INFINITI G35 (2014–2015) – 3.5L VQ35HR / 3.7L VQ37VHR V6
STAGE 1 / STAGE 2 PERFORMANCE SOFTWARE TUNE

*** STAGE 1 TUNE PERFORMANCE PACKAGE – ECU SOFTWARE ONLY (FLASHING OPTIONS BELOW) ***

AVAILABLE FOR BOTH MANUAL & AUTOMATIC TRANSMISSION / SEDAN & COUPE

Description

Stage 1 consists of an individual reprogramming of the engine management system, where ignition timing, fueling, throttle response, torque limiters and rev limit are recalibrated for safe, daily-use performance on pump fuel.

Stage 2 is a custom-adjusted calibration in which all relevant engine parameters are further optimized to accommodate additional modifications such as aftermarket sports exhaust, high-flow or catless headers, and upgraded cold air intake systems. Pops & Bangs calibrations are available on suitable hardware.

All maps are developed to deliver the best possible performance and results within safe operating margins, while retaining excellent drivability and street usability.

3. Remote OBD Tuning with BBS OBD2 Tool

• Vehicle is tuned via the OBD2 port using the BBS OBD2 cable and Windows flashing software.
• No ECU opening required; your original (stock) file is read and stored, then the tuned file is written back.
• You can return the car to stock using the same tool while your subscription is active.
• The BBS tool can be used to tune multiple vehicles; however,
  • Each additional vehicle requires the purchase of a separate base tune / Stage 1 file.
