Online Shop

Upgrades your existing BMS Stage1 to a EA888 JB4 BETA system. The JB4 BETA features CANbus connectivity for more advanced tuning, direct AFR control, advanced safety systems for boost, air/fuel ratio, fuel trims, and engine knock, boost mapping by gear for improved traction, integrated water/meth control, and much more.

The introductory upgrade cost is £60 plus a £85 core charge. Original purchasers of the Stage1 hardware can return their Stage1 board back after the swap along with a purchase receipt to receive a £85 core refund. If you did not purchase your Stage1 hardware new from BMS or an authorized reseller you can still return your Stage1 board back to receive a £35 core refund. Core refunds must be submitted within 30 days of upgrade kit shipment to qualify. This JB4 requires exclusive OBDII/CANbus access while tuning is enabled and is not compatible with various CANbus enabled boost gauges or 3rd party devices that also require OBDII/CANbus.

When ordering use the drop down to specify left or right drive hand and your Stage1 hardware version. Vehicles in the USA and most other countries are left hand drive (LHD) while UK, AU, SA, and a few others are right hand drive (RHD). For the Stage1 hardware version systems purchased after approx 11/1/16 are REV2 and can be identified by an unused black Molex/2 position connector already incorporated in to the harness. Check the installation guide below for additional information on identifying your existing hardware.

BMW M235i Scorpion Exhaust

BMW M235i

Scorpion release a large bore high flowing turbo down pipe and cat-back exhaust system for the BMW M235i.

Reconsigning the potential of the inline 6 cylinder turbocharged engine the Scorpion R&D engineers developed a high flowing T304 Stainless Steel cat-back exhaust system which features 90mm Daytona tail pipes and our active exhaust valve which works with the drive ‘mode’ button inside the car.

Further enhancing the M235i, Scorpion have developed a big bore 100mm turbo down pipe which is fully interchangeable with both our cat-back, and the original exhaust meaning you can upgrade at any time. This option is available with a 200 cell high flowing sports catalyst or de-cat depending on customers preference.
