Overview

The software removes the top speed governor, enabling the cars to attain their ''natural'' top speed; and the V8 will pull right to red-line in top gear! Changes to the throttle mapping help soften throttle tip-in for a sportier feel and improved modulation capabilities. The combination of Dinan's re-calibration of ignition timing, fuel delivery, and cam timing produces a maximum gain of 9 hp @ 6000 RPM and 8 lb-ft @ 6000 RPM. Peak horsepower is increased from 414 to 421 at 7900 RPM. 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. Not to mention, 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.
