    Spark dvance and Knock Retard Histogram help

    I switched to 3.218 and cannot get the Spark advance or Spark retard table to read past .08 g/s. It will fill in this entire row but thats it. Seems like its just something small I am missing. Can you guys shed some light please?

    Stupid question, but are you sure there isn't a scroll bar to scroll down to see higher airmasses?

    Make sure you are logging in your Channels all the parameters needed for the spark graphs. That will include spark advance and knock retard as well as Column = RPM and ROW will need to be changed to Cylinder airmass (found in Math>Pre-confihure) which means you need to add MAF AIrflow to your Channel. The other better alternative is to log Dynamic airflow and use a User defined Dynamic Cyylinder Airmass....
