EVOMSitECU Tuning for 957 Cayenne S / GTS

Evolution MotorSports has released two new performance system for the latest generation Porsche Cayenne Turbo and GTS models, incorporating our exclusive EVOMSit performance ECU calibrations. EVOMSit-intelligent tuning performance software upgrade for the Cayenne Turbo and Cayenne GTS represent the apex of technology which fuses optimum performance with unmatched reliability. Every aspect of the EVOMSit software development is conducted and tested on our state of the art in-house AWD dyno cell at our engineering facility and proving grounds located in Tempe, Arizona.

The EVOMSit performance software for the Cayenne S & GTS DFI 4.8L engine yields 19 HP / 22 TQ when optimized for 91 Octane fuel and 21 HP / 25 TQ when optimized for 93 Octane fuel. When coupled with an EVOMS V-Flow air induction system those number increase to 27 HP / 29 TQ (91 octane) and 29 HP / 31 TQ (93 octane).

The Evolution MotorSports performance systems for the Cayenne Turbo and GTS utilizes the Intelligent Tuning of EVOMSit. These new direct injection engines incorporate a Siemens SDI4 ECU which is a first for Porsche. This ECU is far more sophisticated than the earlier generation Cayenne Bosch ECU. The tuning capabilities were put to the test during these two projects and we have demonstrated that our intelligent tuning stands ahead of the rest. Not only are the power gains and overall performance phenomenal, but are the first of their kind from a US company.

The EVOMSit TUNEit handheld unit is included with your ECU Tuning purchase. This unit allows you to download and install our performance software via your car's OBDII diagnostic port. Simply plug in the handheld unit via included OBDII cable, read out your file, and email it to us. (Access to an email-enabled computer with USB port is done via the included USB cable.) We will email you back (usually within 24 hours) a performance file that you can upload yourself.

NOTE: Installation requires the use of an automobile BATTERY CHARGER (10+ AMP)

EVOMSit Run 1: EVOMSit TZv2 Software, EVOMS Dual V-Flow Air Intake System
EVOMSit Run 2: EVOMSit TZv2 Software Calibration
Baseline Run 3: (Black Run) Baseline - ALL Stock

Power is measured at the wheels on our Mustang 500 SE AWD dyno in a controlled environment for accuracy. Dyno runs shown are the average runs of a 10 run sample group for both the Baseline and EVOMSit modified runs. Dyno runs are accurately run with the same RPM start point, same transmission gear, same performance mode (sport or non-sport) and same cool down time in-between runs. Measurement was made with 1 x 65,000 CFM main cooling fan in the front of the vehicle with 2 x 5000 CFM "spot" cooling fans directed at the front radiators. Dyno room temperature was 92.7 degrees Fahrenheit for both sets of run groups and fuel grade was 100% pump 91 octane AZ grade oxygenated fuel.
