I had some questions about the possibility of piggybacking my sirion m300. I’ve heard some stories about the possibility that the ecu will nog accept the piggyback or rewrites itself after a couple of days. I just want to be sure that this kind of stuff won’t happen so does anyone have some experience or knowledge if piggybacking is the way to go?
I know a standalone ECU is the way to go but I’m only trying to piggyback so to get more (s)miles per liter (atm 1liter per 15-16km). Since I drive around 40k a year I would be able to get my money’s worth out of it within a year.
I hope someone could tell me more thanks in advance
