 50GSHJ 05+ manual 05 auto which runs really good.
Works on 06-07 tf80 cars but no cruise control in 6th gear so we still use the wra72 wrhj variant for those.
Cross flashed many, never any issues
