Here you can link your report issues with your Genboard V3, firmware, tuningprogram or hardware problems.
Make your report on your MembersPage, and place link in the relevant section (with a "title", so it can be remembered easily). If you dont know the section, put it under "Unknown".
In the report, include a short entry and description + URL to your page, where the page contains:
- .vemslog or .vemscfg is absolutely essential to reproduce
- any report without these will be deleted. Add .vemslog or .vemscfg
- and besides these, (especially if a trigger problem, with new firmwares like 1.1.81) also a triggerlog (so the team can get a chance to reproduce and help to resolve the case).
- Note that newer firmwares have new trigger-settings in config bits that were previously "don't care". Bad settings of these will simply prevent triggering, so carefully check after uploading an 1.0.x or 1.1.7x or older config to a new 1.1.8x firmware)
- board version, serial Nr.
- firmware version
- MegaTune version (when MegaTune is used at all)
- intended config.txt (possibly commented)
- mcdmct.txt (captured output of Manmcdmct command.) This is the live config. Very important, since in a bad case it can be different from the intended config (if you used a global.h from a different firmware version; or there is a MegaTune configuration problem, etc...)
- description of the problem
- your investigation so far
- any ideas to proceed
The report, to be considered, must contain ALL necessary info. Without the necessary info, question-answer iterations are needed, so solution is delayed in the best case. If there is not enough info to reproduce, the report is neglected (especially if it contradicts experience). Re-post with the necessary info if you believe it holds.
Hardware: - usually wiring. These are normally answered even if you only use your MembersPage, but if you insist...
- ...
Config: please use your MembersPage where the full setup (engine, triggers, whatever related) is described
Vemsdisplay 2.1 - run but no menu on ICS, on 2.3.5 works.
Vemsdisplay 2.0 - fail to start on android 4.0, logcat says application not found gauge table in gaugegroups.db. Seems to compatibility problem, with 2.3.5 works fine.
1.1.98 onwards (1.2.00) - 2nd WBO2 calibration and free air/ O2 display. How to calibrate?. Sprocket

Somewhat is broken in 1.1.96 classical Auditrigger. Cranking before first sparks prolongs approximately twice more blank revolutions. I note that on two cars. and today downgraded last one to 1.1.95 - it clearly improves situation to common. GintsK
Confirmed, 1.1.96 cranks much longer than 1.1.95 with the same config file. KeithJ
Confirmed again, 1.1.96 takes noticeably longer time before starting compared to 1.1.95. Mattias S.
This is fixed in 1.1.99, but instead serial communications drops all the time. This makes tuning rather difficult. Everything is the same except for firmware version, switching back to 1.1.95 makes it work fine. KeithJ
Something is still up with Auditrigger. Lots of misfires on 1.1.99+ for a config that works perfectly with 1.1.95. It acts like there is a rev limit way below the set point, and misfires really easily even at low RPMs.
1.1.95 now and running ok. However i see that the knock sensor features that were on 1.1.88 are now completely missing. Is there any options for knock sensing and updated settings that can make VEMS use the knock sensors adequately?
thanks
1.1.95 - No menu options for wheelspeed running latest nightly VT 7-12. Checked Firmware Parameters and it lists a 1 for PS2. I then downloaded both 'wheelspeed' & 'ps2' firmware to vems and neither of them showed a 0 for ps2.
1.1.94 - solved: use non-PS2 if wheelspeed is needed
- went from 1.1.88 to 1.1.94 as recommended and using vemstune 16/6/2011.
- Speed sensor feature is completely missing from my saved config and i am not allowed to see it from base menu.
- Likely you selected PS2 firmware that does not have wheelspeed sensing (the PS2 clock uses up the 1st wheelspeed input).
- Other users do not have this problem.
- yes, just Choose non-PS2 firmware
- actually, Sami reported that his noisy (mechanical reed-relay type audi transmission) wheelspeed sensor reading is not stable with 1.1.94 when input prells at 450 km/h period (he provided suitable triggerlog to see this) and in 1.1.95 we implemented a more advanced wheelspeed filtering that fixed that sick case: you can use 1.1.95 non-PS2 also.
THANKS> im going to go with 1.1.95 now. I thought i was supposed to use PS2 and not non-PS2(dont understand the difference). I would also appreciate if you could point out where to look for knock sensor settings for audi, as well as speed sensor settings for audi 5cyl engine. Thanks, Vasilis
Firmware:
- v3.1 #56 & #57, 1.1.70 I have a problem with new firmware on 3.1 board. It only works in limphome mode.
- using latest Vemstune (2010-03-08 and 2010-02-05). The problem is that after startup spark angle stays fixed on 10° all the time
- similar situation with stepper IAC valve. When I turn on the engine it goes in max closed position and stays there
- 3.1 boards are still supported. It's a bootloader problem. Was the bootloader upgraded (or atmega changed) on these boards ? This "limphome" protection was implemented by Andrey, ment for a batch of pirate boards (most in Bulgaria and Russia). If your board is "genuine" (even if old), contact through WebShop (so you can receive a new bootloader, or other solution). Write the original Order-ID or other details (date of purchase)
1.1.88 knock_chan setting of 168 resulted in an increase in spark advance. vemslog and additional data here: http://www.vems.hu/wiki/index.php?page=MembersPage%2FMarcSwanson%2FFirmwareBugs
1.1.81 anytrim for boost do not work as expected. Boost target is boost dependant. Here is deeper description + real life and bench test .vemslog http://www.vemssupport.com/forum/index.php/topic,1490.0.html GintsK
Thanks for the Error report, problem found and fixed in Fw 1.1.86
1.1.75 and up
Trying pure alpha-n without using map signal. It was believed an VE (TPS/RPM table) interpolation problem:

Solution: Dynamic VE table in group
Dynamic VE table means automatically change the Y axis based on current config Speed-density or Alpha-N.
To use it in a group properly you have to select Edit Mode and add Super table or Super Table 3D instead of Table and Table 3D
Problem with sd logging in 1.1.85. The Rpm and map values logged corruptly with sd log, when normal VT log seems fine:
