Friday, BMW tuner Dinan introduced a new stage 2 ECU software file for BMW's E60 series 535i. As previously mentioned HERE and HERE, RENNTECH has a good history with Dinan, and has served as Dinan's South-Florida sales and support center since 2006 (with Dinan's California headquarters serving as a RENNTECH sales and support center as well).

Stage 2 Performance Engine Software

Dinan is pleased to offer the same stunning increase in performance for the 535 as that achieved for the 335i. And as always, Dinan matches the new car warranty coverage for up to 4 years or 50,000 miles, including the possibility of consequential damages. No one offers better performance or backs it up with such comprehensive warranty coverage. Dinan's 535 Performance Software is 50 State Emissions Legal under California Air Resources Board Executive Order Number D-176-35. It’s legal, makes lots of power and as it has been for over a decade, Dinan covers any consequential damages. More power and peace of mind…exactly what you’re customers have come to expect from Dinan!

The Dinan Performance Engine Software safely increases turbo-boost pressure from the stock 8.8 to 13.0 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. 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!
