New best fuel economy and 0-60 (M40i stage 2)
On Monday I drove 320 miles (~500km) through the mountains back home. Drove like a granny, speed limit or a little over.
BM3 stage 2, catted DP, and I recently added xHP stage 2 trans tune. Trans tune feels good, not sure it's helping my acceleration. Got 7.1L/100km or 33.1MPG. Super happy. Got home and tried a 0-60 now that I have launch control figured out. 3.99. The 60ft time worked out to be 1.80 sec. I think I can get it down a little more. My prev best 60ft time (no launch control, no trans tune) was 1.85 so there's gotta be more on the table. Prev best 1/4mi time (no launch control, stock trans tune) was 12.44 at 110mph. I didn't run the 1/4 out this time, but I'm guessing 12.35 having shaved 0.05 off the 60ft time. Love the car. |

Nice!
What do your XHP settings look like?

It's just default stage 2. Except:
- Launch torque (+5%) - Torque scaling after launch (+5%) - Line pressure bump. There's no real tire slip on launch. I could apply more aggressive launch settings, but I'm trying to be safe with the trans. |
