OK I ADmit i watched the slow and ricey a.k.a. fast and furious and i saw somthing that was alright in that movie which was the lap top controlling the nitrous in the green eclipse is there really something like that or some kind of software that you can use in your car ,while driving to monitor thiings like nitrous rpm etc if so where is it at!! i want one there cool

 

Depends on the car, I use Datamaster to record and playback runs, and I can see almost all the sensors and data I need with it.

the F.A.S.T. system and DFI have something like it.
