Dinan Performance Engine Software for BMW M5 E60 M6 E63 M6 E64

SKU: D900-51M



Dinan Engine Software 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.

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 5 hp @ 8100 rpm and 5 lb-ft torque @ just 3000 rpm. Dinan’s software also provides re-calibration of the factory ”torque limiting” programming, ensuring that maximum power is available under varying driving conditions.


+ Raises Rev-limit to 8400RPM
+ Greater Road Speed In Each Gear
+ Removes Top Speed Governor

More Horsepower & Torque 
Add 5 horsepower at 8100 RPM and 5 lb-ft of torque at 3000 RPM.

Rev-Limiter Raised 
Safely take your V-10 to 8400 RPM. Add 150 RPM in each gear for greater road speed between shifts.

There is more to a tune than just adding power.  Power needs to come on smoothly and in a predictable way to make the car as fun to drive at wide open throttle as cruising around town.  It is your BMW, but reborn with new found acceleration and speed.

BMW Factory Matching Warranty (4year/50,000 mi)
No one offers better performance or backs it up with such a comprehensive warranty coverage.  Dinan matches the new car warranty coverage for up to 4 years or 50,000 miles, including the possibility of consequential damages.  If your BMW is past the new car warranty Dinan parts are covered for 2 years and unlimited miles.  See the Warranty tab for full details.

Top Speed Governor Removed
Dinan’s software removes the top speed governor so your BMW will be capable of achieving its true natural top speed.

A True Software Tune
The biggest benefit of a true software tune like Dinan’s Performance Software is that all of the communications between the engine sensors and the engine management computer (DME) remain unaltered.  This translates to properly returned fuel mixtures, ignition timing and full map rescaling to keep everything in sync.  Keeping an engine running at its best and with the most reliable power is what Dinan is all about.

Well Engineered
Properly returned fuel mixtures to the DME along with a correct tune means keeping the engine running cooler with less wasted fuel.  Ignition timing is a critical part of the equation to limit engine knock, one that many tuning companies ignore, Dinan Performance Software includes full map rescaling to protect the engine and keep everything running smoothly.

All BMW Engine Safeguards Retained
BMW worked hard to build systems to protect the engine incase of a failure, Dinan keeps all of these systems in place for the safest possible tune.

Emissions Legal
50 State Emissions Legal. See “Emission Status” for details.
