On the filter frequency what are you guys using as the starting and ending point? Mine is at 6 and 45. E85, lower and upper pulleys, e85, headers, etc. Noisy engine on acceleration.

I don't know what Jon has mine at but I also have a 16 and get a lot of false knock. They changed the sensors in 18 but they are not interchangeable

No different connectors.

Completely off? Knock sensor one and two? Or the two values for readings to zero instead of 6 and 45?

Understood. For pump e85 it is not as controlled as yours.

This is where people think they need 85% ethonal. My Buick makes 1300hp. With the v6. Has never ran anything but pump e85 NEVER TESTED.
My friend Jude has my old 426 with a whipple 3.0 pump e85 only just went 9.052 in late October Jon can attest to no problems

I would definitely NOT recommend turning off knock sensors in any situation.
Our Hellcat with zoomies still used the knock sensors when we were running the stock Hellcat PCM.
That data is still useful and there is no reason a street car should have the sensors disabled.
Some engines are louder and require desensitizing the knock sensors a small amount - but never off.

The Z06's we tune definitely require some finesse to get the knock sensors to work the way we want them but it can be done.
You could also disconnect your fuel gauge, remove your oil dipstick and delete other similar data supplying devices and your car will run fine. However, there is no need to do this and I just wouldn't recommend it.

I’m slow so it don’t matter.
