Product Description
BMS N55 Stage 1 Tune
BMS Stage 1 BMW Performance Tuner
This plug and play tuner attaches to two easy to access sensors in the engine bay and works with your factory DME tuning to remap your boost, timing, and fueling for optimal performance and reduced turbo lag. It features a 64mhz processor allowing sensors to be sampled 800 times per second using dedicated 10 bit digital to analog converters, ensuring smooth and powerful performance. The same box automatically detects whether you have an N20, N55, or S55 motor based on the TMAP sensor voltage and adjusts the tuning accordingly.
Power gains on the N20 motor are up to 45 horsepower and 60 torque (35hp and 50tq at the wheels), on the N55 motor are up to 50 horsepower and 65 torque (40hp and 55tq to the wheels), and on the S55 motor up to 60 horsepower and 75 torque (50hp and 60tq to the wheels).
Installation is very discrete and it is quickly removed without a trace when needed. Fuel economy during normal driving is unchanged. Compatible with all driving modes.
Part F30-N55-STG1 is CARB Approved Under Executive Order (EO) No. D-744-1 for 2013 BMW 335i models only. All other applications are competition race use only and not legal for use within California.
