ok, stupid question.... keep in mind i havent modified a computer controlled car since i had my 88 s-10, at which time moding the ecm was as simple as unplugging the flash chip and inserting another one from hypertech... i do understand that todays cars are re-flashed with a tuner that basically loads a program onto the cars computer that the computer uses to control the engine, trans, etc, etc, etc....

that said....

Question: what the hell is datalogging anyway and why is that important?:eyebulge:

i think i see, so it basically allows you to watch your computer work so you can see how the installed tune is operating, so problem can be isolated and improvements made? sounds cool to me:cool: the SCT seems to do more of that than the diablo from what i have read.... :worship X-Cal2 is what im thinking...
