Matt Farah reviews the new BMW M4 modified with DINAN’s “S1” Package. With power, handling, and grip upgrades nicely complimenting each other, is the M4 made that much better than the stock car?
The DINANTRONICS Performance Tuner is designed to be emissions legal in 50 states. Plug-and-Play installation in two hours or less at any of the 180+ Dinan® Dealers. While firmware is loaded directly on the ECU the model specific software will need to be downloaded into the ECU by an authorized Dinan dealer after installation.
Dinan says that their DINANTRONICS Performance Tuner doesn’t negate or void your new car warranty coverage and they claim this is the only emissions legal aftermarket ECU on the market complete with an E.O number. The ultimate objective of this tuning kit was to provide the ability to control every signal entering and exiting the BMW factory Engine Control Unit.
