Uprev Knock Listen Device
Hi guys,
Just about to make an Uprev knock listening device..
http://www.uprev.com/documentation/K...n%20Device.pdf
Just wondering whether I can just tap the wire from the ECU or have to link it directly to the knock sensor?
Anyone using this method?

ok, its in place now.. and i can hear the usual 'engine noise' like those $$ knock listeners, except that its got massive whining noise in the back ground. tried a few different grounding mounts for the -ve wire but doesnt seem to make any difference. anyone noticed this noise?
will go out for a drive soon and see how it sounds at high rev/under load..!

Yep, I made one too and it whines like crazy. I haven't tried tuning with it yet due to 1) the whine and 2) I didn't have anything but earbuds which don't block out enough outside noise to really listen in on the sensor output.
Does anyone use noise canceling headphones with this? While driving?
