Hmm.. Now im paranoid, lol
What makes me think its chipped? .. well the story goes like this..
I asked to get a data stream done on my R32 by my current workshop/mechanic.
My workshop informed me that they could not do a datastream , because yje ECU was a nissan ECU, however its not an R32 ECU.
Upon further inspection, I found out its a stock standard R32 ECU.
when speaking to my workshop a few weeks later, and he informs me that the Datastream didnt work, possibly because the ECU may have been chipped in japan.
