What is an engine reflash?
Reflashing or remapping an engine computer is essentially just the process of replacing the existing software in a vehicle controller with new software. Reflashing an ECM is an immensely powerful technique that allows the engine to be tuned in the same way that the factory calibration engineers perform the task.
What is ECU flashing in a car?
ECU flashing, also referred to as tuning, updates the software that runs your vehicle by changing or modifying the vehicle’s memory chip in the ECU. These changes can notably improve your engine performance by improving power, producing cleaner emissions and bettering fuel efficiency.
Do I have to flash my ECM?
Yes, a new ECM will have to flashed before you can even start your vehicle. The “flashing” or programming of the ECM will require your VIN number to the supplier, who should be updating the most current software for your specific vehicle.

Wait five minutes, and replace the fuse.
Why do I need to reflash my direct injection engine?
1. Carbon Buildup on Direct Injection Engines: Reflash programming can help stop carbon buildup on some vehicles. New software can reduce carbon deposits by reducing the exposure of the valves to conditions that cause buildup by adjusting valve and spark timing.
What kind of engines are involved in the VW scandal?
Two later generations of diesel four-cylinder engines, as well as a diesel V-6, are all involved in the emissions-cheating scandal. All but a select group of vehicles have approved fixes to reduce emissions. The fix took a few hours on our VW Jetta SportWagen TDI.
Are there any problems that can be solved by reflashing?
Also, some reflash TSBs require the installation of an updated oxygen sensor that the new reflash software is calibrated for. 3. Oil Consumption: If you have a customer complaining that they are adding oil often, the solution may be to reflash the ECM and not rebuild the engine.
