Can someone explaine how is it done? I know you connect your car ecu to a computer and change some files or smth?

I see many sites that can add extra 20 - 30 hp to a car by chipping it.... or reflashing ECU Whatever that means!:confused:

Is it bad on the engine or not? Anyone done it?

Normally not unless you use the gas pedal in excess of rpm range...

No its not bad at all, as long as you don't push it too far into the red as surk said.

Essentially what is done is there is a chip on your ecu board that contains fuel and timing maps, and from the factory they have to tune the car to be able to run in all sorts of conditions, and all sorts of fuels, however if you always use 91+ octane then you can advance the timing, and also enrich the fuel. etc...

The only thing is that you are stuck using 91+ octane while you are using that chip, otherwise using less than 91 you can damage your engine, due to detonation problems.

Just take some time to warm up the engine well before going into the red area...
