Well there was this silver civic oriel who was getting reflash and i was getting unichip, the unichip guy said this is first time m doing on new civic oriel plus it was brand new so i think it wont be problem doing reflash or unichip. You will find the same silver civic oriel on unichip FB with dyno graph and with cvt the car was fine wit no problem coz even in turbo civic cvt are working perfectly fine. I got the engine oil change before getting the unichip/reflash. You can contact the unichip guy on FB messenger or call him up, he can give better advice on R18. Also u need to order intake/header/downpipe/exhaust for more power/torque with unichip or reflash, a friends manual civic reborn civic with these mods is around 2-3 cars behind stock turbo civic.
