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:

You've defined an number of tables but not closed off those table elements with either a / or </table>.

nxm08240 · **Joined:** Wed Mar 21, 2012 10:45 pm **Posts:** 69

I've done that, Now it opens. The log shows that it recognizes the tables in the A8DH202X xml. But nothing shows up under the Knock Sensor category?
