Remapping can be a potential minefield, please take time to read this section thoroughly for your own benefit. It is long but worth it. Please call us with any questions you may have.
Crest has been offering true quality software upgrades both on - site and on a mobile basis longer than the majority other tuning firms. Our maps are mostly developed in house, or by the best engineers in the business on our behalf as required, they and not simply purchased "ready to plug and play" from a software "supermarket" as many other tuners tend to.
OVERVIEW
We offer both on-track custom "live" mapping (the ultimate form of mapping, please see more info further down this listing as well as separate listing further down the webpage) as well as the usual standard form of reprogramming commonly known as "remapping" or "chipping".
This section you are reading now deals with this latter form of standard remapping, again see separate section further down fro live mapping.
A well engineered remap will normally give you better economy AND more power. However, we can configure the maps to your choice to give more power than economy gains (as with most other companies) OR we can configure for more economy than power gains (eg. taxi cabs, vehicles used for long distance etc).
We can tailor our maps to give customised effects and benefits to your requirements (within the limits of physics of
course) in varying degrees including but not limited to :
- greater fuel economy (up to 8%)
- lower emissions
- more power and / or torque at higher or lower revs to suit you
- more response in certain conditions
- performance more suited to extreme environmental conditions ( very hot ot very cold countries)
- different types of throttle response
- sheer brute power / torque gains
- any combination of the above factors
Our Philosophy here is simple...
NO GAIN / POSITIVE EFFECT, NO CHARGE, NO QUESTIONS. ( Assuming the car is in proper working order in the first place of course).WE ARE MORE THAN HAPPY TO MAP YOUR CAR AT AN INDEPENDANT DYNO OF YOUR CHOICE SO YOU CAN SEE FIRST HAND "THE BEFORE AND AFTER" EFFECTS.
HOW WE DO IT
Benefits are gained by ‘ironing out’ the compromises that are purposefully engineered into the car’s management system programme by the manufacturer (to allow for all extreme variations of weather, petrol grade, general atmospheric conditions in different parts of the world, as well as to allow longer intervals between engine services), and further enhancing the fueling, ignition and other parameters, thus attaining genuine increases in smoothness,driveability, throttle response, power and torque. The engine's "flat spots" (usually two) that are purposefully engineered into the power curve at the factory (so as to pass emission and noise regulations at those particular RPM locations) are also eliminated.
As well as adjusting the usual fuel/air/ignition/boost parameters we also (where appropriate) remap the Vanos system (many tuners do not, or do not know how), the acceleration/ throttle transition maps, knock sensor parameters, remove the top speed limiter and quite a bit more. We can also tailor our software maps to suit most engine modifications such as intakes, sport cams, de-catalised exhaust systems etc without putting your car onto a dyno (see further note on dyno use below).
We offer the following options for the actual remap process:
1.
POST / COURIER: You send us your ECU and we return it mapped ready to plug -and - play, typical turnaround 3 - 5 days.
2.
VISIT US: come to our or our agents' premises, by appointment, typical turnaround 2-3hrs.
3.REMOTE C - FLASH: We send you a special cable to connect between your laptop and the car's OBD port, and we map your ECU remotely (email or Ethernet) and at your convenience.
4. MOBILE: we come to your location at a time to suit you, carry out the remap and wait for you to test drive before we leave.
SAFETY & BMW WARRANTY
The new software can easily be reverted back to the factory map at any time.
A remap is usually "invisible" to your BMW dealer.
This form of tuning is perfectly safe for your car’s engine as long as it is serviced regularly (we recommend at least every 7000 mls on high perf/spec vehicles) and uses the best grade fuel available.
LEVELS / STAGES OF REMAPPING
We offer three Options of remapping to suit varying budgets and requirements :
OPTION 1 - STANDARD REMAP FOR OEM. The most common and least expensive format, these maps have previously been specifically formulated on dyno and road for the specific vehicle model in question. We then convert the data as required to “fit” your particular version ECU/DME and upload the new programme. The prices and link to power gains at bottom of this page all refer to this Standard option remap.
OPTION 2 - TUNED OEM. This is similar to option 1 above, but with adjustments made to the programme to account for mild to medium engine tuning modifications such as de- cat pipes, intakes, sport cams etc. Depending on the car and modifications this format may sometimes cost between 10 – 20 % more than the Option 1 standard maps, but quite often it is the same price, please enquire if interested.
OPTION 3 - ON ROAD / TRACK EMULATED "LIVE" MAPPING. This is the ultimate and most effective form of mapping (in our and many top tuners' experience),and is employed by and for all high end and Professional Motorsport applications such as Rally, Formula 1, Indycar, high end custom builds, etc. Companies who regulary employ such live road mapping techniques include Mclaren, G - Power, Mossleman turbo, Bugatti etc.

IMPORTANT ! NOTES & MYTHBUSTING ( PLEASE READ!):
1.LIVE MAPPING
We do NOT offer the kind of "Live Mapping " service that involves only a laptop connected to your car's OBD port and taking a quick drive down the road, because
no such process is possible! DO NOT get duped..... Firstly an OBD port cannot transfer data at a fast enough rate for a live map, and the fact the tuner has to stop the car, remotely amend the programme and then re load it onto the ECU means it is no longer a live map. The ONLY way to correctly "live map " is as described in “Option 3 “ above.
2. POWER GAINS / CLAIMS
Have you noticed our stated power increases are generally less than claimed by many other companies? This is because we are telling THE TRUTH ! No BS no exaggerations. If you really could, for example remap an E46 M3 to achieve + 35 or so bhp then in all likeleyhood the car would not run correctly in the first place from the factory! Think about this for a moment...there is really only ONE perfect Stoimetric air/fuel ratio and by definition only ONE optimal fuel/ignition map for any car (all else being equal and whilst remaining within generally accepted limits of engine safety, longevety and reliability) so if all"chip tuners" are doing their job correctly how can one tuner claim, say 15 bhp more than another for exactly the same model vehicle? Oh...and also charge you 2 or 3 times the amount we do? Defies logic does it not ?
