Car Engine Remapping

The amount of improvement in the engine’s performance depends on the type of car that is getting remapping done. Turbocharged cars get the best results. This is because more air is pumped in, unlike aspirated engines where there is necessity for tuning.

If the manufacturer offers versions of a car’s engine with higher power outputs, this is a good sign that the technicians will be able to increase the engine performance. When car owners have the most powerful version of an engine, there is less to work with but gains can still be made.

Usually, power is boosted at least ten percent on normal aspirated cars. Turbocharged owners can expect to see an engine power increase up to 20 percent. Diesels usually get the biggest increase of up to 30 percent. Most remapping shops will have a website with specific data per car model based on past results.

The cost of remapping is often offset by the improvement achieved in fuel economy. This is usually a side effect of boosting performance, especially on diesel turbo cars. However, many people go into a remapping shop just wanting a better fuel economy for their car, which can also be achieved with an ECU remapping.

Performance technology improvements can bring drivers a fuel economy saving up to seven percent on diesel models. There are also fuel economy improvements available on petrol cars. Some remapping centres specialise in efficiency and can give more fuel economy improvements. Efficiency improvements utilise ECU parameters that is similar to those found in eco-special car models offered by manufacturers.

There is only one possible roadblock to ECU remapping, and that is the insurance company or car manufacturer. Any change on the car requires the owner to tell the insurer. Premiums will most likely rise as a result. Remapping shops will tell people what insurance companies will look more favourably on when it comes to modified cars.

Car manufacturers knows about warranties. Some manufacturers say that they do not recommend any power enhancement changes because the vehicle warranty could be compromised or revoked on any parts failures related to the enhancements. Remapping companies combat this by working on a large number of vehicles under manufacturer warranty with very few disputes.

Many remapping companies will offer a back-up warranty to fill gaps in the manufacturer’s cover about remapping or chipping and their related parts. Professionals also say that, once installed, a remap is not often detected by staff in service centres. This makes warranty problems less likely.

Manufacturers also say that owners should not change their cars because of buffer zones in the products to make sure longevity. They claim that remapping will decrease the longevity by removing performance limitations.
