Q: I use the latest version of MegaTunix from this side http://www.msefi.com/viewtopic.php?t=5228 is that the right? I use Windows..
A: Much is changed in the latest CVS version, wait until the next release or compile megatunix from CVS.. - OK
Q: I copyed the files from firmware/doc/megatunix to ~/.MegaTunix what else to do?
A: Remove the CVS-directorys from the .MegaTunix-directory - OK
Q: What should I do/write to get CVS to download a older version like Nov24 instead of the newest?
A: Example copied from GenBoard/UnderDevelopment/FirmwareChanges: \n
set CVSROOT=:pserver:anonymous@cvs.sourceforge.net:/cvsroot/megasquirtavr <enter> set HOME=c: <enter> cvs login<enter> ( <enter> again for password, ignore any error messages ) cvs co -D "2004/11/24 16:00" firmware <enter>
Re: ..Yes I have seen the example but I don't get it..
I have taken a screen-dump, could some one write what i should write to get the firmware from nov. 24?
A: Dont use GETFIRM.BAT for this. I've made some changes to the answer above that should get you there. A directory named "firmware" will be created.
Re: Thanks that explains.. Now it seems to work, but when I use that firmware (2004/11/24) it only write "egt:03xx" in the display.
Q: Dose anyone know why it only says "egt:03xx" and not RPM and so on?
A: Because you are on the wrong lcd page, have you uploaded config ? You can change lcd page with the arrow keys on keyboard or with the mlpxx command (where xx = 00 - 07) - Ahh.. Thanks a lot.
Q: How can I see if I really got the right firmware, is there a release-data in it somewhere?
A: unfortunatly not, you can use the release on this page to be safe: GenBoard/UnderDevelopment/FirmwareChanges - OK

I tried to use Mega-Tunix but it said something about not finding or detecting firmware. Does something have to be setup in my_make or somewhere else in the firmware?
Did you follow the steps on MegaTunix page ? (copy files from firmware/doc/megatunix to ~/.MegaTunix (files are in cvs head, not the nov24 version)).
After I copyed those files in to ~/.MegaTunix, MegaTunix "findes a error" and shots down when it trys to connect to the board (don't if the board is not connected).
Then I tryed to upload the newest firmware where I copyed the "megatunix-files" from, because I had version from before nov24, but the board dose not start up whit the new firmware.
Q: Should it work whit the old firmware, and is there a problem whit the newest firmware (got it with CVS)?
A: The firmware from CVS HEAD is not production ready. You should revert back to the nov24 version for road use. What is the error MegaTunix finds ? Does it detect firmware properly ? I hope you are using the latest cvs MegaTunix version, that might solve things for you, good luck; report. - DB
Re: Windows makes an "error report", I don't know if there is some thing i that, that can tell you what error it found..?
- If you need something to use right away while you work out your MegaTunix problems, MegaTune works just fine, and the instructions are at the bottom of the MegaTune page. I have tested MegaTune with the Nov24 build of the firmware with good results. What version of Windows are you using?
I'm working on putting Genboard onto my Golf 8v right now as well, email me or post a message sometime. -Where can I finde your mail-address? on my MembersPage/JimW

Hey I have a few questions I hope some one will take a few minutes at answer:
Q: Where and how to disable this self-learning thing..?
A: to disable VE learing: ve_learn_conf=00
Q: Where and how to adjust/disable closed-loop?
A: to disable ego correction, set ego_minrpm very high (above rev_limit value) ego_minrpm=60 -> 9600 rpm

Q: From which cars can I take ignitioncoils for dummy ignition, don't they have to have a "turns ratio" on about 100:1? Any links to places i Europe that sells suitable coils?
This is one advantage of DummyIgnition: almost any that is used for electronic injection. Turns ratio over > 99 is OK. 120 .. 200 seems to be the standard for electronic ignition. The reason is so that max voltage over the IGBT is lower.
If (sparkplug_threshold_voltage / turns_ratio) > IGBT_clamping_voltage (which is appr. 360..420V) than the IGBT will clamp => no spark (and not good anyway).

I read a little about this OutputTrigger but have a few thing I would lige to get straight:
- no need to define WOT_OUTPUT_TPS_THRESHOLD in my_make - the OutputTrigger will just hijack the output (act_wot_channel) that is otherwise unused without WOT_OUTPUT_TPS_THRESHOLD.
- I set the output in config by: act_wot_channel=P259_0 - definitely. (don't forget the 1k..10k HW pullup resistor to 5V, otherwise output of P259 will always be 0V. Also a series cap >=100nF if using LM1815, so the LM1815 input goes below 0V)
- See GenBoard/MenuSystem for how to set these msp, msq and mst commands basically you just type it to the PS2 directly connected to the board, or type into serial after going to "Manual mode" by the "Man" command (case sensitive).
It works. Thanks Marcell - great!

Plans to test the board on my desk..
- for testing, set config.primary_trigger=FE (or FF) and trig the board with a normal even-type (=coil type) pulse signal (square) from my signal-generator, and make it work (possibly with dummyignition, but not sequential injection without camsync).
- OutputTrigger can easily make 36-1 signal (to be fed back to inputtrigger)

Something goes wrong when installing Perl and win32:serialport. A: I had some problems when downloading win32::api with PPM so i downloaded win32:api from: http://ppm.activestate.com/PPMPackages/zips/8xx-builds-only/Windows/Win32-API-0.41.zip, unzip and install instuctions are included in README. -Johan. Thanks a lot, that works.
