The DINANTRONICS X is the latest in Dinan's successful line of inline tuning modules. This advanced piece of computer hardware and software enhances engine performance beyond the limits set by stock programming while maintaining long-term reliability and the functionality of on-board diagnostic systems when used under recommended operating conditions. Unlike its predecessor, the DINANTRONICS X is Bluetooth-enabled, allowing for convenient power level adjustments directly from your smartphone.


Building on the capabilities of the entry-level DINANTRONICS SPORT, the DINANTRONICS X connects to additional inputs and employs a more refined tuning strategy, resulting in greater power gains. For those who prefer not to or cannot modify their stock ECU with a more extensive engine flash, the DINANTRONICS X provides an excellent alternative to achieve enhanced performance. Regardless of the tuning level chosen, you can expect to be delighted with the results.
