Heads-up on cancellations & returns: if you cancel an order or return an item, you won't get back 100% of what you paid. We apply a 10% restocking fee, the outbound shipping is non-refundable, and we have to pass on Shopify / PayPal payment processing fees; these aren't returned to us when we refund you. International orders also lose on exchange-rate spread in both directions. If the original packaging is damaged or missing, a reboxing charge applies. For international orders specifically, if you refuse to pay our shipping invoice or supply a prepaid label after placing the order, the same deductions apply. We're upfront about this — please be sure of your purchase before ordering.

Unlock serious performance from your Fiat Abarth with the JB4 plug and play tuner. This intelligent piggyback ECU works alongside the factory calibration to optimise boost, timing and fueling, delivering quicker spool, reduced turbo lag and power gains of up to 40 whp and 40 wtq on a standard car. No ECU flash is required, and it remains compatible with locked ECUs, making it a superb remap alternative that is fully removable.

  • Plug in installation to two engine bay sensors with advanced CANbus OBDII integration for real-time tuning and safety
  • Up to 40 whp and 40 wtq on a stock vehicle with smooth, factory-like drivability
  • Preloaded with up to 8 maps covering stock, 91 octane, 93 octane, E30/E85 blends, unleaded race fuel and Valet mode, plus boost by gear
  • Read and delete fault codes, log and view extensive live data, and switch maps via the optional JB4 PRO Bluetooth adapter and smartphone app
  • No ECU unlocking or flashing, not VIN-locked and can be removed without trace; fuel economy unchanged during normal driving
  • Rugged billet aluminium enclosure, designed and assembled in the USA with a 5-year warranty

The JB4’s CANbus functionality takes key data directly from the ECU, including throttle and pedal position, timing advance, fuel trims, air/fuel ratio, knock feedback and gear, allowing precise adjustments for strong, consistent performance. Always refer to the JB4 mobile app map descriptions for the latest guidance when changing maps.
