Computer algorithms running behind the scenes while you’re driving a modern car affect all sorts of parameters, such as ignition timing, air/fuel ratio and turbocharging boost pressure. New car engineers typically set these parameters at the factory to meet product marketing targets such as power level, fuel economy and emissions, and that means new cars are rarely fully optimised for ultimate performance. read more →
Each car that leaves the production line of a factory is actually unique. Some will actually achieve up to 10bhp less or more than the standard specification shown on the model. Depending on how well the components are manufactured and put together, it can make the slightest difference. So rather than a manufacturer put every car through a unique assessment and get a bespoke timing map, they adopt a standard one map fits-all philosophy. read more →
If you’ve ever wanted to get the most out of what your car has to offer, then you may want to consider learning ECU tuning. It’s a fun way to learn how to “Remap” and program your own car to peak performance – and for car enthusiasts like you, it’s definitely a joy to learn.
Knowing how to tune a car’s ECU means you can:
• Fine-tune your car’s fuel economy, especially if you know at which speeds it spends much of its driving time;
• Get more horsepower out of your car’s build
• Make the engine more responsive to acceleration
• Smoothen your engine’s power delivery, so you don’t need to switch gears as often
• Save money on gas bills by improving fuel efficiency
All of these terms are used to describe the same thing. Modern car and van engines have an electronic management system that controls fueling. This system is run by the brain of the engine, the ECU (Engine Control Unit). When you put your foot down, the ECU decides how much fuel and air to mix, squirt into the cylinder and ignite. Diesel and petrol engines work a bit differently, but that isn’t really important right now. read more →
Engine chipping came about after the introduction of the ECU. Since the early 1990s, most engines have been controlled by an on-board computer, the engine control unit (ECU), which among other functions, defines the ignition timing, fueling and boost pressure for all given engine speeds and loads.ECU remapping lets us change the way the engine is controlled – and engine tuning gives you a more engaging drive.
TDi engine tuning is different from a Petrol Turbo remap. A turbo diesel remap for one car will be different from another. And petrol engine ECU remaps will be different again. read more →
