Dinan Product Description

Stage 2 (DINANTRONICS Performance Tuner in conjunction with Dinan intake and exhaust) Maximum Power: 520 HP, 560 lb-ft of torque. A gain of 14 HP and 13 lb-ft of torque over Stage 1.

The DINANTRONICS Performance Tuner is a highly engineered and sophisticated piece of computer hardware and software that enhances engine performance, without negating or voiding your new car warranty coverage and without affecting long term reliability or the functionality of on-board diagnostic systems. It is also the only tuning device emissions legal in all 50 states. The ultimate objective of developing this piece of technology was to provide the ability to control every signal entering and exiting the BMW factory Engine Control Unit. These items are unique to Dinan and together they embody the apex of performance engineering in a powerful, reliable, and warrantied package.

The DINANTRONICS Performance Tuner uniquely has the capability to adjust target Lambda, correct short term trim as well as ignition timing errors induced by raising boost pressure. This enables Dinan calibration engineers to optimize air/fuel mixture and ignition timing at elevated boost pressure throughout the entire gamut of engine RPM and engine load. Additionally, the ability to correct short term trim corrections (the difference between target and scheduled fuel mixture) remain within OEM specifications. This minimizes knock sensor activity, which in turn means smooth engine performance, catalyst protection and power increase, while this is also required to make the car emissions legal. Dinan engineers have worked for two years on the DINANTRONICS Performance Tuner in efforts to provide BMW enthusiasts with Performance without Sacrifice.

Perhaps best of all, the unit automatically detects which engine it is installed upon and loads the appropriate mapping. Effectively making a single unit compatible with an extremely wide range of applications making switching to a new vehicle, sharing with another, or selling the unit a breeze.

Note: This version of the DINANTRONICS Performance Tuner is ONLY compatible with vehicles equipped with a mechanical wastegate. Only a visual identification is 100% accurate. Please consult the wastegate identification guide HERE to accurately identify what is on the vehicle.
