Engine Performance Tuning

A performance tune is for drivers who want their vehicle to live up to its full potential and for those drivers who want to enhance their driving pleasure. At Essex-Remaps we pride ourselves on the  cutting edge research and development available to us, as this enables us to provide our customers with market-leading ECU remapping software for a performance tune which will make your car more pleasurable to drive, give you safer overtaking whilst also increasing acceleration, bhp and the torque that your engine is capable of providing by upto 35%.

Essex-Remaps understand the importance of reliable, quality ECU remapping.

All of our engine tuning software is developed in-house and custom-written for your vehicle. Our ECU remap files use data from Viezu’s Dynocom 3000bhp FWD rolling road combined with Bosch emissions testing equipment, all of which provides our customers with industry leading, insurance backed remaps from the only ISO 9001 accredited remapping company in the UK.  Regardless of whether your vehicle is petrol or diesel, or if it’s turbo-charged, supercharged or normally aspirated, we can optimise the maps held within your vehicle’s ECU to produce the perfect balance of smoother torque curve, enhanced bhp, a better throttle response and a smoother, more progressive power delivery, whilst not exceeding the safe parameters of the engine.

We know that vehicle owners are deferent, some will leave the vehicle stock just as it comes from the factory while others will add tuning items to try an d gain as much performance as possible from the car, adding these bolt-on items (performance air filters, high flow exhausts, bigger intercoolers etc) is great but you may not be gaining the maximum benefit without a remap, for example, adding  a performance air filter changes the amount of air flowing through the engine, which can also  change the air to fuel ratio. With an ECU remap, we will take your modifications into account, to gain the optimum benefits.

In general fuel economy will remain unaffected when remapped by Essex-Remaps, and, (depending on how you drive,) the improved atomisation of fuel, combined with increased airflow creates a more thermally efficient combustion – which can improve fuel economy.

Economy Tuning

The Very Best in Economy Tuning

Save fuel and money with Essex-Remaps BlueOptimize™ economy tuning services, available for most production cars, 4×4’s, motorhomes and vans.

The cost of fuel has been a bone of contention with most motorists for years now and it’s something that affects anyone who drives. Vehicle owners, from one car families to fleet operators have been looking for ways to reduce their motoring costs. Most car manufacturers now offer ultra-economical models, from Audi’s stop-start models to VW’s BlueMotion and Mercedes Blue Efficiency, all of which are a step in the right direction, but they still don’t offer better MPG.

– it seems blue has become the new green.

An Essex-Remaps BlueOptimize™ economy ecu tune delivers an improvement in mpg which, dependent on your driving style, can reduce fuel consumption by up to 20% whilst also reducing your carbon footprint, CO2 emissions, Smoke and HydroCarbon production.

Our technical department (Viezu) have developed this specific ECU mapping which, alongside reductions in fuel costs, provides an improved, sharper throttle response, improvements in bhp and torque and a smoother power delivery.

A common misconception is that you can’t improve the power of a vehicle and improve its economy but with years of research and development, we can and regularly do – Essex-Remaps have worked with many commercial drivers, fleet operators, private businesses and individuals to improve the mpg of their vehicles.

Benefits from a BlueOptimize™ ecu tune

  • Improved, low down torque
  • Smoother power delivery
  • Sharpened throttle response
  • Reduced turbo lag
  • Widened power band
  • Improved MPG and a noticeable stronger feel in the drive of your vehicle BlueOptimize™ is the latest and absolute pinnacle of environmentally aware tuning – We monitor all effects of tuning to make sure we are tuning without detriment to the environment. In recent tests on Diesel vehicles ( which are metered by the Opacity Smoke test at MOT time ) we have seen the following results post tuning.

Petrol vehicles can also have emissions reduced, although tested differently to diesels, petrol vehicles are tested for CO2 emissions at idle and fast idle and also for HydroCarbon emissions.

One example of reducing petrol emissions was performed on a Ferrari 458 which see results of HC emissions being reduced by a very impressive 85%
