plugs into your ecu to change the way the computer controls your car, search apex neo, greddy emanage, they might give you a better answer.

if you do build an engine thats not stock dont use these, chipping the ecu with something like hondata, crome, uberdata, and nepture is gonna be way better.

Piggy back computers only modify the VTEC output signal and the MAP input signal to trick the ECU into doing something else. Like said above, a tuned ECU is far superior.
