    Knock detection after Cam, DoD, Phase Limiter Installation - LT1 Camaro

    Hello there

    I'm actually working on a 2017 Camaro SS 6.2L with E92A ECU

    Engine is modded with BTR St2 cam, uprated valve springs and washers, long headers, DoD delete, cam phase limiter.

    I'll be fine with VE, Idle stuff etc...

    But I'm facing a weird KNOCK detection issue. I tried stock map, stock map -10?crk, fuel enrichment... Always the same problem : All cylinders are detecting knock as soon as I go WOT. (knock flag is ON, so I don't think that is a torque management problem)

    Is it a problem with knock detection window being disturbed by the BTR cam and different springs ?

    PS : car is running on E85 at the moment, that comforts me into false detections

    Have you adjusted SOI for the cam? What changes have you made to VVE and MAF? I don't see anything in the screenshot that shows you are monitoring injection timing in any way. You should also be monitoring Torque Management Advance, torque PIDs and all of the timing modifiers. Also, no tune, no log posted, you probably wont get much help here.

    VVE and Idle on these cars is not the same as Gen 3 and 4.
