This is a full-replacement computer, which can be just swapped with stock computer and makes it possible to control high performance engine. Stock computer doesn't have to be traded in when purchasing this POWER FC, so you can keep it with you for the case of emergency.
The ROM in the POWER FC has specially programmed data, which offers maximum performance to each engine model. This sporty engine management system programmed by APEXi is not only reprogramming the ROM but also it uses controlling system which is much superior to genuine ECU.
Also POWER FC can be set to your own desired setting by just connecting hand-held controller called FC COMMANDER (sold separately). By reprogramming the each control MAP and data, POWER FC will evolve into the special computer that is programmed by you. Of course it's also easy to get back to original factory setting when needed.
Boost setting can be controlled by adding optional POWER FC BOOST CONTROL KIT together with the FC Commander.
