Just installed PFC need help

[SKYZER 33]

Hi

I have just installed PFC into my R33 gts-t what i want to know is the knock level

is not showing up on the commander any ideas as to why?

Thanks in advance

are you getting a reading of 0 knock all the time?

first place to have a look is at the wiring, in my GTR a previous owner had "fixed" engine light problems by wiring the ECU knock input to constant 0volt

It doesn't even say 0 it just has knock |

it doesn't read the knock level next to that as a number? You might need to turn on the "Peak Hold" function. I don't have a HC so I don't have instructions, maybe try a search for how to turn it on.

If it never goes over 0 then either the sensor is totally dead or its not connected properly.
