Special Note: This kit may not be compatible with your vehicle as BMW employed multiple connection methods during the year range in question. Before purchase please consult the installation instructions linked above to verify a K-LINE connection method is valid for your vehicle. If a round under hood connector is present this kit will NOT work for the vehicle.

K&N free flow air filter element recommended for optimum performance.

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, 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 Engine Software safely raises the rev-limit by 240 rpm, endowing your car with a broader power band and greater road speed in each gear. The software also removes the top speed governor, enabling the cars to attain their ''natural'' top speed. Reprogramming of the drive by wire throttle system speeds up throttle response, dramatically reducing the delayed response to throttle inputs exhibited with the stock programming.

*Dyno results when combined with a K&N free flow air filter (available at additional cost).
