Here is our ROM file. Let's create Total Ignition Map using Map Calculator function
Let's find the Base ignition and Knock correction map and open them
Now we are ready to open Map Calculator
Add opened maps to calculator
The last step is definition of calculator expression. We can use special links to map values ([x1] or [x] - for map #1, [x2] - for map #2 and [coeff] for special coefficient
This expression is good for tune base and knock correction maps
Using track bar we are change coefficient that serves as Advance Multiplier in Subaru active igntion management...
...and see Total ignition map for all possible advance values
The values of the axes correspond to the main map which are checked on map tool bar
We can view all included maps fitted to main map axes by selecting view type
Here we are choose main map
This button determines that this map will be changed by editing at Map Calculator
Now we are try to change result map. Select area and use hot key for increment values
Let's see changes at original map
Back to Map Calculator
Switch "Editing" flag on Knock Correction map and try to edit result map
Let's see changes at original map
Back to Map Calculator
We can save our Map Calculator as quick access template
Let's close Map Calculator, map windows and try to open Map Calculator using saved template
Map Calculator is created
