You can get more power and better fuel economy from your BMW by having our technology-savvy professionals implement either the ECU remapping or chip tuning process. The two procedures offer the same result, but remapping is applied to vehicles manufactured after 2000, while chip tuning is used on older models.
Chip tuning involves removing the Engine Control Unit (ECU) from your BMW and reading a memory chip known as an EMPROM (erasable programmable read-only memory) chip. The manufacturer of BMW has stored performance-governing values on this chip. However, these generic values set at the factory may not be the right ones for your particular driving conditions. Changing the values to meet your needs could easily enhance the power and performance of your BMW as a result. After the ECU is removed, the chip is also removed, and its data is accessed to read the original values. When appropriate, the chip is reprogrammed with values that are more likely to deliver the performance you want from your vehicle. The chip and ECU are then reinstalled, and you will have a better, more fuel-efficient driving experience.
Remapping provides the same level of performance improvements as chip tuning, but the procedure is a little simpler. For post-2000 BMW models, the chip in the ECU can be accessed through an OBD/OBDII port. No need to remove the ECU from the vehicle. All the alterations are accomplished electronically through the diagnostics capabilities of your modern BMW.
After either procedure, you will see more throttle responsiveness, better fuel economy, and a much smoother ride. Any alterations made to the performance values are well within the safety and reliability parameters established by BMW, so you can be assured that only beneficial changes have been made.
