Optical primary trigger page for MembersPage/EricN/Trigger

Planning on using 12-1 trigger wheel mounted in the distributer.

Trying an optical trigger now, followed instructions for Hall sensor on primary trigger as per manual. Seems to trigger properly.

Picked up an OPB804 optical switch. Built it into this little circuit that I found on the internet

Changed the 1k resister to 100ohm, voltage at led is 1.25v to gnd (normal for an infrared LED). Using pullup on vems

signal high (beam blocked) is 4.6V (good, since it goes higher than 2V)
low is .25V to gnd (good, since it goes under 0.6V)

Optical trigger no better, pc signal generater the same, fuel relay cutting out at any rpm, worse at low.

Traced trigger signal right to pin 29 on atmega128, signal looks identical on scope when compare to signal at the wire, suspect problem is in config, want to start with a clean config.

publish:

mcd dump (don't forget that in some cases it's necessary to reboot after trigger related changes had been saved! eg. to enable the trigger if it was disabled)
- [config], the reset thing I have been burned on before, but this problem has been ongoing since I built it, 6 months or so ago.
- we'll check primary_trigger (=01 expected for multitooth; don't apply advanced multitooth filter with =09 first)
  - Using coil type trigger temporarily, 6 teeth, this is all the signal generater (the one I was able to get working) could do and I have a 6 slot optical trigger wheel already made.
- secondary_trigger=02 (disabled for now)-Yes
- tooth_wheel=06 6 tooth
mct dump- [below the config]

after (Man)mdkffmdf01 .. let it run for some time while you apply trigger .. mdf00 (disables output) save the result (many "benchstat" numbers) and publish. We'll see if the relevant counters count.\n

I dont know how to interpret that but I can tell you the fuel pump relay cut out alot, I bet 10 times or more.
