Think of it as a piggy back system. You have a switch box that holds two or three or however many chips you want for as many setting as you would like and then run it from there. you have a plug that plugs in where your old chip was and runs to the switch box with all the chips wired into the switch. I know you can do it with tbi and tpi so i imagine it wouldnt put that much of a load on the computer because you are only running one chip at a time. Im not saying i know more than anyone about chips but i dont see where it would put a bigger load on the computer. I would like to know where it would put a bigger load on the computer. As for the wiring it doesnt have to be a mile long. You could mount it close to the computer. When your at the track its not like your hood never opens unless you dont check your oil and all the other fluids before you run your truck. So mounting it under the hood would be no problem. It was just a thought though, hooking your laptop up to the truck isnt that hard either, its just like a big powerprogramer. What would be cool is if you could make a datalogger that you plug in for your runs at the strip, that way you dont have to take your computer down the track with you in order to log any data.
