I posted this in the FA20DIT tuning thread, but figured I'd post it here as well.
Info for initial WOT run:
14 Forester XT (FA20DIT direct-injection 2.0L turbo w/ high-torque CVT)
Cobb Stage 1 91 Octane
93 Octane Fuel (New England)
S# 2nd "gear" (CVT) WOT to "redline"
Datalog: https://datazap.me/u/gathermewool/lo...2749&mark=1934

Info for highway cruise:
I just got back from a 2-hour drive with the AccessPort mounted and visible for the entire drive. At ~ -4 to 0 PSIG boost (cruising stead at 65-70 MPH with cruise control on) I was seeing upwards of -9deg feedback knock correction (FBKC = instantaneous correction) and up to -2.Xdeg of fine learned knock correction (FLKC = long-term learned correction). The dynamic advance multiplier (DAM) mostly stayed at 0.938 - 1.000, but fluctuated frequently lower, with a minimum DAM seen only once of 0.750.
I'll post the log up later today or tomorrow showing these cells, but suffice to say I'm concerned.
I'll be under the car sometime this week to search for something loose, like a heat shield, but would love to hear some other advice on this!
