MAXD has engineered these "crackle" maps very differently from previous ones you may have seen running on Renault Clio's and Megane 225's.Instead of adding loads of extra fuel in like the rudimentary Renault maps, the MAXD ST180 crackle map uses very specific ignition settings and uses the fuel already in the combustion chamber. Furthermore, to prevent the map from popping and banging non stop it has been engineered to make the crackling sound between a specific midrange rpm. This enables you to drive through town normally without attracting unwanted attention and giving you control of when the car crackles.As for the sound, in our eyes its just right, adding to the excitment and enjoyment of the car. Giving you that WRC feel when you are out on a B road blast.
