I'm seeing 4~5 degrees more WOT timing than the Extended Spark Advance vs RPM vs MAP table is populated with. I've looked at every table TC gives me access to and can not find what is adding the additional timing. I populated the entire table with 38* and the log showed 41* from 4200-5100 and 42* from 5100 to 6000. I even set Max Spark Advance to 38* under Constants -> Spark Paramaters. Still logged 42* No matter what values I put in the Extended table, I get 4~5* more. I sent TC an email to see if there is a table he left out like the AFR adder tables the truck cals have. Can anyone here help?
