What does the ECU do?
The Engine Control Unit (ECU) is the ‘brain’ of the engine. Amongst other things it reads all of the engine’s sensor and makes decisions based on the accelerator pedal position, engine temperature and oxygen content in the burnt exhaust gases in your exhaust. Dependant on this data, it will control the correct quantity of fuel to provide a mix of fuel economy, performance and emission control.
ECU remapping is to first take a copy of the vehicle’s standard map and then to adjust its parameters within that map. As an example: fuel pressure, boost pressure of turbocharged engines and ignition advance and retard. When programmed correctly this process will unlock your engine’s true potential.
ECU programming will improve power and torque figures, increase throttle response and widen the power-band, resulting in a more flexible engine and a much sharper drive.
Another good benefit of remapping is a reduction in fuel consumption. Extra torque at the bottom of the rev range requires less throttle input on acceleration and when maintaining steady speeds. The vehicle can also be driven in a higher gear at slower speeds, thus reducing revs, and this also applies to driving when fully loaded, towing or driving through elevation changes
ECU Remapping is a safe process. It is just allowing the engine to perform as it can and should do without the compromises.
Car manufacturers sell vehicles across various markets that have extreme climates, different tax/emission regulations and diverse fuel quality. They have to take all these factors into consideration and therefore need to make substantial compromises in their tuning set-up. However, without facing such restrictions, we can safely optimise outputs unlocking your engine’s true potential.
· Improved fuel economy up to 15%
· Increased horsepower up to 35%
· Increased torque up to 30%
· Better throttle response
· Smoother power delivery
· Safer overtaking
A major benefit of remapping is a reduction in fuel consumption. By adjust the ECU’s profile to both widen the power-band and give extra torque at the bottom of the rev range which then requires less throttle input on acceleration and when maintaining steady speeds. The vehicle can also be driven in a higher gear at slower speeds, thus reducing revs, and this also applies to driving when fully loaded, towing or driving through elevation changes..
Hard cut limiter programs the ECU to cut the fuelling at a set RPM (normally 4300rpm) making the revs bounce off the limiter! This normally available on VAG Group, but we can consider other vehicles once we analyse the diagnostic data.
If a diesel engine starts easily and quickly when cold but struggles to start when hot, this is described as a hot start problemModern diesel engines are started by an ECU and not by the driver. The Pressing the accelerator pedal has no effect during a starting procedure. The starting is actually controlled by a ‘starting map’ in the ECU and is based on starter/engine speed/temperature and injected fuel quantity.
Generally, the ECU will not allow start fuel injection until the engine rpm is above a fixed map value.
Such problems can occur from low battery charge, engine coolant temperature sensor faults or the starter motor itself.
However, the problem may be the actual Hot Start Map within the ECU.
O2 Delete remaps are for those who have fitted either sports cats or de-cat pipes within their exhaust system and are subsequently having problems with the engine light being triggered due to emissions faults for error codes P0420 and P0430 (Cat efficiency). We can solve this problem by disabling these checks within the ECU map.
Launch control Software manages the amount of power to the wheels to ensure optimum traction is achieved.
From 2-4 MPH the RPM is limited to 2500-2750rpm. Once the pre-determined speed is reached the RPM Limiter will automatically move to normal RPM and from that point maximum power is allowed.
Many vehicles are programmed with a top speed limiter. Our speed limiter removal software allows the vehicle to reach its top speed. However, we are mindful of international road and highway laws and take the opportunity to stress our service is intended for track use only.
Many people do not like modern Start/Stop systems (which turns off the engine every time they stop), but it’s becoming increasingly common on new vehicles. Normally, there is a disable button, but this has to be reset every time the engine is restarted. With our Start/Stop Disable ECU remap, the function is disabled permanently.
Intake manifold flap failures are common on certain groups of cars and are expensive to replace. Our software can be used as part of a flap removal operation without causing fault codes or engine management lights.
EGR works by re circulating a portion of an engine’s exhaust gas back to the engine cylinders. This dilutes the O2 within the incoming air stream and provides gases, inert to combustion, to act as absorbents of combustion heat in order to reduce peak in-cylinder temperatures. NOx is produced in a narrow band of high cylinder temperatures and pressures.
However, the valves can become clogged with carbon deposits, causing them to fail or stick, thereby causing error codes and the vehicle to not run correctly. Our solution is a simple and effective method of improving the efficiency. By tuning the ECU you can disable the EGR valve, and results in lowered engine temperatures/improved throttle response and better economy. It can also increase engine life by reducing oil contamination and carbon deposits.
