Hi Guys
Having a Renesis with a Knock Sensor already present and bolted to the housing I built up a Knock Sensor kit amplifier/filter ($20) produced by Silicon
Chip Magazine March 2007.
Still building so haven't used it yet but planned to have a visual indicator. Makes sense that perhaps the damage
is done before I can respond.
Cheers

Plugging along....
Uh, I may be reconsidering the knock sensor thing. Hmmmm? Don't really want to add that much more, I have enough to do and it may be more prudent to be way more mindful of
my other factors. I am boosted, but at a very low lever (3lbs worth of springs in the waste gate...ground adjustable by adding or removing springs). I was using 87 octane, now using 93. Also,
will be much more conscious of timing and mixture. Heck, there must only be a few failure modes left that I have not discovered, so maybe I am closer????

Kinda looking forward to tearing her open this weekend......(hmmm, how did Einstein define insanity????)

Chris, somewhere back in history when I was growing up, it would be said that you have cast iron fortitude, hang in there, flight is eminent. JohnD

Since I have had an issue with detonation, I am contemplating adding a knock sensor. What do y'all know about this addition. I do not believe Tracy's EM has
a provision for a reading, so, what might be a good route to take. The brief research I have done shows different frequencies , types etc. What would be correct for a rotary, both as to a sensor and something to notify me
in the cabin? Thanks. I am about to replace ALL my apex seals and soft parts and hopefully finally lick this issue....hopefully....did I mention hopefully...determinably...persistent ? (heck, I wasn't planning anything else this weekend <g>)
