M5 and M6 Performance Software

The wait is over! Performance Engine Software is now available directly from your Dinan Authorized Dealer.

Dinan Engine Software for the E60 M5 and E63/64 M6 raises the factory rev-limiter by 150 rpm (8400 rpm maximum), endowing the V-10 with a broader power band and greater road speed potential in each gear. The software also removes the top speed governor, enabling the cars to attain their "natural" top speed; and the V-10s WILL pull right to red-line in top gear! The software also speeds up throttle response, providing a sportier feel and improved modulation capabilities. Dinan's software also provides re-calibration of the factory "torque limiting" programming, ensuring that maximum power is available under varying driving conditions.


The combination of Dinan's re-calibration of ignition timing and air/fuel ratios, along with a simple modification to the stock air filter elements, produces a maximum gain of 15 hp @ 8100 rpm and 15 lb-ft torque @ just 3000 rpm.


The software is easily downloaded directly through the factory port by your Authorized Dinan Dealer! There's no need to remove the computer and no "in-line" or "piggy back" device to accomplish the modifications. As you might expect, only Dinan loads the program in the same manner BMW intended. And with Dinan's matching new-car warranty coverage, there's no need to worry about hiding the software from your dealer or removing a device before taking your car in for service or repair for fear of affecting your warranty coverage. Performance without sacrifice!

A Stage 2 version of the software has also been developed in order to take full advantage of the additional air-flow produced by the High Flow Throttle Bodies, optimizing both performance and drivability.
