If you're looking for the easiest way to add power and torque to your BMW, a Turner Performance Chip is answer to your prayers. Dyno-tuned by BMW tuning legend Jim Conforti, these chips are designed to make the most of high-octane (91+) pump gas and boost mid-range torque and high-RPM horsepower. To make the most of these improvements, the rev limit is raised, and fuel and spark maps are fine-tuned to make your BMW perform better than it did when it left the factory. There is no downside to installing a Turner Performance Chip - each chip is designed to safely improve performance, while maintaining driveability and improving responsiveness. All chips are shipped with detailed instructions and are typically installed in an hour by an enthusiast with hand tools. Turner Motorsport and Jim Conforti have over 20 years of experience with making your BMW come alive with software tuning. Unlike eBay chips, Turner Performance Chips use extensively tested, carefully designed fuel & spark maps designed to get the most performance out of your BMW without risking engine damage or reducing driveability. Since 1995, Jim Conforti has been using his expertise to fine tune the BMW driving experience by finding more power and toque and improving throttle response. With over 10,000 units sold, it's no surprise that Jim Conforti is widely regarded as the leader in BMW chip tuning. Don't be fooled by imitators - your BMW deserves the best. BMW's M20 inline six has a well-deserved reputation for being bulletproof and easy to maintain. Jim Conforti leveraged those strengths to find additional power and torque, without risking engine damage. Wake up your M20 and see performance you never thought possible, all while maintaining the legendary reliability they are known for with a Turner Conforti Performance Chip. Horsepower Gain: +15 @ 5,000 RPM Torque Gain: +15 @ 5,000 RPM New Rev Limit: 6,900 RPM Installation instructions included. Turner is so confident you will be delighted by your new no-downside power, torque, and overall performance, that they offer a 30 day money back guarantee on this product, serviced by ECS Tuning.

This is a simple kit to make it easier for you when removing your AFM/MAF when using a MegaSquirt ECU. In many cases, the air temperature sensor is built into the MAF, so removing it will require you to install an IAT Sensor somewhere else in the inlet tubing. This kit gives you the bits you need to do that.

These used a different ECU design. Additionally, some European 325i models for the 1987 year used an ECU with a part number of 0 261 200 073 or 0 261 200 081; this ECU is not compatible with the stock wiring on these cars. Also, this MSPNP may not work with automatic transmissions on the E34 or E32 chassis, which rely on the fuel consumption signal for the transmission computer.
