CADILLAC ATS 2.0 L LTG (2013-2019)

STAGE 1 & STAGE 2 PERFORMANCE SOFTWARE

OVERVIEW

Our performance software for the Cadillac ATS 2.0 L LTG turbo engine brings significant improvements in horsepower, torque, throttle response, and everyday drivability. All calibrations are developed in-house and specifically tailored for the LTG platform using advanced boost, ignition, load, and torque mapping.
Stage 1 is designed for stock or lightly modified vehicles. Stage 2 is for vehicles with upgraded intake and exhaust to fully support increased airflow and load.

WHAT STAGE 2 INCLUDES

Stage 2 involves a full recalibration of the engine management system. Major parameters — boost level, ignition timing, fuel delivery, throttle mapping, torque limiters, airflow/load modelling — are optimized for:

• Aftermarket cat-back exhaust
• High-flow or catless downpipe
• Upgraded cold air intake

These enhancements deliver stronger mid-range torque, improved turbo spool, and maximum safe power.

FEATURES

• Speed limiter (governor) removal
• Sharper throttle response
• Rear O₂ sensor delete (DECAT) included in Stage 2
• Optimized for 91–93 octane
• Improved fuel efficiency
• Fully custom ECU reprogramming
• Enhanced responsiveness & drivability
• Optional datalog review & analysis

SOFTWARE OPTIONS

Stage 1 (89/91 Octane) — Requires: K&N drop-in filter
Stage 1 + Pops & Bangs (89/91 Octane) — Requires: K&N filter & cat-back exhaust
Stage 2 (91/93 Octane) — Requires: Cold air intake & cat-back exhaust
Stage 2 + Pops & Bangs (91/93 Octane) — Requires: Cold air intake & cat-back exhaust

BEFORE / AFTER DYNO-STYLE POWER GAINS

Estimated improvements:
• ~+58 hp over stock (Stage 2)
• Substantial mid-range torque gain
• Improved throttle response and turbo behaviour

PROGRAMMING OPTIONS

The Cadillac ATS 2.0 L LTG is fully compatible with the BBS OBD2 Flashing Tool — enabling OBD-read/write capability through the OBD port.

BBS FLASHING INSTRUCTIONS (OBD2)

1. Install BBS Windows software, connect Senselock dongle if required.
2. Connect the BBS OBD cable to the vehicle’s OBD2 port and USB to laptop; turn ignition ON (engine OFF).
3. Launch BBS software, select LTG/E80 protocol, perform initial read. Upload the file to AMT Tuning.
4. Wait for tuned file (typically 24–48 hours).
5. Load tuned file in BBS software, write via OBD. Do not unplug or cycle ignition during write.
6. The BBS tool stores one tune at a time — request additional files (stage upgrades, pops & bangs) as needed.
7. Your original stock file remains backed up and can be restored anytime.
