The DINANTRONICS X is the newest installment of the highly successful Dinan foray into inline tuning modules. Like its predecessors it is a highly engineered piece of computer hardware and software that enhances engine performance to levels the stock programming is not allowed to venture. It does this without affecting long term reliability or the functionality of on-board diagnostic systems when run under recommended operating variables. Unlike its predecessor however, the DINANTRONICS X is Bluetooth smart and offers convenient access to the adjustment of power levels directly from the palm of your hand. A further advancement beyond its entry level little brother, the DINANTRONICS SPORT, X connects to additional inputs and/or has a more refined tuning strategy that yields more power as a result. For those that do not wish to (or can't) alter their stock ECU with a more robust engine flash the DINANTRONICS X is a perfect alternative to satiate the craving for "more". Whichever level of engine tuning is ultimately chosen you can be sure to be pleased by the result. The Dinan Difference is possible by employing a full staff of talented engineers that are well rounded in many facets of automotive engineering and backed by a wealth of hands-on knowledge. Stemming from diverse backgrounds not only on racing teams but on standard factory production line vehicles, we have seen it all. Manipulating these signals/maps with an adept hand, all the while keeping an engine running at its best and with the most reliable power, is what Dinan is all about. NOTE(S): (1) Please refer to the recommended mapping notice below for important operating information. (2) Fitment on the G11/G12 740i could be either D440-0131 or D440-0132. Please consult the connector images supplied and compare to your vehicle to determine which SKU is applicable to your specific vehicle.

RECOMMENDED MAPPING NOTICE


The DINANTRONICS X offers an array of different power levels (maps). These maps range from a bypass/stock setting at map 0 to a maximum power setting at map 7. The unit is shipped in map 5. This middle ground setting should be acceptable for all vehicle/engine configurations. However, you can adjust up or down as you see fit for your needs and/or modifications.


Please note however that for each map level we highly recommend the minimum fuel octane rating to run listed below. If you sense any unusual or unexpected behavior immediately turn down the map to a lower setting that did not exhibit the condition.
