Dinan, the BMW tuner that features a full line of performance parts sold and installed by dealers, has just released a Performance Engine Software/Boost Upgrade for the all new BMW 135i. I’m sure most of the bimmer fans have heard of Dinan, but in case you are new to the BMW world, you can always check out their website: www.dinancars.com
Here is a summary of their BMW 135i Performance Engine Software:
The Dinan Performance Engine Software safely increases turbo-boost pressure from the stock 8.8 to 13.2 psi, along with properly retuned fuel mixtures, ignition timing and full map rescaling.The Dinan Performance Engine Software safely increases turbo-boost pressure from the stock 8.8 to 13.2 psi, along with properly retuned fuel mixtures, ignition timing and full map rescaling. In fact, over 2000 engine management functions have been recalibrated, offering substantial increases in power output while maintaining the civility and reliability expected of a Dinan performance product.
Remapped Water Pump Speeds. In an effort to more effectively control oil and water temperatures, the Dinan software actually increases water pump speeds as boost pressure increases.
Boost Pressure Control. Increased boost pressure exceeds the turbochargers’ design limitations at higher rpm, potentially shortening their lifespan. Dinan addresses this issue by tapering the boost gradually at higher engine speeds. This approach also addresses the fact that with increased boost at higher rpm the turbocharger temperatures would exceed the intercooler’s ability to cool the intake charge, resulting in a loss of power and compromising the long-term durability of the engine. The tapered boost keeps temperatures within the design limitations so as to optimize output and ensure engine reliability with the added boost pressure.
The results of Dinan’s tuning are nothing short of breathtaking, with the added boost and related recalibration producing maximum output of 384 horsepower at 5700 rpm and 421 lb-ft torque at 4300 rpm. All of this additional power is available from Dinan’s software alone, which is easily downloaded by your Authorized Dinan Dealer in about an hour.
