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)
