Knock sensors revisited

[wheming]

So that just is supported back to one of the bolts on the side of the head?
I'll have to see how best to adapt a braket with the Lengel upper plenum.
Thanks for the pic!

I'm starting to wonder how the tables and related cal constants are being manipulated.
It may be helpful to understand the true issue(s), whether it's a calibration problem or a knock light code problem so the effort avoids re-inventing the mouse trap.

For example, the following table has been reliably used on a T-II with a 'G' head, two-piece intake (with support bracket installed - it matters!!) and slider cam at 22 PSI.

RPM VOLTS
992 .350
1504 .630
2016 1.590
2528 3.310
3040 3.860
5984 4.000

Do you have any data for a 2.5 turbo running similar components and boost for comparison purposes?
Or would you be inclined to think these settings would add safety margin if the only difference was 2.5 vs 2.2?

The 2.5 peak combustion efficiency occurs at lower RPM and the delta knock table will need to reflect that.
Send me a PM with what your running for a cam, intake, turbo, head, compression, etc...
If I have a closely resembling cal, I'll pull the table for you.

I put those values into a cal on MP Tune to get a visual of the curve, looks like the noise ramps up quickly until 3k. Not sure what turbo you had but I know the stock turbo hits full song by that point.

Agreed and good point.
When the knock signal is free of outlying issues, the curve typically mimics the efficiency curve of the engine for obvious reasons.
The turbo was a T3/T4 hybrid with a modified Turbonetics/Chrysler turbine housing.
