OFT log - adv multiplier = 0

I am experiencing a similar issue with ZA1JF00C. Some parameters do not log properly. For example, VVTi is all over the place and IAM is always 0. Also, when I load my base tune file in RomRaider using the .xml definition file that OFT supplied to me all I get is errors.

I found a .xml definition file on the RomRaider forum that works perfectly with my base tune file, and I can see all the maps correctly.

I am reluctant to troubleshoot by loading a tune I received from OFT into my car as the map addresses are clearly different than in my original tune. So aside from the fix described above, does anyone have a suggestion? My OpenFlash Manager completed all the automatic updates.

OFT wont log correctly till you flash an OFT version 4 tune from there website

Thank you @steve99.

What confuses me is how the ECU will know where to fetch the maps in the OFT V4 tune, given that the map memory addresses are different than in my original tune file. I assume the flashing process does not only load the tune file, but also modifies something else in the ECU such that it retrieves the maps from the proper locations in the V4 tune file. Is this assumption correct?

a lot of oft tunes are based on a different calid to your stock calid. this is why tuned roms log correctly and some stock ones dont

The ROM file is the new software for the ECU and only this is flashed - These replace one area on the ECU but the IDs that it use are different depending on the Calibration ID. How it does this doesn't really matter.
