I'm planning on converting from Electromotive TEC 2 engine management to GenBoard version 3.2 in the mid March of 2005. Here is pics of my car [Current setup pics]

Car is a 87 vw scirocco 16v turbo

Testing genboard v3.2 against tec 2 - hoping to conduct the test in mid January.

I have to get genboard sorted out first. Test will consist of tec 2 getting street tuned for maxium effencncy and power. swip out tec 2 for genboard and street tune it and see the results. Should be a great comparasion and information data for development of future systems.

I'm going to be doing Wasted Spark igniton via a 60-2 Multitooth wheel with the help of Brian (MembersPage/GrmRacer, Grassroots car0, MembersPage/MarcellGal, and MembersPage/DaveBrul.

Here is the sensors I'll be running:

I want it setup to be a straight plug and play harness. here is some info of what I'm going to go by [ tonci loncar]

Compiling firmware: vems.hex file

For future info if anyone ever has some problems with the vems.hex file not being made you have to install both winavr and perl into your system. I'm running windows xp and I had to install both to get it to compile smoothly.

BootLoader failure report. \n

well its not working for me with windows xp.  tried it 5 times and getting the same result.
* talk in 9600 8n1
** I say Man, it responds with Hello>
** I say bye, it responds with Bye
* optional:
** Manmcbfemcb
** disconnect, connect in 19200
** I say S, it responds AVREFI1
* perl bin\prog.pl vems.hex :COM1 Etwf

after entering perl bin\prog.pl vems.hex :COM1 Etwf in Terminal I got Three "???"

I then tried Megaloader and here is what I did:
*c:
*cd bootloader
*c:\bootloader
 entered "megaloader.exe vems.hex -twE"

then here is the result:

Down loading flash file:vems.hex
LoAddr =  0    HiAddr =  9059
Translation complete!
AVR said Hello : Hello>
nothing
nothing
nothing
nothing
nothing
didn't get reply from AVR, out of sync

tried to do it on a floppy disk and got same result.
then tried to type in Manmcbfemcb.  disconnected and switched to 19200  connected typed "S" and got nothing.

Solved: Emil solved the problem. turned out that I didn't have Win32-Serialport and Win32-API libs installed. That was causing the firmware to not upload properly giving me the errors you see above. wanted to up update firmware because of needed MSNS set to use MegaTunix.

Version 0.7.0 crashed when I try to adjust setting in vital. Actually only if you tried any of the 3D views before. If you go to "Engine vitals" after startup, it doesn't crash (right?). This is being worked on. Fortunately nothing to tune there, uploaded config.mtt should cover it, those parameters won't change.

It crashes when I try to adjust # of cycinders, injector staging, or number of injectors. I can view them fine but if I try to adjust them it crashes. tried to adjust because in MTX it read 8 cyclinder, 3 injectors, and simutanious. When I actually have 4 cyc, 4 injectors, and alternate.

Only tune VE, lambda, Spark, cranking, afterstart and warmup parameters through mtx and take logs. Don't touch "engine vitals" yet (unless you are testing mtx, than verify with LCD and/or mcd and mct what was changed), and don't even believe the readings on "Engine Vitals" screen. These parameters will not change after initially configured through config.txt and uploaded config.mtt.

Parts list for Genboard v3.2

Installation notes

In the Genboard 3.2 assembled unit Firmware is already installed with the wideband activated. It is recommended to install a (released) firmware though, and not trust the firmware that is uploaded just for testing.

Here is my files if something is wrong in them tell me:

[config for 60-2 wheel]

[tables]

See injopen in GenBoard/Manual/Config/InjectorOpening. I recommend stealing injopen related settings from MembersPage/MarcellGal/EngineSwap if you have no idea.

Check the alternate=03 (are you really using 4 banks or just 2)?

While ignchmax=03 (for a 4cyl) is a good idea (so knock detection finds every cylinder) for alternate configure the number of injector banks-1.

Start with lower cwl, to decrease the chance of drowning your sparks at the very first attempt. You can increase it easily after first attempts if you think it's necessary.

Maybe it's a good idea to split the page according to subsystems and mention a few variables in\n

variable=...

right at the subsystem description.

If you can start the engine and you'll have good idle, than the first to do is check the timing with a timinglight. It's the first thing that you have to do before the tuning. -Fero
