Since the flash tune program's inception in 1996, the one requirement was that the tune needed to be installed at a Dinan authorized dealer. This forced those in the international market or those in rural areas away from our core markets to either send in their DME for a bench flash or to simply live without Dinan tuning. No one should miss out on the chance to experience a Dinan tuned BMW so for those not near an authorized Dinan dealer a solution to tune your BMW is finally available in an easy to use DIY package. Complete with the various interface cabling that is needed for the vehicle the kit enables the end-user to be able to flash their own vehicle in the comfort of their own garage. The kit will also allow the user to flash the vehicle between stock and Dinan at a moment's notice whenever the need may arise.
1. When ordering please ensure you have your VIN ready for the checkout process. It is crucial that it is typed in accurately and completely at that time. While we offer the DIY kits in Stage 1 form the additional stages will need to be purchased and installed at an authorized dealer as they require hard parts to function properly.
2. DIY software is at your own risk. Dinan is not responsible for any expenses incurred due to a failed flash. Please be aware of reccommendations for programming as referenced on page 8 of the installation manual (linked below) for optimum success. The programming cable does not have a recovery service and will require ISTA or similar BMW dealer tools in the event the ECU needs to be recovered.
The Dinan Team made a blistering fast software upgrade, using our years of experience tuning BMWs for the street as well as winning back-to-back Grand-AM DP Championships and the 2011 24 Hours of Daytona.
Dinan Performance Software is so much more than just turning up the turbo boost. It is a fully re-tuned engine management program that maximizes power while keeping all the BMW factory safeguards in place. Protecting your BMW while giving the most performance is the definition of "Performance Without Sacrifice". Drivetrain and engine components are analyzed for strength then the program is tested on the dyno and in the real world for durability and drivability. Dinan matches the new car warranty coverage for up to 4 years or 50,000 miles including the possibility of consequential damages. The top speed governor is removed on Manual RWD vehicles only, enabling the BMW to achieve its full potential.
