so not only does the eeprom contain the maps, but it also contains the run program?

that is how you can add functionality like closed loop lambda in the eeprom?

so on a p8, what is the hardware that they have that allows them to run anti-lag that l8 doesn't have? as i understand it, you would use the same pwm circuitry to open the (modified) iscv, and just change to different maps for the ignition or fuel?
