To be honest, I do not have an answer. I wonder if at least the first one is optical?Fred wrote:VR or Hall? What type of engine is this on again?

Re: my simple ECU
Very familiar (no pun intended) with the Mazda B3 and B5 engines, however all of the ones I thrashed the living shit out of had carbs. Take some photos of the physical parts showing the thing that actually drives the wires, IE, the slotted wheel, or hall vanes, or toothed wheel, etc.

Re: my simple ECU
I will go to a junk yard and take one distributor apart this weekend, I guess that would be a great learning experience.Fred wrote:Very familiar (no pun intended) with the Mazda B3 and B5 engines, however all of the ones I thrashed the living shit out of had carbs.

PS: first I would need to trace where these three wires actually go
Re: my simple ECU
LOL! Tracing the wires is usually my FIRST step, then hooking them up ;-)

Re: my simple ECU
Here you are. It's 1995 Aspire distributor on these pics (mine is 1996, they have converted from non-OBD2 to OBD2 so something could be different, but probably still in the same ballpark)Fred wrote:Take some photos of the physical parts showing the thing that actually drives the wires, IE, the slotted wheel, or hall vanes, or toothed wheel, etc.
Re: my simple ECU
If it is the same, your diagrams are totally wrong :-) Maybe you didn't have pullups on your inputs? Clearly only two signals, as well. That pattern is very easy to handle. Enjoy.

Actually, the large ring is probably the signal I am currently handling - it is the "XXXX___XXXX___XXXX___XXXX___" is not it?
What kind of sensor is that?
Re: my simple ECU
It's classic mazda/mitsi hall effect. The inner ring is usually different, though that matters little.

Re: my simple ECU
Sequential ignition is implemented - now I need to re-solder everything nicer.
