Piggy back ECU upgrades are a fairly standard accessory these days to the humble common-rail turbo diesel. Recently released from SAFARI (the folks who brought us the most prolific and arguably the best snorkels for years), is the ARMAX ECU. Suiting all modern Toyota engines, the ARMAX ECU has three pre-calibrated maps, and works in sync with the factory ECU. You’ll get better throttle response, more power, more torque, and better fuel economy, plus it keeps a keen eye on all the sensors on the donk to ensure driveline reliability and safety.
