How Remote Tuning Works

Flash your RS7 from home — no shop visit needed.

 
1

Schedule Your Flash — After purchase, scan the QR code or contact BDT to book your appointment.

2

Download TeamViewer — Install on your Windows laptop. BDT remotes in to run the flash software.

3

Hook Up Battery Charger — Positive first, then negative. Stable voltage is critical on V8 platforms.

4

Turn Car to Accessory Mode — Press start without brake. Do not start the engine.

5

Plug In OBDII Cable — Connect to the OBDII port (driver side, under dash).

6

BDT Takes Remote Control — We handle everything. You watch the entire process live.

7

Key Off on Command — When BDT says “turn key off,” do it immediately.

8

Disconnect & Drive — Unplug OBDII, remove charger (negative first, then positive), start the car, enjoy.

Post-Flash Note: You may see a few fault codes after flashing — this is normal. They clear after a short drive cycle.

HOW REMOTE TUNING WORKS

Frequently Asked Questions

 

Q: Will Stage 1 work on my stock RS7?
A: Yes. Stage 1 is designed around fully stock hardware — stock turbos, stock intake, stock exhaust. Just make sure maintenance is up to date and you’re running 93 octane.

 

Q: Is a high-flow exhaust compatible with Stage 1?
A: No. If you have a high-flow exhaust, you need Stage 2. Stage 1 is specifically calibrated for stock exhaust.

 

Q: What’s required for Stage 2?
A: A high-flow exhaust is required. TCU tune, intake, intercooler, drivetrain inserts, and NGK R7437-8 spark plugs are highly recommended to get consistent power.

 

Q: Do I need a TCU tune?
A: Highly recommended on both stages. The ZF 8HP transmission is already one of the best in the world, but the factory TCU caps torque handling and shift aggression. A TCU tune unlocks harder shifts, higher rev limiters, and full torque passing.

 

Q: Can I daily drive this tune?
A: Absolutely. BDT Stage 1 and Stage 2 are calibrated with safety logic intact — knock control, IAT protection, and OEM-style fueling strategy. Drive to work all week, hit the drag strip on Saturday.

 

Q: What fuel does this tune support?
A: 93 octane required. Lower octane will pull timing and hurt power. Do not run 87 or 89 — knock events on a tuned 4.0T V8 are expensive.

 

Q: How does it compare to the S6, S7, S8?
A: Same EA824/EA825 4.0T V8 block family — but the RS7 runs different turbos, different boost targets, and a different ECU strategy than the S6/S7/S8. BDT’s RS7 file is calibrated specifically for the RS7 — not a ported S6 file.

 

Q: Can I flash at home?
A: Yes. Remote OBDII flashing with full guided support is included. Windows laptop required, 50+ Mbps internet, 8GB+ RAM.

Maintenance (Read This)

IF YOU WANT YOUR CAR TO SURVIVE, THESE MUST BE DONE!

The 4.0T V8 is a bulletproof engine when maintained — and an expensive problem when it’s not. These intervals come from years of tuning RS7, S6, S7, S8, and Q7/Q8 platforms. If these aren’t kept up, failures happen — and it won’t be the tune. If you can’t afford the parts, please don’t tune your car.

    Exceptional Tune

    Posted by Zora Minhas on Sep 29th 2024

    Trent was great and took the time to accommodate all of my requests and make sure my vehicle had the best tune possible. It absolutely flies now and shoots insane flames. Fell in love with it again! Highly recommend
