Comprehensive engine tuning.

The ability to tune your vehicle has never been easier then with software. In a matter of a few minutes your BMW can be transformed into a finely tuned European performance vehicle. Best of all, engine software or engine control units represent the most cost-effective means of achieving additional horsepower and torque. Your modern BMW is dominated by electronic controls. In order to extract maximum power out of the vehicle, it is essential to be able to control sensor inputs and calibrations from electronic signals. Dinan performance engine software is a true flash solution and integrates seamlessly into BMW’s ECU via an OBDII connection. This method allows full map rescaling and direct access and control over all of the engine parameters. This control results in smooth and effortless power delivery with drivability that can only be compared to BMW themselves; a compliment Dinan regularly receives in the automotive press.


The Dinan Difference is made possible by the features listed below which are common amongst all of Dinan’s software offerings.

  • Dyno tested to provide maximum horsepower and torque gains. Road tested to ensure real world results. In some cases over 130 HP and 110 lb-ft of torque gains are possible with supporting hardware.
  • The smoothest power delivery available on the market while still increasing turbo-boost pressure (if applicable), along with properly retuned fuel mixtures, ignition timing and full map rescaling for professional race quality performance. When needed water pumps and other systems are also tweaked to ensure the best possible durability and drivability for the vehicle.
  • Increased rev limiter enabling the the vehicle to carry more road speed in each gear which equates to a faster car.
  • Removal of the top speed governor, in most cases, so the car can achieve its natural top speed.
  • 50 state emissions legal. Dinan is the only BMW tuning company that can make that claim.
  • Matching BMW 4YR/50k new car warranty, including the possibility of consequential damages. A hallmark of Dinan that is unique to the brand because we stand behind our product with confidence.
  • Free software updates for the life of the vehicle.
