Question? I seem to hove somthin not right can some one look at my config at the bottom and see if it looks ok for triggering on this wheel.
Everything looks good to me except tooth_wheel_twidth1 should be 0x0A, for a 10 degree tooth width on the trigger wheel.
Hall
showing the tooth cut out of my Spica pump drive wheel
had 36 teth now I only have 35 left.
This is my 2nd proto
This is my first proto
I will remake it now and clean stuff up
VW COP
Too long for the 4cly
Looks like I can make it work for the V6
The pinout
if there is a power-NPN inside I think we will need to add a small NPN (2N3904), eg. on the IGBT pads:
- the small NPN's Base goes to where the gate was (1k away from ign259's output pin)
- Emitter need to go to a resistor (say 10..33 Ohm) then the COP pin 3 (driving the power-NPN's base)
- and the Collector goes to power (+14V, same that powers the coil)
Let me note that stepper driver could drive the NPN almost directly, through a resistor (and very fast!) if we allowed any digitalout()-pin for ignition in edis.c (not just the ign259 outputs).
1J0973724 might be the plug for the VW coil as vw etka lists them
Triggering
I have been working on a easy way to retrofit older cars with no tiggers.
The proposed GenBoard/InputTrigger setups below are optimized for fast startup (little time spent in cranking).
"They are not simpler than the supported (ncyl/2*N - m) missing tooth crankwheel setup (like a vanilla 24-1, 36-1 or 60-2),"
How is making a "Vanilla 24-1, 36-1 or 60-2" + some cam pickup(we need to know when to fire the coils and which cyl to inject to)
simpler the breaking off 2 tabs and adding a hall.
but with appropriate firmware support they can find out the engine position faster at cranking.
Anyway, I like the documentation format. We need to explain the direct ign setups on DummyIgnition page (or rather subpages) in a similar way:
- drawing - the 3D is especially nice (rotation direction is important in some cases!!)
- explanation
- advantages
- disadvantages
- config settings (if supported)
This is not the simplest for a 4 cyl.
It is not?? OK what is simpler that will do seq. injection and drive the 4 coils?
The pickups are 180° apart.
If the 2 pickups were ANDed it would look like a it had 4 tabs not 2
so with this we can see 8 edges one every 45° of the encoder or 90° crank
We can add more tabs if we want. 4 tabs would give 22.5° on the encoder and 45° on the crank.
With this we get:
- Sync after one gap.
- If a pickup dies we could still run.
- Very simple to make and install in a old distributor or on a CAM
- If the 90° is ok most Hall distributors could be retrofited by removing 2 tabs and adding a 2nd hall
This is a old example of a simple trigger for 6 cyl.
The pickups are 60° apart.
Pickup A is even. and pickup B is odd.
With this I can get sync after the first Gap.
So I will not have the crank and crank untill #1 comes around to get sync.
also if one fails I should be able to still get sync after no more the 2 gaps (1 gap past the working pickup) and use softwate timing for the missing pickup.
This can go ether on a cam or inside a distributor.

Yay I got it to GO!!!
2 things I found one was there was a port conflict on port A3
so I changed to
- define LED_STATUS 1
- define LEDPORT PORTD
now I get the pulses from the header JP1
the 2nd thing was that a reflash did not load etc/config.mtt
so I needed to
cat etc/config.mtt /dev/ttya
