ECU Remapping: What You Need to Know

Every car enthusiast knows that there is no such thing as having too much power, and there are many people who spend thousands modifying their cars to squeeze a bit more power out of the engine. Recently however, ECU remapping has become very popular, as it is relatively cheap, and can deliver excellent results quickly. There are a few things that you should know.

ECU Remapping: What You Need to Know– Remapping is not effective on all cars. Naturally aspirated cars do not respond anywhere near as well as those that are turbo- or supercharged. Nearly all modern diesels can benefit from a remap, as can turbocharged petrol engines. This is because these cars offer more parameters that can be altered.

– A remap generally boosts torque more than horsepower, but this isn’t a bad thing. Torque is what gives you that shove in the back when you accelerate. You can expect to see up to a 30% increase, though it may well be less, and potentially more.

– Remapping counts as a modification and you’ll therefore need to notify your insurer when the change happens. If you don’t you may find that your policy is invalid in the event of a claim. It’s not worth taking the risk.

– It doesn’t take long to remap a car, as everything is done electronically. It can also quite easily be reversed should the need arise. It’s better to have a custom remap for your car rather than just a stock one, as you’ll get better results.

– Remapping will only increase performance to within the car’s capabilities, so you should have no reliability concerns, except that existing problems are likely to be highlighted. Never remap a car you know to have engine problems.

– Remapping is possible because manufacturers limit the performance of their vehicles to cope with low quality fuels, or very poor servicing. In most countries however, the fuel quality is fine, and you should always keep up with servicing.

– Although power is increased, higher torque means easier everyday driving. This often results in improved fuel economy, especially in diesels. You can often specify whether you want a remap focused on economy or performance.
