The SimosWiki
This site is dedicated to tuning the Simos(18) family of ECUs commonly found in the MQB platform of VW/Audi cars.
Most of the information here revolves around the use of Eurodyne Maestro. Eurodyne does change some maps and axis names, but the vast majority of ecu strategies are kept consistent with the way Continental designed it. An example of where there's a change in the software is the Boss file wastegate duty tables. The factory uses a complex scheme to calculate the exhaust flow vs Boost, while Eurodyne changes this to use a simple RPM vs. Boost level. Examples of the two different tables are on the Eurodyne Maestro Tables page.
THIS WIKI IS A WORK IN PROGRESS. We went live with it on 9/21/2020, and we're working on getting info in place.
