BMW 123d Remap
M B JARVIE – REMAPPING GLASGOW SPECIALISTS
M B Jarvie Remapping Glasgow are specialists in the performance tuning of car engine management systems. Engine remapping can improve the efficiency of your car’s engine and yields increased engine power output, torque and fuel economy. Specialising in cars tuned for road use, we can provide an engine tuning solution to meet your requirements. Re-calibration of the engine management system’s parameters, improves drivability whilst maintaining your engine’s service life and reliability, without the need to make any physical modification to your vehicle. Unlock the full potential of your car’s engine. Read on to see what a BMW 123d remap can do for you.
Let’s Talk Numbers
The chances are, your vehicle has been down-tuned by the manufacturer. Manufacturers build in limitations to your vehicle’s engine management programme, ultimately restricting its performance. There are many reasons for this – namely as it is cheaper for a Manufacturer to make one engine and then fit it to several different vehicles. The engine’s power and performance output is altered depending on the engine management program (or software) installed, thus suiting different vehicle models. It should be noted that by applying remapped software to your vehicle’s engine computer, it won’t then be overworking, but simply operating at its existing true potential.
The figures below show the typical performance gains a BMW 123d remap will yield, transforming your vehicle.

Stage 1 Tuning Explained
You may familiar with the term Stage 1. During the first stage of tuning, the engine management system is modified or a free programmable external ECU is installed. This often generates a significant spike in power, while decreasing fuel consumption. The beauty of stage 1 tuning is, there is no requirement to alter your vehicles original equipment to accommodate the additional power & torque. This is because your engine has always been capable of safely outputting higher power & torque, just the manufacturer didn’t want it to. A stage 1 BMW 123d remap from M B Jarvie Ltd will allow you to get the most our of your vehicle.
Increased power and torque from a BMW 123d remap provides further benefits. As a result of increased power & torque, acceleration time also improved. Advancing the ignition timing produces reduced delay in throttle response, improving drivability and feel. This improvement is most noticeable when driving at lower speeds, or upon the application of power following braking.
Lower Fuel Consumption
Increased power and torque is one thing, but what will a BMW 123d remap do for your vehicle’s efficiency and economy? More good news! Our tuning engineers also focus on a number of parameters in the ECU software directly relating to fuel efficiency. Depending on your driving style and also the quality of fuel used, noticeably better fuel economy can be achieved.
The benefits of a BMW 123d remap don’t stop there. Further to improved acceleration and top speed, you’ll notice improved drivability and feel. Many tuners will tune the car at wide open throttle, meaning that the adjustments are made only at full load. However, this is not optimal as the vast majority of time you will not be driving at full throttle and, as such, will also not see the benefits of tuning. This is why at M B Jarvie Ltd we tune your car in a way such that you can feel more power and torque at lower throttle positions and rpm. This ensures the “Wow” effect will be present throughout the vehicles entire rev range, not just when your foot is on the floor.
Protecting the Clutch
Increased torque, as beneficial as it is, does put additional stress on some parts, most notably the clutch. A build up of torque can result in clutch slip. To prevent this, our tuning setup employs a gradual rise in applied torque, which ensures that the clutch and gearbox (be it manual or automatic) is never under more stress than it can handle according to manufacturers’ specifications and recommendations. A gradual increase in torque facilitates a smoother driving experience.
Our Remapping Service
At M B Jarvie Ltd, whenever a vehicle enters our workshop for remapping we like to confirm a couple of things before giving it the green light for engine tuning. As part of our remapping service, every vehicle that enters our workshop will be taken on a road test to check for any drivability issues. Following a successful road test, the vehicle will then undergo a complete engine control unit scan to confirm engine management system health is good. If we note any issues that should be rectified prior to engine tuning, we will always contact you to advise & report. Learn more about remapping here.
