I am fairly confident with driving the X5M to let the ECU learn the new parameters, the car would have continued to pick up additional power. I plan on heading back to the dyno next week for final numbers. Whether the settings impacted the numbers, or the ECU learning the new parameters, I will know after I redyno.
I did multiple pulls with the Eurocharged tune trying different settings. All runs were done with traction off after the M Settings were initiated. This was done by holding the traction button on dash for 5 seconds until beep is heard.
The next three setting pulls are shown in Dyno2
First pull with tune :
M Mode Settings:
466 / 482
This resulted in a very jumpy tq and hp curve. Again, not sure if this was because it was just loaded, or if the DSC off and traction off caused this.
Second pull with Eurocharged tune installed:
Non M Settings
Shifter pulled to Sport
Traction off : holding traction button on dash
Resulted in much smoother tq and hp curve
462hp / 503tq
Third pull with Eurocharged tune
M mode settings
Shifter pulled to Sport and manually holding 4th gear
Each pull the truck made more power and I have a feeling if u would have driven it 20 miles for the ECU to learn the new settings, it would have gained more.
My wife actually complained about the truck not having the same low end grunt our previous X5 50i with Dinan Stage II had. I agreed completely with her, but after this time I am confident she will agree with an extra 80 lb-ft tq at 2500. In comparison, the 2012 put down 380/450 on the same dyno.
I am very happy with the tune. Once the weather breaks and the track opens, I will let you know the 1/4, 1/8 and trap speeds.
On a side now, while I was at the shop, my AMS Alpha 9 Motor, Turbos and Transmission motor showed up for my GTR so it was refreshing to see. Hope to make 900+hp / 800+tq on the same dyno.
Definitely cannot go wrong with this tune or Eurocharged. I am planning on having them tune my 550ix which is currently on a Dinan Stage II.
