​

 ➥ How long does remapping take?

Around 30-40 minutes (in some cases up to 2 hours).

​

 ➥ Do I need to visit you, or can it be done remotely?

Most stage 1 remaps can be done remotely (if you have an OBD cable and Windows laptop). We will carry out essential diagnostics using BMW dealer level diagnostics on all components of your vehicle. We will ask you to carry it out a visual check.

You are more than welcome to come in person. Though for some remaps you will need to to visit us (for some stage 2 and all stage 3 remaps).

​

  ➥ How long is the remap valid for?  

Remaps don’t have an expiry date, they don’t get outdated etc. The only way to erase/invalidate the remap - is to purposely erase it using specialised software.

​

➥ Do all remapping companies have the same remaps?

All remapping companies have their own secrets and remaps. Some adjust figures randomly without any testing, some download them from the web, some do testing and adjust parameters for every vehicle and then test the map again.

 A map is a binary file containing engine ECU setup.

So where do modified binary files come from? They are coded based on the stock (factory) remap, they are taken from the ECU of your vehicle or from the BMW dealership ECU database.

​

➥What does the process look like?

-We do a compulsory full vehicle diagnostic on all vehicles (free of charge) prior a remap using dealer level diagnostics.

- If there are no major errors  – we copy the current map (the binary file) from your system.

If there are major issues with your vehicle (e.g. faulty injectors) we will try to resolve them first or you can drive away to fix issues and come back when you are ready. We strongly advice not to do a remap if your BMW has major technical issues. They will stop your car from performing at it’s best. And as the car will be getting more power after a remap and will be driven more aggressively, it’s highly likely that combination of both will amplify the current issues and might make them worse.

-The next stage is to modify the map. A back up copy of your current map is saved.

-You will get a list of things that can be changed (some people opt in for more power, some prefer their vehicle to have better fuel consumption, some wish to remove EGR or DPF and keep the power as it is, you can pick things from the list).

-When the remap is adjusted as per your request, we upload it on your vehicle.
-The next stage is testing and running multiple diagnostics and tests to see how the vehicle is driving.

Then you go for a test drive, changes can be made as per your request.

​

➥Do you test you maps? Are they reliable?

 We only use maps created by our coder and the ones that were  previously tested and only specialise in BMW remapping. All our maps are created by our coder how has years of  experience in BMW remapping. The coder creates a map based on facts and figures and takes into account vehicles technical condition, age and your requests.

 

➥Will my vehicle be producing a lot of black smoke after a remap?

If your BMW wasn’t emitting black smoke prior the remap, it wouldn’t be emitting black smoke after a remap. Some low level remaps produces a lot of black smoke, we have an experienced and talented coder and maps that were tested on multiple vehicles. They don’t produce black smoke.

Please note: For stage 2 and 3 remaps little smoke is normal and there should be no black smoke for stage 1 remap.

 

➥Does fuel consumption change after a remap?

There will be very little to no change in fuel consumption if you are driving in town or at moderate speeds. But if you are driving your BMW in sport manner- then fuel consumption will slightly increase after a remap (comparing to the stock map). To get more power from the engine you need to add more fuel and more air, as a result fuel consumption might increase slightly. The more you put your right foot down -the higher the fuel consumption will be.

​

➥Do you remap gearboxes?

Yes, we do. Please contact us to get more information, as we have various packages available.

​

➥Can you do a remap and keep EGR and DPF?

Of course, there is no need to remove EGR or DPF if you are not planning to max the engine to its limits. For stage 1 remapping we would recommend keeping the DPF and mapping out the EGR (using coding and keeping hardware in place). This is the best combination for performance/reliability solution for BMW that is used for daily driving. If your vehicle is mainly for track use- we would recommend considering stage 2 remapping.

​

➥Is it dangerous/harmful to do a remap?

The more power engine is outputting the more strain there is on the engine. A good remap is just a code- so it can’t harm your vehicle even if vehicle is driven hard, there will be more wear and tear on the parts, but it will not damage the vehicle. Your driving style is what is likely to harm to the vehicle and cause excessive wear. A remap doesn’t put your foot all the way down on every traffic light stop you do, it’s the driver who does it.

​

➥Can the BMW dealership find out that vehicle was remapped?

If they are very keen on finding that out- they will, but in most cases BMW dealership will not look for signs of a remap and a remap shouldn’t affect your warranty (though it depends on what has happened to the vehicle and what it the reason for your visit to BMW service centre).

​

➥Does removing /coding out EGR increases power?

No, it doesn’t increase power, but coding out EGR increase throttle response and prevents DPF from clogging up and avoids engine from building up carbon (as exhaust gases no longer circulating inside of the engine).

​

➥Do swirl flaps or EGR needs removing?

The answer is no. There is no need to remove swirl flaps. Some M47 and M57 engines (prior year 2003) were notorious for swirl flaps failure. Most if not all M47 and M57 owners removed them a while back and chances that you still have them are quite low. Newer version (upgraded version -euro 4) of M57 engines came with redesigned swirl flaps and they are very reliable, and there were no known cases of one failing. Please note M57 engine 2.5 diesel doesn’t have swirl flaps.

EGR removal (hardware removal) on N47/57 engines and B47/57 engines will likely lead to head overheating. On some engines EGR is a part of turbo protection (Surge protection), hence we strongly advice not to remove any hardware on those engines and only disable EGR using coding. Swirl flaps on N47/57 engines and B47/57 engines can ONLY be removed if the EGR is coded out (it’s a fact and been tested by numerous people, please don’t experiment with your car). Otherwise your DPF (Diesel Particulate Filter) will fail very shorty.

​

➥Disabling EGR leads to DPF (Diesel Particulate Filter) blocking up faster?

No it wouldn’t. EGR is a main cause of carbon built up inside of an engine. Removing EGR (using coding) will significantly reduce amount of carbon in your exhaust (hence reducing load on DPF) and DPF will last longer.

Please note: Removing swirl flaps and not disabling EGR will lead do DPF blocking up and failing within short period of time.
