Since the flash tune programs 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 moments notice whenever the need may arise.?
Note:?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 the stage 1 form (or stage 2 in this case), the additional stages will need to be purchased and installed at an authorized dealer as they require hard parts to function properly.?
Software Description:
Dinan Stage 2 Performance Engine Software safely increases turbo-boost pressure, along with properly retuned fuel mixtures, ignition timing and full map rescaling. Dinan?s software also removes the top speed governor so the BMW will be capable of achieving its natural top speed. Producing substantial increases in power output while maintaining the civility and reliability expected of a Dinan performance product. In an effort to more effectively control oil and water temperatures, the Dinan software actually increases water pump speeds as boost pressure increases. And as always, Dinan matches the new car warranty coverage for up to 4 years or 50,000 miles, including the possibility of consequential damages. No one offers better performance or backs it up with such comprehensive warranty coverage.
Increased boost pressure exceeds the turbochargers? design limitations at higher rpm, potentially shortening their lifespan. Dinan addresses this issue by tapering the boost gradually at higher engine speeds. This approach also addresses the fact that with increased boost at higher rpm the turbocharger temperatures would exceed the intercooler?s ability to cool the intake charge, resulting in a loss of power and compromising the long-term durability of the engine. The tapered boost along with the stock oil cooler keeps temperatures within the design limitations so as to optimize output and ensure engine reliability with the added boost pressure. When BMW creates a software update so do we. Dinan will make software available at no charge to keep your car running as well as it possibly can.