FUEL ECONOMY
In most cases, whichever type of remap option you choose, you will notice an increase in fuel economy during
normal driving, anything from 4 - 8%.
3.COSTS & WARRANTY
You may have noticed certain companies charge almost twice as much as we do (sometimes more) for Standard remaps (as described for remap Option 1 above). What is the justification for this? Are they offering twice the power or anything different to other companies? Of course not (see myth buster No 2 above), it is marketing and nothing else. Some of these companies claim they are more expensive because they offer a full waranty against engine damage as result of their remap; well three things to consider here :
a). ask them to provide you a copy of the policy and it's terms, chances are they will/can not. If they do, reading the small print usually reveals all they do is revert the ECU back to factory standard then simply administer the normal BMW waranty procedure on your behalf !
b).It would be almost
impossible to directly attribute any kind of engine damage to a remap, for a start only the remap originator himself can usually "read" the tuned file to see what changes have actually been made and if they would be relevant to a claim.
c). As long as the remap has been correctly configured and developed in the first place there is no risk whatsoever of engine damage, not least because of all the safety fields and cut - outs incorporated into all management systems.
4.BMW "M" CARS AND OTHER PERFORMANCE MODELS
Despite what others may tell you, it is not unusual to get a proportionally lower power gain from remapping a performance variant of a model ( eg BMW M models or Mercedes AMG models) than from a "normal" model, reason being that the manufacturers themselves will have already mapped the car more "aggressively" from the factory, thereby leaveing less margin for furthe increases. This is not always the case, but worth noting.
5.DYNOS
Like any good tuner Crest uses dynos for some development and other tuning work of course, but we use one of two completely
independent dyno companies so there is never any doubt of the results.
WE ARE ALSO MORE THAN HAPPY TO MAP YOUR CAR AT A DYNO LOCATION OF YOUR CHOICE SO YOU CAN SEE FIRST HAND "THE BEFORE AND AFTER" EFFECTS. NO GAIN NO FEE, SIMPLE AS THAT ( assuming no pre existing faults with the car of course that would affect matters).
6.DEALER REFLASHES AT SERVICE TIME
A dealer can ALWAYS overwrite an updated BMW factory map onto your ECU / DME (this is often part of the routine service schedule). If we have remapped your car then our map will be LOST if a dealer does this. It is NOT POSSIBLE to "embed " or "scramble" any remaps in such a way that the dealer cannot overwrite it. The answer is simple here ..ask the service manager discreetly NOT to download any new info onto your car ! If your car is more than 3 years old then chances are you already have the latest version BMW software so the dealer will not do a new downlaod anyway.
7.VANOS AND OTHER VARIABLE CAM TIMING SYSTEMS
As detailed previously, some cars benefit from adjustments to the variable cam timing settings and in allowing these settings to act beyond say 7000 rpm ( whereas most oem maps close off vanos action/progression at this point). However this is NOT the same effect as fitting sport cams with higher duration and lift, nor anywhere near it, as some tuners will claim! Vanos affects cam overlap timing parameters ONLY and not lift or duration,consequently these alterations normally affect smoothness and emissions more than absolute power gains.
Don't get duped on this point either !

Similar in principle to the renowned Racelogic system feature, allowing you to execute quicker standing starts, but controlled exclusively through the factory ECU without need for any other electronics or sensors.
With Launch Control you apply full throttle with the clutch depressed, but the engine holds at a pre set optimum rev point ( for example 4800 rpm on an E46 M3); you can then side step the clutch pedal as fast as you desire and the new programme will then feed power to the back wheels progressively so as to keep wheelspin at below 10%, generally considered to the optimum for the fastest possible take off.
This item is available seperately or in conjunction with a remap and / or other listed software upgrades, in which case the combined cost would be discounted.
Most BMW s built 2008 - onward have many of the factory options already "built in" to them, but the factory will only activate those features that you pay for when ordering the vehicle.
We can re program the cars ECU and modules to activate many of these "hidden" features, either on site, by mobile service to your location, or we can send you a remote C -Flash cable kit that allows you do do the conversions yourself at time and place to suit you.
Features that we can activate / de activate activate include the following, some of which even BMW do not offer:
-Removal Of Seat Belt Chimes
-Removal Of Seat Belt Warnings
-Windows up/down with key
-Windows up/down with comfort access (Comfort Access Required)
-Folding Mirrors with key
-Folding Mirrors with comfort access
-Unlock doors when engine is turned off (Single pull on door handle)
-Removal of CIC Accept Warning (faster boot up after removal)
-Activate DVDinMotion (Play Videos on the go and stopped)
-Removal of camera warnings (requires cameras)
-Add Fuel Stop Proposals
-Add signals in HUD
-Remove window safety feature (windows will not stop rolling if door is opened)
-Remove Amber Side Marker Lights in headlights (Euro look)
-Fogs on with High Beams (Fog Lights will not turn off when high beams or used)
-Fog Lights on when car is unlocked
-Open and "close" trunk with key and inside trunk release button (requires power lift-gate)
-Add Digital Speed in Center Cluster
-Auto stop feature off when car is turned on
-Auto Climate Control off when car is turned on
-Digital Number Display For Tire Pressure Monitor with Temperature
-Control Cameras at any speed
Price start at around £100.00 inc vat and depend on how many items you want to re code for at same time, and it is assumed that your factory OEM module etc coding is all up to date ( we can update at small extra cost if reqd), please contact us to discuss your requirements.
