[basjoos] modded [via] the body of his ’92 Honda Civic – and managed to improve his fuel efficiency from 50-60MPG up to 95MPG for about $400. Even more interesting is the SuperMID (Translated) that he added to the car to monitor his fuel efficiency. It’s based on an ATMega8 that reads the CAN bus and displays realtime MPG information an a character LCD. The SuperMID is popular for Prius modders because the on-board display maxes out at a paultry 99MPG. If micro-controller’s aren’t your thing, [Atilla] put together his own CAN bus decoder and ported his code to a Zaurus SL-C700. He even added voice feedback notification for certain data events.
