Just wanted to share a recent ESS E-Flash before/after dyno session on a 2009 M3 with some minor bolt-ons. The only thing missing was a performance flash tune.
ESS's E-Flash was immediately added and the M3 strapped to the dyno. The results were
very impressive.
Vehicle
2009 BMW M3 DCT
Modifications
Macht Schnell Performance Filter
Fabspeed Resonated X-Pipe (primary catalysts intact)
Rogue UnderDrive Pulley
Remus Race axleback
Options
[X] Update to 240E (previously on 200E OS)
[X] Remove cold start cat heat cycle/camshaft phasing (for smoother cold starts)
[X] Retain OEM Rev limiter (customer specified)
[X] Remove top speed governor/VMAX
M3 was originally on 200E OS, which was updated to 240E before applying the ESS flash tune. Plugs were already changed approximately 500mi ago as part of scheduled maintenance.
As you can see, gains are achieved throughout the
entire powerband. Those with 93 at the pump can expect even better results
