rilek la.... simple illustration....
its simple, both wira and bmw are cars, why 1 costs soooo much and 1 is so affordable?
both has an engine, both has wheels and doors etc etc, both can get you around.... so what does bmw has that wira doesn't have?? i dont have to list out and everybody knows what are the differences... so when ppl want to buy a car, why some ppl buy wira and some buy bmw??
so when some1 looking for aftermarket ecu for their cars, it depends on how much they have and what they want, some have the budget and thats why they buy motec/haltech/Vpro -- of course some ppl really needs the additional function that comes with it. but there are still hardcore modders with limited budget who tune their cars with SAFC/E Manage etc etc....
so it all depends on the buyer, and it is stupid to compare 2 things from the different league....
like the malay saying "tepuk dada tanya selera".... it depends on how much $$$$$$$$ you have and what you want to buy..... some ppl really uses the additional features that comes with the additional $$$$$ but some just wants the name.....
hey, my car got F Con V Pro you know???? :)
