hi does someone can help me to add some timing degrees on a stock f-150 ?

the actual timing delivered is the minimal timing the ecu calculates
spark_mbt table has at least 3 multipliers, lambse, act and ect
spark mbt is referenced to calculate tv pressure for the trans and for feedback idle spark
borderline knock has at least 5 multipliers, act ect functions, as well as ect and act multiplier tables. bap correction, egr multipliers, and lambse
the lug tables formerly known as the altitude and sealevel tables have at least 3 multipliers as well for act ect and lambse possible egr bap and lugging timers
if you have variable cam timing which im not sure if you do, you can have up to 4 different maps per camshaft
their is absolute clip scalars for max and min demanded spark as well
i typically dummy it down, null the lug tables and run mbt out of borderline knock and be sure you remove any ect adders for spark at low temps which is typical on stock calibrations
your borderline knock table is where you'll be doing the majority of your timing changes.Quote:

I'd do a search on some other forums there's a wealth of info on how to properly tune ignition timing tables out there.
