Knock Sensor Calibration, thresholds and noise filter

Why not just use my Alpha 32bitbase - all nicely coded in already?

That doesn't work either. Only knock sensor calibration comes up. But the address must be wrong because the table shows incorrect data

td-d · **Posted:** Thu Aug 27, 2015 9:25 pm

Two issues - you have a typo - adress as opposed to address - in all the tables; and the table names don't match the standard names in the Alpha 32bitbase.xml.

The tables have to be identical to what the 32bitbase names are.

Use these with the Alpha 32bitbase.xml, and they will show up. Spelling and syntax for the definitions must be identical to the base - else they won't show up.

Could someone define these for A8DH200V?

I followed the cobb guidelines after finding my tables ^^^ and sure enough the low rpm and load noise has reduced, knocksum increments not as frequent as with the original stock settings :idea:

I have had a look at this. Only problem is there is no 'Knock Threshold Weighting Factor' for my ecu.

Hi guys,

Would this be available for my 16 bit ROM A4SGD10C?

thanks,

Pascal

can you verified calibration?

Ah, didn't see the K, been dealing with so many A8DH roms recently.

I'll have a look for you.
