Performance Engine Software was created to compliment our sister company, Performance Engineered Systems. Already known worldwide for our performance engine harware, we have now expanded to the high tech world performance ECU tuning. Our goal is to create the best ECU tuning available for the widest range of enthusiast sports cars and sedans. Below is a more detailed description of ECU tuning and what we do....

A vehicles ECU (electronic control unit) controls all of the engines operating functions. These include fueling, timing, turbo boost, throttle control, etc. There are also hundreds of algorithms which make multiple adjustments to engine functions dependant upon current operating conditions such as intake temperature, barometric pressure, fuel quality, etc. 

 Vehicle manufacturers typically tune the vehicles ECU very conservatively, leaving unused performance available. PES precisely adjusts the ECU “maps” that effect performance such as fuel, timing, boost  pressure, and throttle response, and raising or removal of speed governors. All of the engines safety parameters are left in tact. Part throttle fuel and timing are optimized to deliver better highway fuel economy and smoothness as well. The result is a car that has better driveability that standard with much more available power and performance. The overall reliability and longevity of the engine are not compromised.

You will notice that we concentrate a lot of our efforts on increasing the engines torque. Not only do we create chips with the more torque, but we make it available at lower RPM’s than standard. This gives you crisp off the line performance that you can really feel.
