2 Minute Overview

An increasingly popular method of electronic engine tuning, also known as chip tuning, chipping, or ECU Tuning, is the use of ECU Remapping. This allows you to increase the car’s power, engine performance, and driving comfort. Today we will explain what ECU Tuning is, its benefits, which cars can be chipped, and where it can be done safely. Source URL

Chipping used to be a term that referred to fiddling with your car’s electronic control unit (ECU), which was called “chipping”. This meant that you had to replace a factory microchip with a new one programmed by your supplier. The techniques for remapping have changed as remapping technology has advanced. Today’s enthusiasts can create their own ECU programs using readily available software and upload them via the Onboard Diagnostic Port (OBD). Although we don’t recommend this approach for a new car, as it can be very costly to get it wrong, it works well for tuner enthusiasts. Source URL

If you are new to car tuning (also known as chip tuning or remapping), it’s basically adjusting the settings of the ECU (Engine Control Unit), to improve parameters such as fuel efficiency, transmission, engine power, and overall performance. Source URL

ECU tuning or remapping is the best way to make your car more powerful. There are many ads that promise more speed, power, and less fuel consumption. It sounds simple enough. Source URL

You may be concerned about safety issues when you are considering electronic engine tuning. ECU remapping is safer than mechanical tuning. Source URL

Engine tuning is a way to increase the engine’s power. Many vehicle owners dream of improving their vehicle’s capabilities. They also want to explore possible solutions.

There are two options:

Mechanical tuning is expensive and risky. It requires mechanical interference in the car and the replacement of any components or engine.

Electronic tuning, also known as ECU Remapping, is an alternative. Source URL

ECU Remapping Process

Before you start ECU tuning, make sure you are familiar with how your car works. It is a recipe for disaster if you try to do something like ECU remapping without knowing the basics. Source URL

Can You DIY?

Yes, with the right tools. Anyone can access the ECU remapping software programs. However, remapping an ECU can be complicated and delicate. This is not something that anyone should do by themselves. Source URL

Learning from Online Guides

There are many guides online that explain how to remap the ECU best for vehicles. It’s a good idea to download one of these guides if you don’t have any experience in engine coding or programming. It can save you a lot of time and headaches down the line. Source URL

Risks of ECU Remapping

A bad remap can lead to strange, inconsistent behavior in your vehicle. You may end up having to take it to an ECU Remapping Center and pay to have it redone properly. The worst-case scenario is if your ECU is damaged by the software, causing total engine shutdown and you have to pay a few grand for a new ECU. Source URL

Test Your Remap and Cost

You can also pay to have your car tested on a rolling road so you can see how any ECU remapping has affected the engine’s power and torque output. This will cost you around £300 to get your car chipped and tested in this way. You can get the chip fitted at work or at home for a fee. Many engine tuning companies offer mobile services that will fit the chip at your home or work. Source URL

Improve Gas Mileage

You must also consider remapping your ECU, and giving the fuel injectors an ultrasonic bath. If you are sure you don’t want to die, it would be a good idea to swap the filter with your own, mount an electric thermal ventilator, and be sure to use the air conditioning unit. Source URL

Popular Vehicles to ECU Remap

Totyota Supra by Manhart

Manhart has upgraded the Supra to have more power, better handling, and some style points. The turbocharged 3.0-liter V6 engine under the hood produces 335 horsepower and 365 lb-ft of torque. However, the MHtronik powerbox, electronic control unit (ECU) remapping, and a new exhaust system are all part of the upgrade. The Supra is now capable of producing 440-450 horsepower and 479 lb/ft torque. Source URL

Lamborghini Gallardo

We notice the 3 kg (6.6 lbs) carbon fiber hood, Alcantara-wrapped carbon seats and Alcantar wrapped carbon seats, as well as a redesigned rear bumper, air tunnel, and side skirts and carbon door panels. RevoZport was able to increase 120 HP by remapping the ECU of the engine and installing a new exhaust system made from inconel (a nickel base alloy with chromium and iron), which weighs in at just 5 kg (11 lbs).
