Piggyback aka si penipu .

- still gunapakai skrg. but limited funtion. - dipasang bersama ecu asal utk mengubah signal map/maf/hotwire etc hingga -+50% -ada juga yg bole edjust fuel bersama ignition sekali. -dan lagi advance funtion spt e-manage aem dll. -but still require to operate bersama factory ecu. -tap sini joint sana bypass sana why not go trus kpd standalone ecu. -price beza skit saja. -but all depends on yur budget and target. -remember. Tuning is the secret. -enjin yg ditune perfect walau guna piggiback system zaman perang jepun punya senang2 kasi asap enjin drag fully system yg tuningnya x cantik. ini pernah berlaku. -so find a good tuner.
