I've got a 2017 with the Gen3 stage 2, running the Whipple Cal.
I live in BC, Canada which notoriously has pretty bad fuel. I run 94 octane rated Chevron. Because of this, I bought an nGauge to monitor things like knock etc.
On some 2nd and 3rd gear pulls, KNOCK is sustained at 3+, peaking at 5, which seems concerning to me.
I am new to datalogging, but it looks like the lambda is around 0.85 at WOT (which i understand to be normal). Timing (SPARK PID) was around 15 degrees (is this a corrected value after the knock sensors pull timing?). Vacuum at idle is 20inches.
Car runs smooth otherwise, idles OK.
Is 4-5 KNOCK something to be concerned about (as in do not drive the car hard)?
I can upload a datalog to look at... what PIDs should i record?
