Here you can report issues with your Genboard V3, firmware, tuningprogram or hardware problems.
If you dont know, put it under Unknown.
Any reports without firmware version and config are neglected. When megatune is involved, megatune version and megatune config-version is also needed.
Firmware:
- 2005-08-29 with firmware 1.0.15 rc1- should be fixed in 1.0.16 firmware
- boost table, first bin in megatune, alters primep instead, the rest of the table works.
Hardware:
- 2005-08-10 - Possible fried injector driver
- 2005-08-29 - This problem was solved, not genboard related.
- check connected GND5 (measure ohm between GND5 and battery-. Measure voltage between GND5 and GND when 5..10W 12V lightbulb lit through an output: eg. through an injector connector and relevant mdh.0 command, according to the h[0] table). It sounds like you still don't have GND5 connected, and it's supplied through GND (very BAD !). This is the most likely reason when injectors seem to work when injectors are not overlapping, and fail when injector signals are active in an overlapping way (injector duty > 1/ncyl)
- verify flyback: DVM, diode mode between the 2 pins of the harness injector connector (check for every injector connector)
- check all outputs with 5..10W 12V lightbulb and mdh.. commands.
Tuningprogram (Megatune):
- 2005-09-21 iac activation flag is inverted (Fero reported on phone): not sure which one, the (ON/OFF vs. PWM-stepper - likely) or ignition advance based idle active/OFF
- 2005-09-02
- EGT display (range) is bad, the gauge displays upto 256C (the digital display is good, but the gauge rails out)
- injector duty cycle... is this fixed already ?
- 2005-06-23
- Alha-n tuning is not working ? Megatune ->useing MAP not TPS load the VE-Tables.
- Ini file -> vemsv3_v13_r021.zip
- firmware -> 1.0.13 rc3
- possible solutions:
- Developers are working on making firmware report load instead of the current kpa
- If you are running alpha-n only and not hybrid mode, its possible to modify vemsv3.ini to show TPS in the realtime tuning, write here or memberspage if you need help.
- thanks for the info.I'am useing Alpha-n only, yes I need details how to modify vemsv3.ini

- Firmware -> v13rc5, precompiled.
- config + tables http://kombi.ulkhyvlers.net/vems/roland/
- LCD Display works with genboard powered, engine not started, but after the engine is started, it stops working, sometimes blank, sometimes full of rubbish
- possible solution:
- Will try a capacitor between VCC and GND on the display-side
- 2005-04-10 NanassyPeter
- Megatune Accel wizard display shows current TPS instead of changespeed of TPS.
- 2005-09-22 On Rolands BMW turbo we had some misterious problems: when LCD is reading say lambda 1 (4x20 LCD ? which page? it cannot display "1", maybe "1.00" !), megatune displays 0.94. Really weird report... Issue-reports without firmware version and config are neglected. When megatune is involved, megatune versions is also needed
