maybe the ecu had been changed with a halfcut one....owh ok...but my friend bought a proton putra year 97 with MMC ecu and got speed cut because of japan regulation which is all production car must limit their speed to 180km/h...so i thought might be the same goes to sgti with MMC ecu,maybe proton has removed the speedcut...
btw emange is not compatible with siemens ecu.
