Transmission Upgrade: 2007-2009 Porsche Turbo TCU Upgrade
The 997TT Tiptronic Control Unit (TCU) is responsible for controlling the transmission functions such as shift speed, shift RPM, torque and many other transmission related activities. Our TCU upgrade improves these functions to improve the overall performance of the tiptronic transmission. We carefully disassembled and monitored the TCU functions while driving on our AWD dyno with an EPROM emulator. This allowed us to tune in real time and monitor the changes and how they affected the performance. The final result was a drastic improvement to the overall drivability, shift speeds and raised rev limit to make use of all of the engines power up to 7000 RPMS. Performance…Engineered and EVOLVED The EVOMSit TCU upgrade incorporates the following functions:
> Increased Rev Limit – 7000 RPMS*
> Increased TQ Limits
> Quicker Up and Down Shifting
> Price: $1000
*The ECU rev limiters must also be calibrated to allow higher TCU shift points. We offer various different ECU/TCU programming options to suit your specific requirements. TCU must be sent to EVOMS for upgrade. Same Day Turnaround. Extensive real world testing has been conducted throughout the world on many high powered 997TT tiptronic cars. Our development partner EXELIXIS ( http://www.dynoexelixis.gr) in Greece has conducted over 10,000 test kilometers of driving on 2 different cars with this TCU upgrade. The development cars were both fitted with 700 + HP engine upgrades. One car has made countless 1/4 mile launches recording a best time of 10.6 seconds @ 214 KPH (132.68 MPH) See the following thread to
see this car in action – posted by the car owner and 6-speed member – Kakimoto – The additional test car is a top speed car that gets constantly pushed at high loads and RPM levels for prolonged periods of time.
