November 2023

Introduction

This document provides descriptions of each of the data monitors available to view and log in the current Accesstuner software and V3 Accessport firmware. Not all monitors are available for all vehicles due to differences in vehicle hardware and/or engine control unit (ECU) capabilities. Some monitors are only available in the latest ECU version (strategy) for a given vehicle.

When conditions dictate that a change to the DAM is to occur, the current knock signal is referenced and the DAM is set to an initial value. If a knock event has occurred, the DAM will decrease. If there's no knock event, the DAM will increase (if no knock over a delay period). The DAM is reset to an initial value after an ECU reset or after a reflash. For the 02-05 WRX, the DAM ranges from 0 to 16 and its application to dynamic advance can be calculated as follows: dynamic advance map value * (DAM/16).

Feedback Knock Correction (Feedback Knock) -> This is a correction applied to dynamic advance based on knock. Feedback knock correction is the default correction of the three knock responses. When conditions dictate that changes to the dynamic advance multiplier or fine knock learning are not called for, feedback knock correction will be active (within specific RPM and load ranges). When a knock event occurs, feedback knock correction will decrease from its initial value of zero. The correction will be held until there's no knock event over a delay period after which the correction value will increase by a specific value (and the process repeats until the value ramps back to zero). If there is a knock event over the delay period, the value will decrease further.

Fine Knock Learning (Fine Knock Learn) -> This is a learned correction applied to dynamic advance. Fine knock learning is one of three knock responses. Its values are stored and applied based on specific load and RPM ranges. When conditions dictate that changes to fine knock learning are to occur, the current knock signal is referenced. If a knock event has occurred, the learned value in the current load/RPM cell will decrease. If no knock event has occurred over a delay period for that cell, the learned value will increase. Limits are placed on positive fine knock learning depending on the current dynamic advance multiplier (DAM).
