I have not heard of that at all. the PC5 is a piggyback system so it does not write anything directly to the ECU. As far as warranty goes they would have to prove whatever you added was directly related to whatever was damaged. Either way warranty is a pain through any manufacture. And unless someone else comes out with a tune for our supercharger there is no reason to have it sent out.I thought I have read somewhere once you hook a power commander up to it the ECU becomes unreadable to Kawi dealers. Is that true? Could you have your ecu sent away and have it tuned? Just wandering as far as like warranty although I’m sure once you put a supercharger on your warranty is void.
