i see that you burn the eprom with the programmer
and use the printer port and what info does the eprom hold

but what does the blue box the s200 do?

does the eprom hold fuel and ignition curves
and the blue box hold vtec points and stuff or what??

if i get the romeditor do i need the data logger?
i am just wanting to make small changes to my gsr
so if i start with the stock map and then tweek it like just move the vtec point around or bump up timing does it require the data logger ?

i know that you have these add-ons for boost but is there a way to select diffrent tables for say a 12 v imput for nitrous solnoid
so when i hit the button i could go to a retarded ignition table and increase fuel?
