COBB Tuning Accessport V3 for Porsche 991.1 Carrera (All Naturally Aspirated)

Select the COBB+IPD+TB package above, save on max performance!

The COBB Accessport V3 is the world's best-selling, most flexible ECU upgrade for all naturally-aspirated Porsche 991.1 Carrera models. Unlock power and torque masked by Porsche's conservative, one-size-fits-all factory ECU tuning by downloading COBB's more aggressive calibrations and mapping.

Plus, easily upgrade forever as you add future modifications to your engine with COBB's off-the-shelf (OTS) calibrations professionally designed for most of the popular bolt-on Porsche modifications. It's truly the last engine management solution you'll ever need.

Once you receive your Accessport, you just download the tuned map(s) of your choice from COBB's customer website, then upload them to your car's ECU via the OBD2 port. It's simple and easy, requiring only about 20 minutes! You can also save your original factory tune so you can change the ECU back to 100% stock anytime. 

Stage1 maps are designed for a stock engine configuration, though their design flexibility allows them to work well with the IPD Competition Plenum and throttle body upgrade.

The Accessport V3 has a large, full color, higher resolution TFT screen that allows you to monitor up to six parameters in real time. Fully customizable look (multiple bezel colors and styles are available), layout (set up a race, street or dyno gauge cluster) and dozens of mounting options. Of course, a full range of unparalleled COBB tuning is included, with enough space for 100 calibrations. This is your new Accessport - the last tuning device you'll ever need.

Warning! Installation of this Accessport over anything other than OEM or COBB software may result in ECU/TCU failure. Please contact us at (844) 438-7244 if you have any questions.
