2008 BMW 135i: Reflashing Is Yummy; DME Tune, Part II
May 22, 2009
Fortunately for us, our office is literally minutes away from DME Tune. Scott hooked up said Versace-class battery charger and a magic reflashing box to our longterm 2008 BMW 135i and we split for grub.
Over a bowl of steaming pho at the local Vietnamese joint, Scott described the company's tuning philosophy. In a nutshell, they have examined various aspects of the engine and settled on a few states of tune that they reckon provide meaningful power increases while maintaining healthy safety margins. And by employing a reflashing strategy, they have access to virtually every operational parameter of the engine which gives them full control over the changes they make.
He continued by explaining that our 135i is receiving his Stage 2 reflash. This is, apparently, one better than Stage 1. The price for either flash is $649.
More specifically, Stage 2 can be used on turbocharged N54 BMWs equipped with, at a minimum, the factory oil cooler. And our 135i has one. If you want to see if yours does, take a peek in the passenger side wheel well. If you see a heat exchanger lurking behind slots in the plastic liner, you just found the oil cooler.
When we returned to the car, the process was complete. We were back on the road minutes later and giving the spurs to our homely little German coupe.
We'll have driving impressions and performance test results for you shortly. So keep your ears on, fine IL blog readers.
