I was so lazy and didn't read this installation myself. I also had it hooked up to the O2. After wiring the wideband the right way through ELD and simulated narrowband to O2, my A/F is jumpy now in closed loop like from 14,5 to 15,6 in no load. Like a waveform Is that normal?

Knock boards are tuned for a specific frequency for the engine that ecu was originally designed. For instance if you have an H22 and are using a knock board that was for a b16a it may register more noise than there actually is.

Knock Board resistor locations:

(All resistors are 100 Ohms - Brown ...

I got NA H22A and my knock reading is jumping to 1,7 V as well.
Even before I did anything to the base map or upgrade the engine.
No driving problems, I'll probably try and check it on the dyno wit the knock desabled.
