Did a log of my cold start this morning to get a better idea of the resonance. Noticed that the ignition timing during that time is -8 and then moves to +20 when the resonance goes away. I am now more than sure that this is related to heating the cat on cold start. Looking into the tables, I found a table that apparently is for Timing after start. The values in that table are negative and I assume they would modify global timing to be significantly retarded. You might want to reduce the negative number in those tables say from -15 to -5. I think that would solve the resonance, but would it negatively impact something else I don't know.

Also the temp vs maf is in g/s?
Do you have the link in romraider you mentioned....I've been searching their forums and only find older info.
