No, this does not involve any change in the ECU... as this Tomica NSX-R, as you know, has no engine. Rather, there are many paint chips marring the otherwise good off-white paint. The mesh wheels are from the HW 934.5 I modified earlier. And just like the Porsche, this is a WIP.
But this car’s fate is still unclear. Should it be repainted, or should it wear the patina with pride?
