I have some logs that I took. They show no knock period! But my wideband at WOT is saying ~14 to 1 :eek:

Can you or is there some sort of reset for the Innovate Wideband???
I can post a couple logs if need be...I mean I'm not exactly sure what I'm looking at honestly...

crap wrong section...Mods can you move this to the FI section please?

I don't see an AFR log on there...

I didn't see where I could log that. I will go back and have a look at the manual again this evening. I figured if I was that lean according to my A/F gauge surely there would be some sort of knock somewhere.

Not all knocks and pings can be detected by the stock knock sensor. Some sensors are very sensative and some aren't.

Did you free air calibrate the sensor. I made this mistake on a friends car. Didn't free air calibrate it and it was telling me he was running 20:1 under boost!!! Did the free air cal and HC reset per Sharif's instructions and its reading much more normal now.

I am assuming all that was done at CPRace. It was reading in the 11's and now over time it has just gone up in the 14s Surely running that lean at 8psi would cause some sort of knock that would be detected. I may need to give him a call and see what he says about it
