BDT Stage 1 ECU Tune — 2013–2014 VW Jetta GLI

ECU Verification Required: Simos 12.2 • FWD • DSG & Manual Supported

BDT Stage 1 sharpens throttle response, builds a stronger midrange, and delivers a smooth OEM+ powerband you can daily without drama. This is the tune that makes your GLI feel lighter, quicker, and more alive every time you roll into boost.

Built in-house by Boost Dynamic Tuning (BDT) — no reseller files, no mystery maps — just clean, repeatable performance with safety-aware logic.

Simos 12.2 ECU Verification (How To Find The ECU ID Label)

This is the fastest way to confirm you have the correct ECU. You’re looking for the ECU identification label/sticker directly on the ECU housing.

Where the ECU is located (typical)

  • Engine bay, near the battery and fuse panel

Location can vary slightly by production date and market. If you don’t see it immediately, check under the cowl/ECU box area.

What to look for on the label

  • A printed label/sticker on the ECU housing
  • Text indicating the ECU type (look for Simos 12.2

Best practice: take a clear photo of the full label and keep it for your records.

Quick Steps (safe & simple):

  1. Park the car, engine off, keys away from the vehicle.
  2. Open the hood and locate the plastic cowl area near the base of the windshield.
  3. Remove the rubber weatherstrip if needed and lift/remove the cowl cover (basic trim clips).
  4. Locate the ECU box cover and open it to expose the ECU.
  5. Find the ECU identification label on the ECU housing and confirm it says Simos 12.2.
  6. Take a clear photo of the entire label (no blur, no glare).

If you’re not comfortable accessing it, any shop can confirm the ECU label in minutes. Verification prevents wrong-file orders.
