The Stage 2 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, fuel delivery, and cam timing produce a maximum gain of 13 hp @ 8100 rpm and 8 lb-ft torque @ 8100 rpm.
- Raises Rev-limit to 8400RPM
- Greater Road Speed In Each Gear
- Removes Top Speed Governor
- Improved Throttle Mapping
- Improved Ignition Timing, Fuel Delivery, and Cam Timing
- 13 HP & 8 LB-FT of Torque when combined with the Dinan high flow throttle bodies
There is more to a tune than just cranking up the boost. 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.
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.
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 in case of a failure, Dinan keeps all of these systems in place for the safest possible tune.

After software is installed, the engine management computer (DME) needs to adapt to the new programing and takes about 100 miles to complete. Over the 100 miles the car will become faster and more responsive and so will your heartbeat.
Performance Software Stages & Upgrades
Any stage can be installed at any time and, if upgrading, just pay the price difference between the stage you currently have and the stage you are upgrading to.
