I really don't want to go ecu searching if i can just get the rtek 2.0 upgrade on my current N374 ecu. It is chipped and tuned by BORDER Racing in japan (might be a flook with a sticker on the panel). I just don't trust to use it with a piggy back AFC so if its possible to "redo" my N374 then a simple yes or no will be nice.

Thanks.
