Overview

Stage 3 Engine Software is for use with the High Flow Throttle Bodies and Air Mass Meter/Intake Assemblies, ensuring optimum performance and drivability. 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. 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 21 hp @ 7500 rpm and 14 lb-ft torque @ 7500 rpm when combined with the Dinan high flow air mass meter and intake assemblies. Dinan's software also provides re-calibration of the factory ''torque-limiting'' programming, ensuring that maximum power is available under varying driving conditions. 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.
