WHAT IS ECU TUNING?

ECU Tuning should be the first and last modification for any modern combustion engine. ECU tuning is the modification of the code within a car’s brain which controls how much power the car makes, how much fuel it uses, what the top speed limit is, etc.

As ECU Tuners, our job is to read out the stock code, modify it to make safe power, and program it back into the computer using factory-level OEM tuning tools with correct checksums so no one, including the dealerships, will be able to tell there has been any modification.

The result can be over +100 horsepower*, much more than any exhaust or intake system can yield and by using the factory computer, retains OEM safety parameters to keep your engine running strong and healthy for years to come.

OUR STRATEGY

We do not just change ignition timing and air-fuel ratios, we go much deeper in the file to find hidden power in the form of “torque limits.”

Torque limits are how modern ECU limits power and efficiency. A torque limit can be any limit on the throttle, boost, timing, or fuel.

The painstaking process of reverse engineering that HD Tuning undergoes for every new model includes purchasing Damos files from the manufacturer in order to define and scale the 8 megabytes+ of binary data in the current generation ECU’s.

ABOUT HD TUNING

HD Tuning was started by Matt Bekam to provide premium engine calibrations for most European and luxury vehicles. Matt has been tuning vehicles for a decade and before branching out on his own was doing tuning for the likes of Powerchip, Evosport, Weistec Engineering, BBI Autosport, Brabus, and many more.

The HD moniker was appropriated because of the great detail Matt goes into to extract maximum power out of a vehicle while retaining reliability.

Oftentimes these map definitions are in automotive German and abbreviated, which is a difficult task in and of itself, but with these tools, we are able to extract more power than the competition and do so safely on all fuel types regardless of mods.
