BMW M5 E39 Touring ESS Widebody - First Startup & Dyno ECU Tune

Took the opportunity to drop in and film some footage @ Driftdarbnica in Riga, LV, where @sergey_ananic with help of Maris Rungis @ DriftDarbnica BMW shop was assembling Sergey's M5 E39 Touring Widebody ESS Supercharged's S62.

They assembled the newly sleeved & balanced (crank/rods/(custom) pistons) S62 and ESS'ed it in two weeks time, where two weeks ago the motor was disassembled to lowest common denominator, and today Sergey drove out of the country to head to an autoshow.

I showed up (late as always), but at least managed to film (and catch some of the emotions) of the final assembly, first start and dyno tune.

Note that the dyno was to check AFR's, etc., and tune, not for power output testing. That will come later once the engine has been broken after the road trip.
