In Oz, the vehicle standards regulations are over 500 pages. You have to have an engineer's certificate after any modifications in order to re-register the vehicle. That also applies to changing the ICE for a different one, etc. Technically even changing the ECU program is verboten. But people still do it and plug in the old ECU to pass inspections.
