I have a knocklink G4 light and on startup it goes from blue to green. I've never seen it go red which i'm presuming is good, but does this mean that all is working good and I have no-knock or is there a way to test it? I'm pretty sure i've wired it correctly and I have shielded the wires, also using a bosch donut 2 wire high res separate sensor. Just had another look and powered the car on but didn't start it, light flashes blue a couple of times and then green then stays green.
