Hilda HR I – ECU Recalibration Index

History of changes during ECU recalibration process on Hilda HR I. Sadly, I was lazy to do proper documentation and some data is missing such as distance from odometer. I also wonder why the hell I have used so many versions ROFL

Skoda Octavia HR I - rear detail

PLEASE READ WARNINGS BEFORE YOU PROCEED !!!

IF YOU FIND INFORMATIONS USEFUL, PLEASE CONSIDER DONATION.

I have no idea why did I use wild version numbering. In the beginning I jumped from one major version to other and by the end I finally did it programmer style. Fine tuning subversion and only major changes got a new number.
