This is nothing new at all. Not even watching the video but it prolly talks about how you splice it into the iat and it then changes the voltage to the ecu making the ecu think that the temp is different than it actually is. This can cause excessive rich or lean issues and is not safe
However EPROM chips are a completely different story and are cheap and effective for the honda people but have to be soldered into the ecu. This doesn't exist for the protege iirc
Your right Tweety, but they actually dyno tested, and then sent the chip to ban electronic analyst, and it came back as a fraud, the splicing of wires does nothing because the way its "soldered" onto the board it doesn't connect to anything, its just made to look like its doing something, the only real wires that work is ground and 12v and that's just to work the led lol.
