BMW used two different engine harnesses, please confirm if you have type A or B before ordering. It’s sufficient to locate only one of the sensors because the plug type is always the same for both of them (pictured above in the second photo). Harness Type A - Third Photo/Harness Type B - Fourth Photo RaceChip is the largest chip tuning company in the world! Their products are made in Germany and rigorously tested on the Autobahn. RaceChip offers the next generation of performance tuning. It allows for up to 30% more Horsepower and 20% better Gas Mileage with a very simple installation process. Unlock the untapped performance of your BMW engine with peace of mind from RaceChip. S: 5 Tune Mappings +51 HP +70 lb-ft Torque Up to +15% MPG Includes everything you need for installation, down to the cable ties. RS: 6 Tune Mappings +63 HP +88 lb-ft Torque Up to +20% MPG Includes everything you need for installation, down to the cable ties. GTS: 7 Tune Mappings +77 HP +105 lb-ft Torque Up to +20% MPG Limited 2 year engine warranty Built in warm-up timer One time reprogramming if used on different vehicle Includes everything you need for installation, down to the cable ties. XLR Throttle Controller: RaceChip developed the new XLR to increase responsiveness on the road. Their innovative throttle tuning system lets you tune your engine’s reactions to your taste – choose from 7 separate stages (Eco+, Eco, Neutral, Sport, Sport+, Race, and Race+). Your engine’s performance isn’t affected by RaceChip XLR, but you can access it more immediately and directly. Experience significantly sharper responses for yourself – no waiting for the message to get through or frustrating “pauses for thought”. And the best thing: installation is simple and requires no specialist knowledge. Try it now! The Brainbox: The Brainbox is the nerve center of XLR and controls the processes needed to optimize throttle response. The Brainbox’s compact size (ca. 70 x 80 mm) allows it to be fitted easily in the footwell of your vehicle. As it is so flat, it does not restrict the driver’s legroom at all. It can be fixed almost anywhere in the footwell, for example in existing slots or vents. The Controller: The XLR Controller allows you to choose between 7 stages: Eco+, Eco, Neutral, Sport, Sport+, Race and Race+. Each stage sharpens your car’s throttle response a little more, until in Race+ it’s like a thoroughbred sports car. You can mount the Controller anywhere in the car so that it’s in the right place for how you want to use it. The size and design mean it fits right in with the rest of the interior and the other control elements.
