I hear what you are saying, it just modifies an existing ignition source. So
for a bare bones rocco with cis. It really wont help at all. However with a
turbo it will delay it nicely. With using the KS system you get the added
security of its maps and knock sensing abuility, sorta like a fine tuning on
the ignition., but can modify them with the mega spark. One thing i am
wondering is how you go about tuning the megaspark. I guess i have to get of
my but and do some more reading on the mega spark. Awsome thanks for the
info....
