High Knock Control - Please advise

Post by arnoldod »

I made some adjustments from Civic Turbo International CVT 2016, +6 psi high octane base calibration.

The adjustment that I did was:
  • WOT Lambda Adjustment low
    Air Temperature compensation
    MAP to determine WOT
    Rev Limits adjusted
    AFM
    TC maximum pressure ratio adjusted
    Torque setting
Everything ran fine and parameters within tolerance until the 3rd pull. Knock control raised to 97% (Cursor: 20:59) and knock count went up from 5 to 10 before the 3rd pull.

Attached is the calibration and datalog.

Appreciate your input.

Thanks

I would try raising the torque limit in case the ecu is try to limit power.

I would also try adding timing to the knock ignition limit… that would alter the knock retard… the closer the limit is to the egr table, the less it will retard

I'm afraid raising torque limit is not possible because I'm already at max torque limit of 250 nm for CVT.

What is the safety limit for us adding timing to the knock ignition limit?
