RC51 various info & full Akrapovic info needed
As I wrote on my introduction post I'm currently looking for a SP-2.
Maybe I've found the right one, but as you for sure are more expert than me, I've got some questions.
First of all it has the full Akrapovic exhaust (the standard, not the high one) and the dealer says it has got a dedicated ECU.
Well... what does it mean?
Is that an ECU specifically made by Akrapovic for their exhaust system?
And if it's the case, is that like a piggy-back module, or does it completely replace the stock ECU?
