Engine Control Speed Limiter
Engine Control Speed Limiters are programmed into the ECU by the manufacturer. The ECU is programmed to calculate the speed via the output speed sensor and keeping the tyre size and diff ratio in the equation. The easiest way to up the limiter is to import an ECU from Europe or USA. They cost around R1000 so they are not expensive. Go to www.ebay.com for America and www.ebay.co.uk for Europe. The ones from Europe have the highest speed limiter.
