Description: Our brains control our vitals. An EVO's ECU is no different. There is no single more valuable tool available to any tuner than the ability to access the car's brain and reprogram it to perform to its fullest potential -- especially after tuning parts have been integrated into the system. No piggy-back add-ons that intercept and falsify signals to the factory ECU and no standalone engine management systems compromising Mitsubishi safety functionality. The WORKS Brain Flash is the factory ECU that has been reprogrammed with WORKS Performance Software optimizing all applicable maps including the air/fuel ratios, ignition timing, and calculated rev limit. WORKS was the very first EVO tuner in the U.S. to reprogram the factory ECU. Our Software Engineers have been dissassembling U.S. EVO VIII code since April '03 and have software control unparalled in the industry. With the Brain Flash P1, expect a 20+ HP peak gain but more importantly a broad, usable, power curve with no other modifications that is very safe and reliable. In addition, expect smoother drivability and improved gas mileage. Nothing comes close to the plug-and-play performance and reliability of the WORKS Brain Flash. The WORKS Brain Flash RL is also available to customers who want to increase the factory rev limit to their desired RPM and increase the factory flow-cut limit. In either case the ECU can be reprogrammed back to stock if necessary and of course is backed by our Factory Matched 3-Year Warranty. Price: P1 $499.00*, RL $199.00** *please specify lowest octane fuel used and modifications if any **please specify RPM when ordering Availability: Now (same day turnaround) P2 Boost Enhancement to Brain Flash The Brain Flash P2 represents an upgrade to the Brain Flash P1 by peak and holding the factory peak boost level! The P2 provides addictive acceleration by eliminating the factory boost taper in the higher rpms. By eliminating this boost drop-off, the total area under the torque and horsepower curve is enhanced and the car responds with increased urgency as the power band winds up. WORKS' Engineers spent many months analyzing the stock boost control system. Then improved upon the factory design to bring you a true peak and hold system. There is no removal of factory inline flow restrictors or any attempt at fooling the ECU logic. This proprietary system represents a tried and true reliable design which takes the safe factory system one step further. With the unique WORKS Boost Hose Assembly (which appears identical to stock) and ECU boost mapping modifications, WORKS has total boost control. Of course the P2 upgrade involves a comprehensive performance ECU remapping of the air/fuel ratios and ignition timing to compliment the rock-solid peak boost.
