Monster Tuning Performance ECU Remaps
 From 2002 onwards, a Defender ECU can be directly remapped to give better performance and economy.  
 
Benefits of upgrading the ECU Map include:

• Increased horsepower
• Increased torque
• Better throttle response
• Smoother power delivery
• Improved fuel economy
• Safer overtaking

 
Pre 2002 TD5's can still be remapped but this involves removing the ECU and sending it to Monster in order for them to reprogram it in house.
