Well Engineered
Plug-in tuning devices all have one thing in common, they send a modified signal to the factory ECU, telling it the boost pressure is below target values. This then causes the factory ECU to raise the boost pressure to what it thinks is the correct value. This modified boost pressure signal causes errors in fuel mixture and ignition timing. These errors can cause the on-board diagnostics systems to set faults, but they can also cause exceedingly high catalyst temperatures and a loss of power. In addition, when power is increased, exhaust gas temperature will increase as well and this must be countered with a slightly richer air/fuel mixture. 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.
Unmatched Warranty
Dinan's comprehensive warranty program, introduced in 1997, provides superior warranty coverage to that which you would find elsewhere. If your vehicle is currently covered by the vehicle manufacturer's new car limited warranty, Dinan® products are warranted for the remaining term of the vehicle manufacturer's new car limited warranty. The manufacturer's new car warranty is limited to 4 years or 50,000 miles (80,000 kilometers in Canada), commencing on the date of first retail sale or the date the vehicle is first placed in-service as a demonstrator or company vehicle, whichever is earlier. Dinan's warranties are transferable when ownership of the vehicle into which the Dinan products were originally installed is sold. BMW automobiles can now be performance-tuned without the associated concern of negatively affecting the new car warranty coverage.
Drivability
There is more to a tune than just cranking up the boost. Power needs to come on smoothly and in a predictable way to make the car as fun to drive at wide open throttle as cruising around town. It is your BMW, but reborn with new found acceleration and speed.
