^ Already explained in this thread. A piggyback computer takes over some (but not all) of the functions the stock ECU performs to run the motor. Usually this includes fuel, timing and sometimes rev limit, etc. It is wired into the ECU, which must stay in the car to run all the other functions.

It was a great eight year run, but it was time to focus on other things. I'm still selling parts on eBay under micro*image seller ID and customers can still make requests for anything specific.
