Product Details

See below for a list of common cars and chassis that this chip would be used in.

A lot of times when building a racecar or doing an engine conversion the EWS-II system can get in the way, adding another layer of complexity to the job. Since racecars and engine conversions have been such a big part of our history, we developed a special chip to eliminate the EWS-II system from the Bosch silver 413 DME. This chip is perfect for someone who bought an EWS-II computer without realizing what the system requires. The chip will de-activate the EWS-II code inside the DME thereby allowing you to use it in a car that did not have EWS-II or on a racecar that has the EWS-II removed completely (EWS module and key). It also has all of the benefits of the "regular" Conforti Performance Chips - more horsepower and torque, increased rev limit (7000 rpm), top speed limiter removed, etc. In the past you would have had to buy a non-EWS DME. This chip saves you both time and money. Click here to learn more about EWS-II.

Turner Performance Chips provide the ultimate in performance advantage! Adding a performance chip to your BMW is the easiest and most cost effective way of increasing BMW power, torque, and performance with NO DOWNSIDES. Through years of BMW performance tuning, we are able to maximize power and torque gains for 91 octane fuel used in North America. By making changes in the ignition and fuel maps of the DME we are able to optimize performance with no side effects or compromises. Other changes will make your BMW smoother and more responsive than when it left the factory. Our chips have a lifetime warranty and a 30-day satisfaction guarantee. If for any reason you are not fully satisfied with the increase in power and overall drivability you can return the chip to Turner Motorsport for a full refund. Chips are supplied with detailed instructions and are installed in about an hour. See below for specific information that we may need from your BMW.

Important Note: This EWS-delete chip is not intended to bypass EWS-II or as a workaround for a problematic EWS-II system. With this chip, no EWS-II components can be in the car. In other words, you cannot use this chip to bypass the EWS-II on a 1995 M3 because the EWS is having problems. This chip is only for using that DME in a car that never had EWS-II to begin with.
