So far so good. I ran the car until it was warm then took it for a quick spin. It was sit running a little hot (at the "N" in normal) but there was no detonation. I'll have to take it out later to really run it hard and see what happens.
The old sensor that I took out had some blackening on it. It wasn't black, but the copper was darker coloured in some spots and was no longer as bright as the hex flats. It would not wipe off either. Don't know what that means though.
I hope this is it and I can turn my energy to tuning what I have, and my money to some more mods. I'm crossing my fingers...
