I can't get no KR. Most I see on my EZlink is 1 degree. But that is rare. What do I check to make sure everthing is working. What do I replace. I ordered a ESC module what else should I look for. I hit with a hammer to no avail still no knock but my casper KR gauge is telling me different. Thanks for your help.

There is a simple way to test the integrity of the knock sensor.

KOEO and at 2,000 RPMs, tap lightly on the top of the block adjacant to the knock sensor. Casper's knock sensor should trigger the first few LED lites. The harder you tap, the more lites that should lite up till the audible is triggered. We strongly suggest adding the audible to Casper's wonderful guage, cause you may not always be looking at the guage.

Its a good idea to also verify this data with a good scan tool .

I don't know if the scanmaster has a knock counter. But that does show up on the ezlink, but the knock retard frame never shows the computer pulling timing. Some thing is wrong and I can't find it. I need some idea's as where to look. I repalced the ESC module but that was not the fix. Please help. Thanks.

The knock count goes up but no timing retard shown on my ezlink. Ideas, ECM maybe, ESC no I repalced it with the same results. Wiring maybe but why would I get a knock count. Bad grounds, I don't know if that would cause it nothing else on the car seems to be affected.

I don't know maybe the scanmaster would show the knock retard. But the idle seems unaffected by hitting it with a hammer. I thought maybe you could tell if the engine stubled or something. Would you be able to tell if the ECM was pulling timing if you hit it with a hammmer?

no.

Why don't you replace your knock sensor? They are available from GM and cheap. Make sure it's torqued to 14 ft/lbs.
