Internal daughterboard that replaces the factory chip. It has a USB output cable that installs a port outputting from your ECU case.

one more question, anybody running Deatschwerks Injectors? I plan on running these and just want to know if i have to start changing things since when i get my NIStune because its not the same company.

Also, I plan on around 350-400whp, but i wont get there overnight, so if i were to buy 850cc injectors, would the injector multiply keep the fuel/ign maps at stock values if i changed the MAF and Injectors, or would i have to go back and tune it?

"Not the same company"? Not sure what you mean by that. Using injectors larger than stock its always a good idea to start changing things...like....adding a larger fuel pump and fuel pressure regulator. If you have Nistune you can enter your new injector values in the software so it will run right. 850cc are okay.

i'll have to dig it up, but there is something in there about the "brand". i already have a walbro and a nismo FPR so im good there.

buddyworm i sent you an email.

when you change injectors, you have to change void blastoff time first.

The nistune has a very good option for change in the size : use the "change injector size" menu . Put your old injector size, your new injector size, press "apply". You are done. Same goes with changing the MAF, you just select your new MAF and you are done.

setting fuel is also quite simple, when void blastoff time is well tuned. Just set the AFR you want at a given point, and you are done. If injectors are correctly set, your real AFR will be the one you selected. You cant get it simpler.

i dont have one (no laptop), but i use a friend's to tune my CA. really nice stuff. I am really considering buying one though

my car runs about 250 HP, my friend is over 430HP.

If you alter your K constant properly you shouldn't have to touch any of the maps except for rescaling the TP axis (as stated above, nistune has a handy-dandy function that does this for you).

For tuning the MAF you once again alter the K (but leave the TP scale alone this time), and edit the VQ table for your MAF. Once again, Nistune can do this for you.

There are different manufacturers of injectors; Bosch, Delphi, Denso, etc. ...and I forget which but one of them has an oval plug and the others use a rectangle plug (like your nissan has). Besides that, brand shouldnt matter with Nistune, but impedence would.
