Changelog
- [VemsMT1.1.1-pre0.zip experimental prerelease]
- DONE: GenBoard/Manual/MatRetard (actually, firmware change without any megatune aspect)
- DONE: appear "MAP(load) mult" at another place where one would expect (at hybrid...RPM settings)
- DONE: h[1]
- DONE: ALS and launch input selection
- h[2] almost OK, but make sure MT resets bit0:2 and bit7
- maketables.exe should examine h[2] upper nibbles: if all are 0, than swap upper and lower nibbles to gracefully migrate to new h[2] semantics, where i259 outputs are 0x00,0x10...0x70 and s259 outputs 3..6 (stepper A..D) can be used for ignition with bit[1]>0 eg. 0x38,0x48,0x58,0x68)
- done ? merge changes in stable1_0 vemsv3.ini (curve-editor?)
- TODO: makeconfig.exe should not write unspecified vars as FF (done in svn, just need to be compiled)
- TODO: make sh.exe working: include msys-1.0.dll, maybe more. -Or probably- just leave it alone and make some integrated GUI-tool in Windows environment instead of the bunch of shells, scripts, configs, logs, readmes and troubles.

Instructions to make it work:
- download complete package above
- unzip to a directory of your liking
- use "download_config.bat" to fetch your current config from ecm or copy your existing config.txt and tables.txt to VemsMT-xxxx/config
- update your config (if required) with the config changes that may be there between the firmware version you currently used and the version you are about to upgrade to, see GenBoard/UnderDevelopment/FirmwareChanges for details on changes. YOUR CAR MIGHT NOT START OTHERWISE OR YOU MIGHT GET UNWANTED BEHAVIOUR !
- issue a "generate_config.bat"
- closely inspect the generated log files (config.log and tables.log) too see if you missed anything
- flash firmware your v3.X using "upload-firmware.bat" from the directory
- optionally run "tempsensor_upload.bat" to configure your temperature compensation tables (default is clt and iat = 2252).
- upload your tables.mtt and config.mtt to ecm using upload-config.bat"
- Reboot the ECM (cycle power)
- browse to the VemsMT-xxxx/MegaTune2.25 dir and execute megatune.exe
- select the profile that matches your firmware
- start tuning your engine
