why use e manage ?why dont you get a propper ecu for it as your car is also not cheap .Original ecu with emanage somehow not much use unless you rechip your ecu .. auto learn will be disable when rechip then you need emanage
Original ECU have auto learn .why you want to tell the ecu to lean your fuel or add and when it reset to auto learn it will go back the same .
Rechip ecu yes you use piggy back original non rechip locally why need piggyback ?
Word of advise ,if you got the money get those rechip originally from factory not local .. not all local rechip is good and not all is bad too it is up to your luck to decide.
