One of the most common, cost effective performance modifications is accomplished via ECU Tuning.
Modern vehicles are equipped with an Engine Control Unit (ECU) that controls various engine parameters. Manufacturers commonly "leave some on the table" via conservative calibrations in the quest for fuel economy, driveability and reliability/longevity.
Aftermarket tuners are able to unlock more power/torque and enhanced throttle response via optimized ECU Tunes (also commonly referred to as 'maps' or 'calibrations'). Methods of extracting more power via ECU Tuning varies per car but ultimately is accomplished by optimizing fuel, throttle and spark maps, camshaft timing and boost pressure (in forced induction applications).
When upgrading hardware components (exhaust, intake, turbo upgrades etc), tuning can not only help you to net more power but can often be required for proper, seamless driveability.
Now that we understand the basics of ECU Tuning, let's discuss a few different methods, which can vary by manufacturer/model:
Bench Flash
A bench flash is when the ECU (or ECUs) is physically removed from the vehicle and flashed on a bench. Upon completion, the ECU is re-installed into the vehicle with the new calibration.
OBDII Port Flash
With advancements in tuning technology, it has become quite easy to flash the ECU via the OBDII port, which is typically located under the driver's dash. A tuning device is plugged into the OBDII port and the new tune file is written to the ECU.
OBDII flashes eliminate any down time as the ECU does not have to be removed and sent to a tuner. They also provide the option to easily retune the car or flash back to stock if necessary.
Piggybacks
While technically not an ECU Tune, Piggyback tuning devices are popular due to the fact that they do not impact the ECU Flash Counter, which is something to keep in mind when it comes to warranty concerns. The Piggyback device can often be removed without a trace.
Piggyback devices plug into various sensor inputs to 'trick' the ECU into compensating for more boost pressure, more fuel etc.
Choosing the right tuner is NOT a simple roll of the dice. Many will chase a 'glory run' on the dyno, often at the expense of reliability and longevity, for an inflated power gain. We are of the belief that safety always comes first, while still chasing improvements across the board.
From mild to wild, we have solid tuning options available from the industry's top calibrators.
