I don't sell any "xmls", the tool is a full stack solution, and yes it outputs logs in csv format.
You can either use it, or you can wait and hope that someone has reverse engineered your software and made an xml. Btw the server defs have 4500 loggable parameters on your software version.

I have the silver bullet solution, but it will never be free, because of the monetary investment of buying a2l's and software development.
It's a little like crowdsourcing - the logger provides full a2l based logging for a small fee without having to develop the software or buy a2l's for thousands of $ or sometimes tens of thousands.

Even for these really old ME7 and ME9 Volvos it's not easily possible to find an a2l for the later variants, and an OLS project gets you absolutely nowhere, because it does not have the memory cell data.
I mostly did the Volvo protocol because I was curious how the D2 communications stack works, and because I was able to get enough a2l data to have good coverage. Financially it's not really worth it because nobody is tuning these cars.
It's there on the platform though, and I charge the same for everything - whether it's an old Volvo or a new McLaren.
I looked to your tool. It’s really interesting and great work, but not actual for old Volvo as you said. I don’t think that anybody interested to pay 50-100$ every month for log old Volvo. Maybe i will try it, but it didn’t make no financial sense for those cars. That’s why i looking for xml.

I think you did not look in detail, because if you did you would have seen that it is a $100 single time payment, and you can log forever without paying a cent more (subscription + advanced license that never stops working even if subscription expires).
Pretty DIY friendly. Most professional tools require an upfront payment of several thousands and stop working as soon as the subscription expires.

Are you looking for the WKRMA variable?
WKRMA 0xF88D

I couldn't find such a variable in the vida database.

You can find the missing variables with the ida programme.
You can also find out how variables are defined in this ida file.

VIDA unfortunately lacks a lot of important variables for tuning, knock control being one such example.

Nasty business navigating the CNG maps when you have no A2L for my stepper motor. Not only is the ECM enriching the CNG at idle causing a 0.95 and lower lambda for CNG, but this contributes to a misfire(gas displaces air) I have due to a separate issue I can't find yet.

STFT and LTFT are strongly determined by static maps than entirely by oxygen sensor feedback, so more like a guideline than rulebook. If I lower the values in both maps, Lambda goes significantly over 1(since stft and ltft compensate much less) and very lean and somewhere somehow the ECM is triggering a failsafe mode and switching back to petrol.
Because of this misfire I have + enriching, my CNG mileage is much lower than it should be. If I do manage to lean it out at idle to something like 1.09, the misfire is much less noticeable but not only is this too lean it also forces the ECM to switch to petrol.

This morning with slight changes, a cold car and slightly higher CNG pressure from the vaporiser gave me a 0.85 lambda of CNG causing my engine to choke and stall.

i've never thought of using vida for getting variable addresses. I suppose it's just done by extracting data from the SQL database? Seems like a nice method of getting a bit of groundwork done for a unfamiliar project.
