JHM TCU (DSG) and Stage 2 ECU Tuning Bundle for B8-RS5 4.2L FSI

Introducing JHM Tuning for the B8-RS5 with the 32v 4.2l FSI V8!!!

Please note that your vehicle must be present at one of our shops in order to install this software if you do not have a JHM Power Connect Cable. Please contact us if you are interested in setting up an appointment.

NOTE: You MUST have JHM ECU software to run their TCU software due to the increased shift points and other features that require JHM ECU software to function correctly. If you do not currently have the JHM ECU software installed, you may add it via the option above.

JHM have specialized in tuning naturally aspirated (NA) or "all motor" 4.2L V8 engines since we started tuning the B6-S4 in 2008. Ever since then we have been the number one company when it comes to Audi V8 performance. Like our success with the B6-B7 S4, B7 RS4, and B8-S5 4.2L has shown, our software has been proven time and time again to deliver real world performance. That continues with our tuning for the B8-RS5 4.2L FSI V8. We purchased our in-house B8-RS5 4.2L in mid-2017 and immediately began developing software. After countless revisions and putting the vehicle through our rigorous R&D process, we are happy to now offer the ultimate performance software for your B8-RS5 4.2L FSI V8!

Why is JHM tuning the BEST? Their Stage 2 performance ECU and TCU software is specifically designed to work in harmony together maximize the engine power output capabilities.  Following their success with the B7-RS4 and B8-S5 4.2L FSI Performance Software, JHM began extensive research and testing with their in house B8-RS5 4.2L. JHM's tuning will give your RS5 improved throttle response and more power throughout the entire RPM range leading to faster acceleration and a much more rewarding and refined driving dynamic.

By making a ECU and TCU combination that works together JHM is able to do the following for your RS5:

• Engine Rev limit increased to 8800rpm
• More aggressive throttle control in Sport Mode
• Increased shifting speeds
• More assertive shifting in Sport mode and after using Launch Control
• 1-2 short shift issue in factory file fixed and raised from 7800 rpm to ~8500 rpm
• All other gears raised from 8300/8400 rpm to 8500 rpm
• Launch Control RPM raised from 5500 to 6300
• Launch Control attempts raised from the 200 max limit to unlimited
• More aggressive and consistent Launch Control
• Refined Drive and normal driving shifting
• Current gear displayed on dash in all modes
• "True Manual Mode" Manual Mode holds and will not down shift or up shift (OPTIONAL)
• Higher pump speeds for transmission cooling.
• Higher clutch pressures at all RPM and LOADS
• Raised TQ limiters

Performance:

JHM's preliminary testing has shown exceptional results of 11.88@115mph on 91 Octane and in this video 11.89@116mph

Additional Benefits:

In addition to optimal performance, our JHM Stage 1 Performance Software significantly improves the RS5s EGT (Exhaust Gas Temperature). This is beneficial because lower EGTs will improve catalyst life, and better engine protection for long periods of hard use for Road Racing, Autocross, Etc..

Recommended Supporting Modifications:

• High flow downpipes and cat-back exhaust

Fitment/Applications:

• 2010-2017 Audi B8, B8.5 RS5
