Injection retard vs detonation curve - hex address?

[arjunior45]

Hi guys,

I'm trying to locate the hex address for the "Injection retard vs detonation curve" in the Q4's map.
Does anyone has any clue?

Thanks

I don't have a clue but the workshop manual says two things:

1. 04-43 .... When the knock sensor signals the detonation, the control unit reduces the ignition advance up to a maximum of -6 deg in steps of -2 deg.

2. 04-117 .... Under these conditions the control unit increases the quantity of fuel and reduces the advance values calculated by the appropriate map....

The second statement indicates that fuel is increased first, but I am pretty sure it is the opposite way.

However, I would not fiddle with that algorithm. But with most others I would :)
