Dinan Performance Engine Software Kit for BMW 550i 650i 750i and 750Li (DIY)
Performance Engine Software extracts additional power as well as improving drivabiltiy.
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.
Performance Engine Software extracts additional power as well as improving drivabiltiy. The software safely raises the rev-limiter by 200 rpm for manual and SMG transmissions and 100 rpm for automatics, enabling you to carry more road speed in each gear, as well as optimize shift points. The top speed governor has been removed, enabling the cars to reach their natural top speed. Revised EML tuning provides improved drivability by speeding up throttle response.
