The problem is, once you do this, you run into problems... If you simply remove the EGR system from the car, but do not disable it in the vehicles ECU, you will likely run into many problems, such as:

  • Detonation.**
  • Poor running.
  • Lack of power.
  • Excessive temperature.
  • ECU Fault light on dash.

Evolution Chips can safely and correctly remove the EGR operation from your ECU, without the need for you to physically remove the valve itself so there are no tell tale signs that it has been done. (Assuming its in good order of course)

** The ECU often alters fuel and spark advance when it thinks EGR is active. If no EGR flow is possible because you removed it, you will have a lean condition which will be further aggravated by advanced timing, leading to detonation.

To see if we offer the service for your particular vehicle, just use the vehicle search function and it will be listed as an option in the results page if we can perform the work on your ECU calibration for you.
