Haha i also read the "hidden ecu" part, i bet it might be gold plated or something xD.
If this has 270bhp, this must be the most powerful N/A Honda D-series build ever. 230kmh could be done in that engine, but in that car, i doubt.. Anyway he has Integra DC5 cluster in it, so maybe the speedo got f'ed up, and 130kmh shows up as 230kmh, you never know
