TuneBoss releases Suzuki VStrom 250 upgrade ECU

In a world’s first, home grown Malaysian motorcycle performance parts maker TuneBoss released a standalone ECU for the Suzuki VStrom 250 SX. The TuneBoss ECU fits the ASEAN model variant VStrom 250 SX, sold in Malaysia from 2023.

The ECU will give the VStrom 250 SX a boost of 1 hp and 0.3 Nm of torque, for the standard power curve. The impact of swapping in a TuneBoss will be most felt at between 4,000 to 8,500 rpm.

A completely plug-and-play performance upgrade, the TuneBoss ECU directly replaces the original equipment ECU from Suzuki. This is unlike other products from the competition where the performance ECU is a piggy back unit that intercepts the signal from the motorcycle’s ECU.

The TuneBoss ECU is fully programmable using an app on the rider’s smartphone and a Bluetooth connection. Two standard engine mappings are provided – for use with the stock airbag and with the airbox snorkel/intake hose removed.

Should other performance items such as air filters, exhausts and cams be installed, the TuneBoss ECU is ready to accept dyno tuning. This is because the ECU is programmed for professional tuning of fuel and ignition curves (Stage2).

Other features of the TuneBoss ECU are precise RPM limit setting, diagnostic feature, live data monitoring or data logging combined with GPS location, and an immobiliser function. For the advanced VStrom 250 SX engine modder, there is also the option of dual-injector control and electric-water pump control.

Pricing for the TuneBoss Suzuki VStrom 250 SX ECU is RM829 for the Malaysian market from authorised TuneBoss dealers. Global release of the TuneBoss ECU is expected to be second quarter 2026.
