Summary of change:
'''This page lists important changes to the firmware. Check this before downloading a firmware that is meant for production''' '''VERY IMPORTANT''': for any firmware, the '''VemsTune MUST be newer than the firmware''' (see File / Firmware info). * Only use older VemsTune (at your own risk) if absolutely necessary and you really know what you are doing. * "Help/Manual update" only updates ini files, which is not enough in all cases. * Old vemstune (sometimes even with updated ini files) might not warn about important misadjustments, or might not show some settings at all! (No surprise it does not show values added in the future) ** Sticking with and old VemsTune (that worked perfectly for some similarly old firmware) after upgrading to a new firmware is a very bad idea. Actually it is '''best to install VT first, and do the upgrade with the new VT !''' * '''new VemsTune applies some useful config changes''' when old saved config (eg. 1.1.85) is uploaded to newer firmware (eg. 1.1.96). This saves a lot of time and headache ---- This page is normally updated by development team only. Unless it's something obvious or minor (eg. spelling), do not edit this page without reading this: * For install-related problems (like needing to upload firmware after bootloader upgrade) use your own MembersPage. * For generic (hopefully reproducible) issues, see IssueReports. * Feature requests moved to GenBoard/UnderDevelopment/FirmWare '''IMPORTANT: when uploading new firmware''' to a controller (even with a motronic55 connector!), to prevent filling cylinders with fuel or possible igncoil or igndriver damage: * '''remove ignition fuses''' (especially important if uploaded firmware is 1.1.85 or older) * '''remove injector connectors and remove fuelpump relay''' ** or otherwise make sure the fuelpump is off, eg. hidden anti-theft switch ** (especially important if uploaded firmware is 1.1.85 or older) ** Upload and verify Firmware ** Upload and verify config, and measure voltage in the injector connectors before powering the fuelpump ** Explanation: when table positions change inside EEPROM (as between 1.0.73 and 1.0.78), the h[0] and h[2] might get corrupted (might fill the cylinders with fuel). * to avoid filling cylinders with fuel (or other problem), '''after firmware upload, always upload config and tables''', reboot, verify, measure, than power ign and inj only if all is well. ** always upload config after firmware upgrade - even an unrelated old config from a very different setup is better than nothing. Do not even try to set everything manually without a config upload. It will take many hours or days, and it will not work ! You have been warned. It is of course recommended to go through all dialogs, but only after uploading a saved config. * '''but first of all: READ EVERYTHING BETWEEN OLD AND NEW REVISION''' and check if any of the changes affects your configuration. Take action if necessary. For example, if you used an 1.0.13 firmware, and upgrading to (eg. 1.0.23), when reading through all changes for intermediate releases, you will see (at 1.0.14) that fuelcut_min_kpa must be adjusted reasonably. If you skip 10 mins to read through, you'll sit in the cold car for hours and wonder why the engine does not start and notice injector pulsewidth is 0. '''You can report problems/bugs on this page:''' IssueReports ---- '''Users upgrading to 1.0.36 and above please note:''' There are some issues with the ALS configuration that may not be apparent when upgrading your configs from an earlier version. These are detailed MembersPage/GaborRacz/NewAlsLaunchAndOthers Windows users have an easy solution to solve this issue detaile at MembersPage/PhatBob/ALSConfigFix ---- '''Downloadable firmware releases'''. These are not intended for compilation. See SubVersionSvn if you want to get involved in development. Publish the my_make on your MembersPage if you just want a firmware compiled with some special options. The "Genboard Public Licence" allows modification of firmware (algorithimic changes, additions etc) if the modifications are sent back to authors. Much of the sourcecode was published, and everyone so far who sent modifications got read-write access to the firmware tree. Because of repeated (intentional or unintentional) violations of the copyright, developers decided to apply control over the sourcecode that allows well-intended use but prevents violation * "normal" customers don't (and shouldn't) need to modify firmware * anyone with skills to modify firmware who want to do so: apply for access. See SubVersionSvn . Don't forget to detail your plans ("I implemented / I want to implement ..., concept is ..., any simulations, or PC-testcode, etc...) ** the plans are necessary so the team can cooperate with the applicant to sort the necessary files/functions for which access is needed for the given task. The development team attempts to cooperate. Access to the chosen functions is granted after the development team decides that cooperation is likely to work out. * an NDA is necessary that allows modifications (algorithimic changes, additions etc) for self-use or use in reselled VEMS products, but does not allow carrying the code (or concept) to competitive products. '''Changelog''' - missing tooth trigger installs (N-1 or N-2 with or without camsync) and InputTrigger/AudiTrigger (135+ tooth wheel) users (especially with big-ignadv-window ALS), extrapulse triggers (some honda and homemade triggers) and all VVTI (camshaft-angle-control) and table-switching apps will likely prefer 1.1.x * 1.1.x always supported 60-2 trigger and supports dual config since 1.1.3x (read below). * very few will use 1.0.x now ** 1.0.x is unlikely to ever support TableSwitch '''IMPORTANT: use new VT, or at the very minimum, update VT ini files from web''' before upgrade (especially if upgrading to a firmware newer than VT) and '''check validate after upgrade'''. * '''Without VT ini update (eg VT older than firmware) don't expect that it works''' (in some cases it might work, never assume that). * minor manual interventions might be needed (that will be automated in some future VT ini). ** Eg after upgrading a simple-coil trigger, if the extrapulse or ls4 config bit (these bits are "don't care" in earlier firmwares) is enabled it will give no spark. '''When upgrading to non-released firmware''' (eg. 1.2.15), the following steps should be applied: * start with a tuned engine running well on '''earlier firmware''', either latest released (eg. 1.2.11) or newer (eg. 1.2.14) * upload the '''new firmware''' (eg. 1.2.15) * optional: upload the new version ( from experimental/ or X/ directory if necessary) * enable the '''new functionality''' in config Do some testing (at least a spin around the block) with logging in each step. Report should contain the sequence (eg. GOOD, GOOD, GOOD, WEIRD IAC oscillations; with '''vemslogs''' for all steps, at very minimum for problem cases). ---- '''[http://svn.x-dsl.hu/f/ 1.2.42]''' - experimental, do not use yet (unless for testing, after project page + review). * receive multiple analog and wheelspeed data via 2nd serial (when enabled in config), while also sending AIM via 2nd serial (possible for multiple receivers) ** most useful when controlling 4 camshafts (quad vanos) and 2 CAN-bus (eg.
