If you choose the exchange service, we will send you a Rebuilt ECU/DME from our stock.
Once you receive our rebuilt ECU/DME, then send back your defective ECU/DME core.
WHAT'S THE "CORE CHARGE" ?
The CORE CHARGE is a deposit that we collect to ensure that the exchange is completed. When we receive your ECU core at our office, we refund the core charge back to your credit card.
Your old ECU must be returned within 5 days of the delivered date in order to receive the refund of the core deposit . You may be subject to additional charges, in addition to a canceled warranty, if you do not return your old ECU within 5 days of receiving your new rebuilt ECU.
ECU's returned in NON-REBUILDABLE condition, such as HEAVY WATER DAMAGE, FIRE DAMAGE or PREVIOUSLY MANIPULATED ECU'S; may receive a partial refund, or no refund at all.
*FOR INTERNATIONAL SHIPMENTS ONLY* There is an additional $100 Core included in the shipping charges which count towards the core charge deposit. Once we receive the ECU core back, you will be refunded the original core charge plus the additional $100.

ECU/ DME Bad Common Symptoms:
The BMW Bosch computer was design and made in the 1980, at the time was breakthrough technology . As time goes by the computer and components will start to develop problems making it unreliable on its operation.
Our Rebuilding services covers the repair and preventive maintenance needed for the computer to operate at a 100% performance.
We have dedicated engine bench simulators and physical cars to guaranteed the repairs and to help with advise to correct problems with your engine electronics.

How to install the ECU
General Technical ECU Troubleshooting Guide
We have reverse engineered these Ecu’s and developed proprietary software along with equipment that allows us to Reprogram used Ecu’s to your car’s VIN Number and EWS Immobilizer system.
Because if you install a used ECU in a BMW starting from years 1995 and on, the Vin number and most important the Immobilizer Codes will not match. The non matching Immobilizer codes and different Vin number will not allow the car to Start. With a used ECU’s from a different car, the starter motor might work but as the immobilizer codes stored inside the ECU does not match the ones on your EWS security module there will be no OK signal for the ECU to start the engine.
Bmw’s have immobilizers modules called “EWS” which is a anti theft device feature unique to the BMW brand. The way the EWS works is by a code or “Rolling code” that changes every time the car is turned off. This unique safety feature makes it virtually impossible to swap used Ecu’s between BMW cars as the used Ecu’s will never match the EWS from your car.
Newer generation BMW’s carry the CAS module and smart key function, a newer version of the EWS system. More advanced than the previous EWS the principle of operation is basically the same were as you cannot install a used ECU from a different vehicle in your car.
An “EWS OFF” Ecu will have the security system feature deleted internally, that means that the ECU can be installed in a car without the need to Synchronize - Align the ECU to the EWS. Removing the EWS from the car simplifys the starting and running of the ECU and Engine. However NOT ALL BMW ECU’s can have these feature removed.
We have reverse engineered ECUs and developed many proprietary tools thru the years that allow us to perform programming operations even the dealership can’t. We can erase old coding along with programming of VIN numbers that are not possible even with the most advanced and expensive scanner tools.
“NO”. Our Outright Rebuilt Ecu’s will be programmed to your BMW’s VIN number and correct software that matches your vehicle. However, due to the fact the EWS system have a random “Rolling Code” we can’t guess what this random code is. Therefore, we RESET this feature to make the ECU able to be paired with your car’s EWS.
In order for the Outright Rebuilt ECU to work in your car, an ECU to EWS alignment - Synchronization has to be carried out. This operation is done using a BMW scanner that contains the feature of alignment - synchronization on its software “Note that not all BMW scanners can carry out this operation”. Here is a short list of most used scanner can carry out this procedure | GT1, Autologic, ISTA, INPA and others. The alignment - synchronization procedure takes less than 5 minutes to “MARRY” the Rebuilt Outright ECU to your cars EWS, once that is done the ECU will be ready to start the engine.
"NO". ECU reprogramming is not required because we will always make sure latest versions of software along with correct ECU to EWS matching is done in our laboratory.
Once we repair your unit , it will be 100% plug and play, already tested in one of our actual Tester vehicles.
