Yes got my V3.2 board thx Marcell !!
Well looking at it evrything looks nice,
got the O2 sensor as tge EGT asswell now assembly time :)
Altough the first problem lights up searching the site:
Found a couple of schematics (GenBoard/Manual/InitialTesting/VerThree), with a partslayout on the board but the parts are numbered like U20 or d33 well I understand that but couldn't find a BOM list where the numbers are explained. Well gonne try anyway :)
The schematic has the values for given components - except for some cheats and convenience we maintain in CVS bin/categories.* as on GenBoard/ManuFacturing
Well thing starting to lighting up added a page MembersPage/Daihard/Assembling ...

Q: When i use 3 evenly spaced magnets at the cranck can i still use dwell control and sequential injection?
A: Yes, but you need to add a cam position sensor //Emil
Q: OK thx emil, car fitted with cam sensors standard.
What is the added benefit from having a multi-tooth wheel then? The multitooth wheel allows more precise and faster diagnostics, should anythink happen (ECU can realize faster and safer that something is wrong).
Cause it cant get easier then glueing on 3 magnets :) Just make sure they won't come off...

I think using 3 HALL magnets 1 fitted 80° before TDC and evenly spaced 120° from the first magnet in combination with the 24-1 theeth cam ref signal is a good way to start.
?: Using the 3theeth triggerwheel as secondary check signal?
The engine is fitted with 2 magnetic signal sensors(HALL) fitted in the dizzy attached and driven by the exhaust camshaft.
But what is the pulse-pattern ?
-> first has 3 evenly spaced theeth; second has 24 theeth sensor placed 180° opposite of the 3theeth sensor;(I'll post a picture this week)
24tooth gives cam position reference,3 tooth cilinder firing order.
I setup a page here [url]http://www.vems.hu/index.php?page=MembersPage%2FDaihard[/url] so with help of the board we should beable to have system up and running in 6months? :lol:
From the manual CB80 ignition timing is constant 10° crankdegrees before TDC firing order 123.
Firing is 240° cranck rotation after each other and 3-tooth wheel matches TDC of piston
At the cam we have a HALL signal (not HAL:)).
Any suggestions please?
ANSWERS AND SUGGESTIONS:
A 6-1 tooth CAM signal would be perfect.
Or 3 (evenly spaced) crankpulses and 1 campulse.

- one with 3thooth wheel.
- one with a 24 thooth wheel.
size, specs?
Electronic controlled throttle type;
3xDENSO 23250-87701-000 295cc/min,
Injector fuel pressure rating = 2,5bar (Manual)
Pump 80 litres/hour
Denso injectors 13.8 ohms
fitted on fuel rail with fuel regulator
- PortInjected/SequentialInjection would be nice,
note: it's not about when to start injecting, but rather when to end injection (although the injector pulsewidth makes the connection, of course)

Needs togo to Members/daihard/software page fighting getting it created :(

The Genboard is loaded with firmware when you recieve it,but then after assembling you need to program it with firmware wich is compatibel with you aplication.To do that you need to load the firmware into the genboard.
You need a couple of software programs to:
1 change settings in the firmware
2 compile the firmware into a genboard readable code
3 Load the new firmware into genboards memory.
But first install 'Perl' from http://www.activestate.com for windows.if perl not works with the serialport:
type in the dos box: ppm install win32-api
then download and install http://cpan.uwinnipeg.ca/cpan/authors/id/B/BB/BBIRTH/Win32-SerialPort-0.19.tar.gz
unzip in temp folder
and in a dos box enter
perl Makefile.PL [optional PORT]example [COM2] default is com1
perl test.pl
perl install.pl
close all com2 connections ie disconnect the genboard and close all terminal programs and connections.
Type install.pl in a DOS Box and files will be installed.
Type test.pl in the Dos box and the com port being tested.
Getting the latest stable firmware release.
Goto http://www.vems.hu/wiki/index.php?page=GenBoard%2FUnderDevelopment%2FFirmwareChanges for the latest stable release or try downloading it here.
http://www.vems.hu/files/Firmware/release/
If you need to complile it your self...else skip this part
download - > http://www.vems.hu/files/misc/GETFIRM.ZIP
and unzip it and dubbelclick GETFIRM1.bat pres enter when asked for a password. All firmware is downloaded into c:\firware by default, copy and paste it to C:\VEMS\Firmware.
Then do this this:
go to dos: cmd.exe
then: cd c:\vems\firmware
make clean [enter]
sh [enter]
make all [enter]
exit [enter]
And your firmware is compiled.
Editing your firmware.
Download Winavr at http://sourceforge.net/projects/winavr Download latest stable WINAVR package (18MB)and install
open it and find the file my_make In the firmware/doc directory
also the config and table files are in the c:\vems\firmware dir, and special files for sensor calibration and other files are in the INC and ETC directories.
Make sure you can connect to the genboard and communicate with it using a terminal program. http://bray.velenje.cx/avr/terminal
Uploading to the genboard
In your terminal program write 'Manmcbfemcb' and the genboard goes into boot mode disconnect the terminal freeing up COM2.
Now in the dos box in the firmware directory type cd \bin
type : prog.pl vems.hex -tw :COM2 19200 [enter]
And your firmware will be loaded into the genboard
