I recently installed a freshly rebuild turbo with a bigger compressor wheel, and took the car for a test drive. I'm getting a decent amount of knock in low RPM range with some throttle input. It's not enough to the point where it could be phantom knock, so I'm taking it as legitimate. Motor is built, fuel is e85, and the only thing I changed is the turbo. I don't believe I'm too aggressive on the timing and the AFR I'm reading shouldn't be too lean for e85 at that low of boost. The log is attached, let me know your thoughts.

Phantom knock, you should search before asking.. Under the ALS/knck tab in ECU config change your parameters from 1500rpm and 0% throttle position to about 3000 rpm and 30% throttle position, you have to think about it this way.. in your log your knock is off the charts but you A aren't in boost. B. There is very little throttle given. and C your load factor is nearly non existent.. so the knock that you sensor is registering isn't real.
