Is this the coolant temp bias were talking about. If it is, it's supposed to pull timing once it hits those temps. But to me it seems like it pulled timing no matter what. I had results by zero'ing out the coolant temp bias as well as the egr bias. I just about zero'd out most of the bias's. Now I'm not saying to do this as I have been told to be careful as the timing may not be retarded if it needs to. Just don't do too much at once and watch knock counts. HTH
