EQT's in-house tuning interface.

The Sauce Management Device — SMD — is EQT's new flash tool geared for the MQBe (VW MK8/Audi 8Y) platform. This is allowing us to add desired features like ECU based MPI integration to support higher power options like upgraded turbos and full E85. We are also working on adding new custom features like Flex Fuel, Custom Launch Control, Traction Control, and more.

Launch Support

The SMD is available exclusively for the MK8/8Y platforms. There is currently no timeline for support for any additional platforms.

Full Control in your pocket

Flash, Datalog, and Diagnose - All from Your Phone.

The SMD app gives you direct control over your tune from anywhere. Flash between maps, pull data logs for review, and read diagnostic codes all from your iPhone, Android, or Windows laptop

SMD Staged Tunes

Flash. Drive. Enjoy.

The SMD is the device staged tuning was meant to live on. Flash any map in your pack, switch between octanes on the fly, revert to stock anytime, and pull a datalog if you ever need to. One device, one app, every stage you bought — managed from your phone or laptop.

Staged Tune Map Packs

With the SMD, every staged tune now comes with a full Map Pack, every fuel and feature variation for your stage, bundled into one purchase. Switch between maps anytime from your phone or laptop, no re-tune required.

Pre-Built Calibrations

Performance you can feel, drivability you can live with, and a clear upgrade path from Stage 1 to whatever comes next.

SMD Custom Tuning

Built for the Way We Tune

The EQT SMD is built around simplifying custom tuning. flash a base map, send a data log, get a revision, flash again. The whole loop happens on your phone or laptop, on your schedule, with your calibrator one-on-one until the tune is dialed.

Support for Custom Hardware

The SMD supports the full range of EQT custom calibrations — upgraded turbos, multi-port injection, boost sensors, aggressive fueling setups, and the rest of what comes with a serious build.

Multiple Tune Revisions

Work with your calibrator one-on-one until your tune is perfected for your setup!

Live Tuning Sessions

Don't want to wait in-between revisions? We offer complimentary live tuning sessions so you can knock your tune out in just a couple of hours.
