ESS Tuning changing the game with the release of their E-Flash for the F80/F82 M3 & M4

ESS is changing up the tuning game with their revolutionary E-Flash for the F80 M3 and F82 M4!

ESS’s new S55 Stage 1 E-Flash Performance ECU software is a full OBD2 solution that does not require sending in the ECU or opening the ECU in any way.

The Stage 1 E-Flash has been carefully developed to work with normal pump 91-93 octane fuel to develope a tune that maintains an OEM level of functionality an safety combined with excellent engine response and feel. ESS has chosen to stay conservative without forcing any ignition timing in the high RPM range and with a linear and very efficient powerband, the vehicle is still easy hook up and utilize in everyday traffic.

The result of all of their engineering? A plug and play OBD Flash that yields power increases of 50WHP and 70-80 ft/lbs over stock. This means 550+ HP and 560+ ft/lbs!

The E-flash has additional features such as minimizing turbo lag using the vanos of the turbo and air/fuel control, removed top speed limiter, increased RPM limit, extended power scale for the in cabin instruments, removed cat check option, removed cold-start cat heat up cycle, GTS Spec startup and overrun exhaust valve control, and calibration available for upgraded turbos and/or highflow or catless downpipes.

An interesting note that came out of ESS’s extensive tuning is that they have found the stock airbox has virtually zero restriction. This means that BMW has engineering the best possible airbox for these vehicles.
