Knock and Very High Spark Advance

[Vince13]

Car had been running strong all summer and now started to set off knock alarm when just slightly getting into it on the street. I hooked up the powerlogger to capture what was going on and the spark advance is off the charts. Here is a snapshot.

Anyone see this before?

You've got 3 trouble codes set!! Get them corrected.

Yes I saw that and have started researching them. They seem to be intermittent as the car idles these codes flash and then disappear. I am also seeing .1 for knock retard on the scanmaster which I had earlier and Bob had said it was noise coming from the fan relay. I will be going through the connectors related to these codes and will reseat my ecm connectors, chip, and check all my grounds.

thanks please keep the ideas coming.

Your data is corrupted. Remove the powerlogger, clean the edge connector again, and reinstall. Your advance is not really that high.

Problem is solved, removed powerlogger and cleaned edge connector and ecm connections.
Thanks Eric!!
