Remapping a diesel engine gets you a more power, more economy it sounds too good to be true.
Many people often talk about their latest mods and power figures. Many of them go ahead and remapped their vehicle’s diesel engines and boast of more power, better economy and unchanged reliability.
Diesels have actually come so far in an actual short time. Back in the 1980’s they were related with being noisy, smelly and smoky. Now the Turbo diesel engine is a advanced beast and offers massive amounts of torque. We are seeing our associates swayed away from petrol due to the huge amounts of torque on offer from a well-tuned diesel engine. As engine technology has better-quality, the diesel revolution has begun. As soon as manufacturers started adding turbos to their engines we started to see huge power figures.
To further rub salt into the Petrol owners wounds the legendary diesel fuel economy has remained or in many cases improves after a remap. More BHP, oodles of Torque and better MPG. It almost seems to be too good to be true. The average power gains from a remap on a diesel engine are in the order of 30% more power. The costs vary from provider to provider.
How do engine remap work? The engine is controlled by computer. The computer determines how much fuel and air to push into the engine and controls the turbo and fueling to control this. Manufacturers need to make their cars reliable and meet the stringent emissions regulations. It is fair to say that there is a great deal of variation from one engine to the next so a general compromise is made when the computer is programmed. This compromise allows the car to run smoothly if it has been neglected or has substandard components through everyday wear and tear.

A remapping will change the computer settings and maximize the power made by the engine. In its simplest form it will raise the “safety” limits and force more fuel/air into the engine and alter the turbo spool up rates to give the maximum power gains. Many tuners will ramp up the fuel rail pressure earlier in the RPM range and inject the fuel slightly earlier but still keep peak pressure within the factory defined maximum limits giving a good mid-range power boost and improving the pick up under acceleration.(ref : TorqueCars )
After your ECU upgrade to your turbocharged diesel engine, you will enjoy:
• Increased horsepower
• Increased torque
• Better throttle response
• Smoother power delivery
• Improved fuel economy
• Safer overtaking
