⚠️ SOFTWARE REQUIREMENTS: Windows PC or laptop required for remote flashing. 50+ Mbps internet • 8GB+ RAM • TeamViewer installed. Mac is not supported at this time.
How Remote Tuning Works — Flash From Home in Minutes
No shop. No tow truck. No downtime. Your entire ECU calibration is completed from your driveway — BDT logs into your laptop remotely and handles every button press.
What You'll Need
- Windows laptop — macOS / Apple not supported
- 50+ Mbps internet connection (stable, no hotspot)
- 8GB RAM minimum
- BDT remote tuning cable (included with purchase)
- Battery charger — 10–25 amp, connected during the entire flash
- TeamViewer Quick Support — free, BDT walks you through it
Step-by-Step
1
Schedule: Scan the QR code included with your cable to book your session on BDT's scheduling page.
2
Download TeamViewer Quick Support: Google "TeamViewer" → click Quick Support → download and install. This gives BDT secure remote access to your laptop — no IT experience needed.
3
Connect battery charger: Hook up positive terminal first, negative last. Set to 10–25 amps and leave it connected the entire session.
4
Key on, engine off (accessory mode): Press the start button with no foot on the brake. All dash lights on — engine does not start.
5
Plug in the cable: Connect the BDT tuning cable to your OBDII port (lower dash, driver's side) and the USB end into your laptop.
6
Share your TeamViewer ID & password: BDT logs into your laptop remotely, selects your exact calibration file, and loads it to the car — you watch it happen in real time.
7
Key off on command: BDT tells you exactly when. The car resets all modules — temporary fault codes are completely normal and will clear on their own.
8
Disconnect & drive: Remove charger (negative first, then positive), start the car, and go.
The whole flash takes about 15–20 minutes. BDT is live on call with you the entire time. You never click a button you're unsure about.
WATCH: HOW REMOTE TUNING WORKS
After the flash: Your car may show fault codes across multiple modules — this is 100% normal. When one module is flashed it tells every other module to reset. They clear on their own after a short drive cycle.
Can't make your scheduled time? Reschedule at least 1 hour in advance. Late arrivals without notice are subject to a $50 fee.
Frequently Asked Questions
Q: What mods are required for Stage 1?
A: None. Stage 1 supports stock hardware. Intercooler and intake are recommended for best temps.
Q: What mods are required for Stage 2?
A: A high-flow exhaust is required. Intercooler, intake, and drivetrain inserts are strongly recommended.
Q: What do the E85 stages require?
A: Both E85 stages require a true flex fuel sensor, TCU tune, and HPFP upgrade. Stage 2 E85 also requires a high-flow exhaust.
Q: What mods are required for Stage 3?
A: Turbo upgrade, high-flow exhaust, TCU tune, intercooler, air intake, HPFP, LPFP, and MPI 980cc injectors. Full build required.
Q: How does true flex fuel work?
A: With a flex fuel sensor installed, the ECU reads ethanol content in real time and adjusts boost, timing, and fueling automatically. Run 93 octane, E30, E50, E85 — or anything in between. No reflash needed.
Q: Is Stage 1/2 safe on the stock IS20 turbo?
A: Yes — when maintenance is followed. Both stages are calibrated around safe boost targets with IAT/EGT protections.
Q: What fuel do I need?
A: Stage 1 and 2 (93): Maps 1–3 run on 91/93 octane. Map 4 requires 100 octane. E85 stages: any ethanol content from pump gas to full E85 via flex fuel sensor.
Q: Do I need a TCU tune for DSG?
A: Not required for Stage 1 or 2 (93 octane), but highly recommended. Required for E85 stages and Stage 3.
Q: How does multi-map switching work?
A: Switch between 5 maps on the fly using cruise control buttons. Each map has its own boost/behavior so your TT can go from daily to race to valet in seconds.
Q: Do I need a Windows computer?
A: Yes. The flashing software requires Windows. Mac is not supported. 50+ Mbps internet and 8GB+ RAM required.
