Any problem with home filter set as high as 2
I have been having some starting problems for a while now. It turns out that a number of things were contributing to this. First I had my cas (E8 on FD) ground wired incorrectly causing the engine not to start while the starter was still engaged,but I got this issue fixed.
Now, lately my engine begun getting increasingly harder to start weather warm or cold. I have been messing with the maps(prime, battery, main fuel, coolant etc. for the past week, nothing made a difference. Today i started messing with the trigger and home settings and as I changed the home filter from 1 to 2 it started right up. To varify this was the problem, I again set it back to 1 and It took for ever to start.
I know trigger relates to spark and home relates to injectors.
Questions:
Is 2 too high a setting for the home filter? I notice most have their filters set to 1 .
Should I also set my trigger filter to 2 although I have no spark trigger issues?

Generally trigger and home aren't directly related to any one system (injectors or spark) but both.
The Trigger tells the ecu where the engine is in the firing cycle (think degrees of rotation from TDC)
The Home tells the ecu when the process starts all over again (essentially its back at TDC)
The only correct way to determine the filtration required is with a logging O-scope. Most don't have that capability so often it is set using only enough filtration to rid itself of any issues (like the ones you stated) If you no longer have issues then I would leave it where its at.
Also check the gap betweem your cas wheel and the outer most sensor (single tooth) and see if its within limits (FSM). That single tooth could have potentially been bent outward at some point.
