Frequently asked questions
The most common questions about the process, returning to original, warranty and heavy vehicles.
01Why ECU Exclusive?
We do not use ready-made files. We prepare the software specifically for the vehicle, taking its engine, mileage and installed equipment into account. We provide service and support in all 81 provinces of Turkey.
02How long does the procedure take?
On average 2–3 hours, depending on the vehicle’s condition and your requests.
03Can the procedure damage the vehicle during or after?
Software work is a programming procedure and needs no mechanical intervention. If the vehicle has no mechanical problem, no fault is expected during the procedure. Vehicles with mechanical problems are assessed first; for vehicles in a risky category we do not proceed until the risk is removed.
04Is the vehicle’s originality affected after the software?
No body panel, engine component or electronic part is changed, so the hardware stays original; only the software is updated.
05Is the vehicle taken apart during the procedure?
Newer vehicles are connected through the OBD connector and nothing is removed. For older vehicles without OBD access the ECU is taken out and connected to the computer by cable; the ECU is never opened.
06Do you provide support after the software?
Yes. We support you on every matter during and after the procedure.
07Can we go back to the original after the software?
For every procedure the vehicle’s original software is kept in our archive. You can return to the original if you wish.
08Does the vehicle warranty end if I have the software done?
If you take the vehicle to service with the modified software and have it worked on, you may lose warranty cover. Before service you can return to the original software at our dealers, use the warranty, then switch back.
09Factory software is engineered already, why yours?
Factory software is prepared by engineers too, but to suit the whole world it is written around averages of climate, altitude, fuel quality and driver habits. We prepare the software specifically for your vehicle, your fuel and the way you drive.
10Will a service centre notice the modified software?
With a detailed inspection it can be noticed. If you want to return to the original software before service, you can visit our dealers.
11Does a DPF solution cause problems?
Because a DPF can clog easily and is expensive to replace, a fault warning may put the vehicle into limp mode. Which solution suits your vehicle is decided after diagnosis, taking regulations and intended use into account.
12Do you work on speed limiters?
Yes. We can set the limit you want. The scope is clarified in a preliminary discussion according to the vehicle type and intended use.
13My vehicle shows a warning light, can you help?
Yes. We help you work out why the vehicle is warning you and which part is at fault. We are a phone call away.
14Is the software also available for buses, trucks and lorries?
Yes. In long-distance and load-carrying use, the effect on torque and fuel consumption can be more noticeable than on passenger cars. The engine works less hard on gradients.
15Can commercial vehicles be remapped?
Yes. Our work covers all passenger, commercial and heavy vehicles.
16How can consumption fall while the vehicle gains power?
The more torque a vehicle has, the less it struggles when pulling away, on gradients and under load, which is when most fuel is used. Because the vehicle pulls more easily after the software, consumption can improve with the right driving; the result depends on the vehicle and how it is used.
17Can automatic-gearbox vehicles be remapped?
Software can be applied to all vehicle models regardless of gearbox type.
