I reflashed my 2005 987S Boxster yesterday, using the standard flash from
Softronic, and everything went beautifully. Cable arrived promptly, I uploaded my stock file in a matter of a few minutes, and three hours later there's the tuned file in my email. A few more minutes of downloading the tuned file into the car's ECU and I'm taking my test drive! The mid-range power (say 3500 to 6000 rpm) is noticeably stronger; the very high end is harder to tell. The car gets up to speed more quickly and is stronger in the middle passing gears especially. I'm not a drag racer, so didn't do a lot to ascertain the change in "0-60" that everyone likes to talk up. On a road coarse, I'm betting that better middle and upper mid-range results in lower lap times.
The benefits of being able to flash back to stock at any time, and not having to remove and send the ECU in, are tangible for me. I'm too busy for that to be as convenient as doing the up- and downloading myself.
Thanks much to Scott at
Softronic for a quality product, and to April for good customer service during the process!
