We’ve updated our APR Plus and APR Stage 1 ECU Upgrades for the B9 RS4 and RS5 2.9 TFSI EA839 V6. The update feature a new launch control routine that allows for a better launch off the line while also adding protection for the driveline. Additionally we’ve adjusted an RPM fluctuation that occurred on some vehicles during a cold start. This update is now available across the globe for free and is listed as Version 1.3.
