You probably already know the term, but it's called a "piggy-back" system. It uses the stock ECU and an aftermarket communication box talks to it. Various sensors (WB02, knock, intake temp, exhaust temp) are used in tandem with the stock ECU and sent to that box. That box reads all the data and helps the ecu controls fuel, air, etc. to the engine. The Gameboy itself is actually your interface to that box so that you can monitor what it's seeing, and make adjustments to fuel maps and what not. It has it's cute little digital boost gauge, and other stuff. It's not terrible, it's definitely better than nothing, but to go further it really needs a more powerful complete stand alone system.
Then I can control AFRs, spark/ignition, injector load (opening and closing time), launch control, adjust rev limit, customize and auto-tune my AF maps. All that jazz.
