Message: <blockquote data-quote="duh!" data-source="post: 1863227" data-attributes="member: 21559">Piggy back (not black) ecu is another aftermarket ecu riding controls on your original factory ecu. With some cars, they can work with either piggy back or standalone ecu (replacing totally your factory ecu) while others (like our RS200 5AT model) dont support standalone easily (as far as I am aware).Power FC is a standalone ecu, and perhaps, one of the cheapest options you can find in the market for full ecu. This means, not only this controls the A/F, it also controls everything else (blower, fan, aircon etc)The stock ecu is programmed for slight variations. However, when you modify your car, the ecu may have a problem understanding some parameters, therefore, causing lots of problems (misfire, bad fuel consumption etc, etc). Therefore, to make everyone happy, we can add piggy back to fool the stock ecu. Generally, people install these things to squeeze more power (& torque) out of the car and at the same time, if they are lucky, they will enjoy better fuel consumption. Most people end up not enjoying the fuel savings since when their car is a lot more responsive and feels more shiok, then tend to press the pedal harder... so... as the Chinese community here is Singapore say... LPPL (Lam pah pah lan).. hahahaha... .which means "back to square one"..I hope you get as much as I put it.... there are more qualified sifus here to answer your questions...... sifuus... anything to add??</blockquote>
