Up to 450 hp and 635 Nm (468 lb-ft) at the crank!
Cars with stock exhaust system

Designed for the drivers who want the most out of their stock component vehicle. This software is intended to safely maximize your vehicle’s potential performance. The power curve has been delicately engineered to eliminate any dips in the overall powerband as well as maximizing delivery of that power throughout the entire RPM range.

MG Flasher Custom Code allows users to goes beyond factory 550 Nm limit!
See Transmission Limiter information below.

TECHNICAL INFORMATION

- NBT Display HP/TQ gauges calibration
- Torque limiters
- Lambda optimization
- Ignition timing optimization

Additional options available with each OTS map
- Adjustable exhaust burble and engine cooling
- Speed limiter removal
- Cold start delete (off-road use only)
- Catalytic converter delete (dcat, off-road use only)
- Exhaust flap control

TRANSMISSION LIMITER INFORMATION

Software calibration without the need for any transmission tuning or skewing the torque/load calculation model maps. This allows for accurate calculations, smooth shifting and no software trickery. The factory torque limiter is set to 550 Nm (400 lb-ft) at the crank. We are the first to offer a solution to lift this limit up to 1000 Nm by using our custom code! The limit is adjustable in app.

TRANSMISSION LIMITER INFORMATION

The 340i is equipped with an 8HP50 transmission where the factory torque limiter is set to 550 Nm (400 lb-ft) at the crank. For the best results and proper smoothing of the torque curve without any transmission related torque intervention we have found that is best to increase the limiter within the transmission software. We present you with two options to implement this on your vehicle:

Option 1: Lifting the limiter in the transmission ECU which can be done for example with xHP Flash tool
Option 2: Bringing the car to our shop or another tuner for reprogramming of the transmission ECU limiters
