Consider it abandoned for our project. I just found out that we have the
tools for ion sensing and that's my major focus right now. Well that and
finals.
If I was going to go with the acoustic method I would have had to setup a
lot of dry experiments and I wasn't ready to sit down, start the motor and
record what happens to the acoustics while I "unhook" a timing chain, or cut
fuel, etc. Too many issues to deal with. I still think it would be a fun
project to record the general frequency range of detonation and see if there
are any traights apparently obvious.
Thanks for the links to the ion sensing.
