The same firmware and MegaTune that was used back in the old days for GenBoard/VerTwo (in 2003) should work today as well. Limited a bit, since
- v2.2 hardware is just a bit more advanced than the original MegaSquirt, comes nowhere to v3.x
- MegaTune was also harder to use with it's own tricks and watchouts
- TODO: find latest working and tested ver2.2 firmware that compiles cleanly.
- as a last chance, try anonymous CVS from sourceforge
- making stable1_0 branch compile for v2.2 should be relatively simple. Start from a recent released (or a newer, yet unreleased if exists) from http://www.vems.hu/files/Firmware/release/
- always publish patches in diff format (made with diff command)
- publish what the patch is against
Made a diff file for firmware version 1.0.18. look here http://kotisivu.dnainternet.net/sakrkorh/fw/ . Just commented out few things which I don't have any idea. Now it compiles but haven't tested yet. Boostcontrol is difficult to go around cleanly.
