CEL Knock Sensor ShelGame Cal Questions

I am running Rob's Cal in my Omni and currently getting a CEL Light Flash WOT. I seriously think it is a false reading. I am picking up a new Knock Sensor today to try out.

I know about the headphone thing to test if it is knock but just wanted to get any opinions on Eliminating the sensor all together.

I am running a 2.2T2 setup with 25psi. I have ALL of the supporting mods including Spearco Intercooler,93 Octane, 3 Bar,40's yada yada and 7GPH Devils Own Meth Kit Spraying 100% at about 17psi. (The T2 intake is literally cold after a WOT run lol) I am running rich after the Meth kit was installed 10.5 A/F. I have to tune that. No indication of knock on the spark plugs either.

Any help would be appreciated. -Kyle

Check all your brackets. I had a bolt missing out of my PS bracket on the back causing it to rattle and set off the light at odd times.

What head and bottom end?

Have you logged the noise the motor makes and compared that to the knock threshold table? I would do that before proceeding further and I wouldn't eliminate the knock sensor.

I haven't logged the noise as I have no idea how to and I also haven't compared the knock sensor threshold table as Rob is the one who did my Cal. I am hoping it is just a bad sensor.

You can log it with a scanner or MPscan. You may want to contact Rob to see what if anything he did to the knock table.

I always raise the knock threshold for higher boost. But, I'm pretty conservative with it for obvious reasons. If it's truly false knock, it's easy enough to raise the threshold some more.

how easy? lol
