ECU (Engine) Remapping
Is remapping safe for my vehicle?
Our impact tuning process enhances and optimises the power of the engine within safe limits, not beyond them. The extra power will also result in fewer gear changes. Manufacturers have to build in a tolerance for the engine components, to manage the effect of wear and tear, production variations, and to ensure their warranty claims during their warranty period usually three years, are kept to a minimum.
Most race and rally engines are pushed for every last bhp, and thus they are more likely to fail, while regular car/van/lorry engines are limited back, well away from the probability of multiple failures. Each engine is different as in how much it can be pushed in a remap, but a good remap from a quality tuner will never get close the limits of component failure.
What exactly is remapping?
If you want to tune your diesel vehicle and still keep the vehicle’s safety and durability functions for the engine/transmission/ESP intact, the only way to tune a diesel vehicle is to make changes in the existing control system of the engine.
That is exactly what we offer with a remap. Our tuning process has total control over all parameters at any moment and doesn’t disturb the safety functions of the car by deceiving the system.
Apart from an obvious power, torque and fuel economy benefits you get the following advantages with a remap:
- Nothing needs to be connected to the vehicle after tuning to get the benefits
- No loose boxes and wiring flexes in the engine compartment
- Torque is adjusted/limited on lower gears (to avoid damage on the transmission)
- Boost pressure and air flow is optimised
- The original settings can be reinstalled if required
- On board computer shows correct fuel consumption
- Anti-skid program (ESP) function is fully retained
- Torque reduction when shifting gear (for comfort and durability) is retained
- Optimal regeneration (emptying) of diesel particle filter (DPF) is retained
We plug the world’s leading diagnostic system into your car to check for existing faults (if any), before downloading your current ECU software for backup and analysis. Your software is then re-written by our tuning experts to provide the new characteristics you will have discussed with your consultant, whether it is ultimate power, ultimate economy or a combination of the two.
Once the software has been re-written, it will be loaded back on to your ECU, and your vehicle will be tested. All original manufacturer’s data such as VIN number, serial numbers etc. are re-instated exactly as they were before the remap so the changes cannot be detected by any normal means of a diagnostic check from your dealer.
It is important to note that every single remap performed is unique. We do not use ‘standard maps’ that would limit the effectiveness of our tuning. The original software and data we download from your engine are instrumental in allowing us to work out your new map for you. Add-on boxes can never achieve this degree of tailoring for your vehicle or your requirements.
