[Diy_efi] re: Problem with cam mounted optical trigger sensor

Ok, well I've all but given up. Saturday I was ready to give up and I may just do that and try find someone with the knowledge to fault find the problem.
  I've thought some more about what is going on. If the signal coming from the optical sensor is clean then the problem is at the sensor right? I mean if I have a dirty signal I should see it on the scope shouldn't I? The problem is still EMI related because changing the plug leads made such a difference.
  My thinking then is that the problem is assisted by the EMI but is in fact in the sensor. Possibly thermal expansion (as Jay mention to me earlier) is causing misalignment in the sender reciever or extending distance between just that little bit. In turn the EMI is enough to trigger a false falling edge inside the conditioning circuit. Possible? I don't know. But the signal is clean and the ecu rpm jumps all over the shop in spikes just like EMI causes, but the scope signal looks clean.
  Matt, I tried calling you a couple times. I sent you an email also. Would love to catch up if only for a chat about my issues. My no. is 0421912980

Anyone have the table showing the standard size Ford injectors and their
corresponding voltage offsets? (19#, 24#, 30#, 36#, 42#)

I thought I had it saved on my hard drive but for the life of me, I can't
find it.

I also had a link to it on the www.nilesedge... web site but that thing is
gone now.

I've been all over Google and several discussion groups "files sections" and
I can't find it.

Any help?
