: Weird timing issue

Setup:

Roller rocker stock block
Decked GTi-R head with 203psi compression across all cylinders
444cc + Z32 MAF
GTi-R T28 w/Front mount intercooler 11x30x2.5 - 2.25 in/out
Calum RT B14 ECU
Innovate LC-1

When at WOT and about 4600 rpm, the timing disrupts and will not show what should be from the timing map.

In the screenshots below is a log from a WOT 3rd gear run, and at 4600rpm the timing goes down to 3 degrees.

I must confess that the knock sensor is damaged and the ECU knows because its throwing all along code #34. I strongly believe this could be the cause, but I like to hear some thoughts.
