B9/B9.5 Audi SQ5 Accessport Tuning

Expanding our Accessport support of VAG vehicles, we’re proud to announce release of Audi tuning support for the B9/B9.5 Audi SQ5!  These little SUVs respond surprisingly well to tuning with the 3.0L turbocharged V6 engine providing substantial torque and power gains over stock allowing them to have the GO to match the SHOW and hit above their weight class.

The SQ5 Accessport

Simple ECU flashing with gauge package! The in-cabin mountable Accessport V3 has a large, full color, high resolution screen which allows you to monitor up to six parameters in real time. Fully customizable from the look (multiple bezel colors), layout (set up race, street, or dyno gauge clusters), and mounting options (choose from 1,000s of standard vehicle mounts). And what’s looks without brains? More processing power, memory, and storage to flash faster while saving all of your maps and logs. This is your new Accessport.

This part is legal for sale and use on Emissions Controlled Vehicles in all 50 states when used in accordance with the manufacturer’s application guide because it has a California Air Resources Board (CARB) Executive Order (EO) number: D-660-157

Vehicles Supported

Audi SQ5 Stage 1 OTS Map & Power Gains

Included with the Accessport are COBB Stage 1 Off The Shelf (OTS) Maps, intended to be used on an otherwise stock SQ5.  An upgraded cat-back exhaust or panel filter in the factory airbox are able to be used with these calibrations.  Each map file requires a specific fuel rating, either 91 or 93 octane (or better).  As you can see in the dynamic dyno chart below, low end torque is significantly increased using either map.  Peak Torque is increased by 19% on the 91 file and just over 23% using 93 octane.  Power delivery is also much smoother when compared to factory.  While a majority of the gains are observed in the low and mid range, peak power is increased a bit as well.


Accesstuner Pro Custom Tuning

For those interested in custom tuning, our Accesstuner Pro software also now supports these vehicles.  Any of our Authorized VW/Audi Protuners can create a custom calibration for use with your Accessport.  Find a COBB Porsche Protuner HERE.

  1. I’m new to Cobb. What would I need to purchase for my 2021SQ5.? I can also assume this is “dealer safe “?

    Does this just plug into the ODB connector or do I have to plug it into my ECU and such like the db4 units?

    • Hey Damon! All you need is the Accessport. Our AP3-VLK-004 Accessport supports the B9/9.5 S4, S5, and SQ5 and will come pre-loaded with Off The Shelf Maps for each respective car. To install, you simply connect to the OBDII port under the dash and choose which map you’d like to flash. The on-screen instructions are very intuitive. Regarding “dealer safe” – we do recommend Uninstalling the Accessport prior to taking your car in for service in case the dealer needs to update the ECU.


    • We haven’t seen a MY24 SQ5 to confirm on just yet. If you have an AP handy and can plug in to identify the ECU we can let you know if it has a ROM version that we already support.


    • We have yet to have a MY24 SQ5 in house to confirm compatibility. Any chance you know the ECU ID from your SQ5 or are in the Austin, TX area?
