Do the 32-bit ECUs use the same logic?
The 32-bit ECUs generally follow the outline as described above. Some of thresholds may be different and some conditions may not apply or there may be additional conditions not listed. There are also other elements to knock control with the 32-bit ECU which have not been fully analyzed. But the description for the 16-bit ECU is sufficient to tune for the 32-bit ECU. Q Whenever the IAM is re-evaluated, you said that the IAM is set to the value in the ‘Advance Multiplier (Initial)’ table, even without an ECU reset. I’ve never seen this in my logs. Can you explain why? When the IAM re-evaluation starts, IAM is always set to this initial value, however this would be almost impossible to catch on a log because the next chunk of code is involved in decreasing/increasing the IAM (with an intial IAM step value of 4). This happens pretty much instantly as far as logging is concerned and it would be very unlikely that you would capture it.
