kr warning light??....
kr warning light??.... there has to be a way to make one... I saw a thread where somebody made one for a C4, so I figure f-body's and y-body's have very similar pcm's and there must be a way to tap an LED w/a resistor to a wire to light up when the knock sensor is triggered.... any ideaws?? 
Thats a cool idea. I wish it were as simple as attaching a light to the knock sensor, but the PCM filters the correct frequencies out of the knock sensors. I dont know if theres a dedicated output from the pcm for knock.

I believe a knock gauge does exist .. I've seen them used on grand prix's alot
myself... I use the EIO feature of my HP Tuners cable... I have a rule defined in HPT that if I get over 2* of KR it lights up an LED
I suppose if I used more outputs I could make it do like 1 LED for 1*, 2 for 2*, and 3 for 4*

I've seen the knock gauges for gnx's and stuff but dont have room for another gauge, would like just a couple led's hidden in an ac vent or on the a-pillar next to the wideband, if you come up w/any info let us know.... I dont have the eio, I got the old hptuners stuff...

though sounds like that won't do what you want?
