Is there any way of telling what timing and duel maps the ecu is using at a give time? Fuel maps aren't that big a deal. The timing maps are what I am looking to figure out. EvoIX has 3 HI oct. and 3 LO oct. maps. What are the different tables that define what map is used?

JM8857-08 is using hi oct #2 when warm. I believe that #1 is warm up, #3 is with a fault code. This ECU also has a #4. To complicate it further it has dual boost solenoids with 7 duty tables and 4 boost target tables.
