Knock Sensor Circuit Design ... Tue, 22 July 2003 04:50 Go to previous message
Having read the following:

http://www.eng-tips.com/gviewthread.cfm/lev2/6/lev 3/35/pid/71/qid/54276

and also having a pretty good idea about the problems with generic plug-n-play knock detection systems, im a little concerned about jumping in and building something like the follwing:

http://www.gnttype.org/techarea/projects/knock/circuit.gif

my main concern (obviously) being how well tuned such a device would be for the specific harmonics of my particular engine (7M 83.5mm bore)

that said, i dont see many alternatives out there that would be any better (MSD included).

Does anyone have any thoughts on the application of the above design, or are there any resources available to help me build something better??

Or, am i just stuck with an imperfect solution, which ill just have to accept the shortcomings of?

cheers
