We Tune Motorbikes

The manufacturer develops a vehicle for the international market. In doing so, they have to consider various framework conditions such as national emission standards, regional differences in temperature, different types of fuel or specific categories of insurances in different countries. This means that an ex-works vehicle needs to be equipped for a wide range of different influencing factors. The adjustment of the above-mentioned parameters to one single target market can therefore be carried out only by ECU remapping.

When we remap a vehicle, especially when fuel saving is the priority we focus on improving the low-end torque in particular and widening the power-band as far as we can.

This increase in low-end torque will mean less throttle pedal input is required to maintain cruising speeds, when fully laden or when on a gradient. It will also mean that the vehicle will be more comfortable in higher gears at slower speeds as well as requiring fewer gear changes overall.

If you combine these factors with adjusting your driving style to make the most of the extra low-end torque you will see an improvement in fuel consumption. 

When a manufacturer develops a new engine they have to take into consideration all of the conditions it may be subjected to in all of the regions in which they intend to sell this model. This means instead of just optimising the ECU’s program or ‘map’ to deliver the best performance or the most fuel efficiency they have to make compromises to the map to take into account these potential differing operating conditions.

These could include sub-standard fuels, extremes in temperature and altitude, differing emission laws and even the possibility that the vehicle may not be serviced on a regular basis and in accordance with the manufacturer’s recommended instructions.
ECU remapping is taking a read from the ECU’s processing chip of the vehicle standard compromised map and adjusting various parameters within the map such as fuel pressure, boost pressure (on turbocharged applications) ignition advance and throttle pedal control amongst others to release the true performance from the engine.

It is a completely safe process as it is just giving the engine the performance it should have had in the first place before all the compromises were applied to the original programming. Every engine will have its own unique map and by adjusting this we can fine-tune the characteristics of the engine; unleashing more power and in many cases reducing fuel consumption too.

ECU programming will not only improve the engine’s power and torque figures it will also sharpen the throttle response and widen the power band. This will make the power delivery a lot more linear, which in turn will make the vehicle feel a lot livelier to drive and the engine more flexible. Frequently, the vehicle’s power output is restricted by the manufacturer for no other reason than to ensure that the vehicle fits into a class to suit fleet buyers. As a driving enthusiast, you do not need or want such restrictions placed upon your vehicle’s ECU and its performance therefore you can benefit from the hidden power and torque locked away within your engine management system.

The other main benefit of remapping will be a reduction in fuel consumption. With the extra torque especially at the bottom of the rev range, you will see fuel saving as it will require less throttle input to maintain motorway speeds, you can drive in a higher gear at a slower speed as well as helping significantly when fully laden, towing or on gradients and even in start-stop traffic.
