Ok, A8DK100F - the older roms do not have the 3D tables, incidentally.

Hi guys!
I've got address for Knock_Sensor_Calibration (A8DH200Z):

But i don't know adresses for:
Knock_threshold_weight_factor_RPM_Load_Cyl_1
Knock_threshold_weight_factor_RPM_Load_Cyl_2
Knock_threshold_weight_factor_RPM_Load_Cyl_3
Knock_threshold_weight_factor_RPM_Load_Cyl_4

According this: https://cobbtuning.zendesk.com/hc/en-us ... ed-Pistons
it is the main maps that need to be corrected.

See my post above - the older roms do not have those per cylinder 3D tables.

O, thanks! I missed this.
As a result, must I correct only the tables?:

Knock_threshold_filter_Final_Limit_Max_Cyl_1
Knock_threshold_filter_Final_Limit_Max_Cyl_2
Knock_threshold_filter_Final_Limit_Max_Cyl_3
Knock_threshold_filter_Final_Limit_Max_Cyl_1
Knock_Threshhold_Level_Final_Limit_Max

for "Knock Desensitizing For Engine With Forged Pistons" or the other tables?

td-d · **Posted:** Mon Feb 06, 2017 5:52 pm

I haven't used these tables - but from the COBB article it looks like the table to change is the weighting factor - in these older roms, there's only the one (that I posted below). Follow the same procedure, and don't forget to bump up the limit.
