Hi Fin, and all

Been?? pouring over the schematics etc. for ec-3 and em-3 that have been posted.
At the outset let me confess that I am a rank dyslexic beginner at reading (and understanding) schematics.

I have a ec-3 and em-3 which my records show that I purchased in April of 2010.
Reading through the documents, it seems like the only change he made with the?? 6/13/12??update??was to substitute a .001uf cap for existing at C28. Was the only change. For what reason was it done and is it suggested to make that modification.

I also noticed that he has an input lead pin 38 IC1 for a knock sensor.

Was there a software update between when I got mine and when he stopped shipping. Is it available and is it significantly important. Was the knock sensor included in that upgrade?


HELP!!!?? I'm learning just enough to become dangerous (mainly to my psyche) as I near the engine installation and testing (probably early next spring or with the weather we have been having--mid winter. (Chicago)

Any suggestions (other than to can the RMS (already installed)) to soothe my psyche?

Thanks again

Rich
