Mahindra Bolero-powered Roxor tuned to produce mad power [Video]

Mahindra Roxor is a big hit in the USA market. It is only available in the USA right now and is being sold as All Terrain Vehicle (ATV). It is not road legal in the United States but it has been picked up on the radar of many modders and custom vehicle makers. There are quite a few examples of modified Mahindra Roxor ATVs in the USA. Here is one such modified Roxor that has been tuned to produce much more power than the stock.

The Mahindra Roxor is powered by a 2.5-litre turbocharged direct injection engine that produces a maximum power of 62 Bhp and a peak torque of 180 Nm. The engine is mated to a five-speed manual transmission and a 4X4 system. It also gets a low-ratio transfer case that makes it much more capable on the off-roading trails. The 2.5-litre engine is the same engine that powers the Mahindra Bolero in the Indian market.

Dirt Legal, a USA-based modification house has re-tuned the Mahindra Roxor’s ECU to make it produce more power. The ECU has been flashed and new software has been installed on it so it produces more power. While the engine of the Roxor produces a maximum of 62 Bhp, the power reaching the rear wheels of Roxor is only 52 Bhp due to the various power leaks like transmission loss and drivetrain loss. As per the Dyno readings, the Roxor’s rear wheels in 2WD mode gets only 52 Bhp of maximum power and 180 Nm of peak torque. After the ECU tuning was done, the Roxor produces a whopping 115 Bhp of maximum power and 339 Nm of peak torque in the rear wheels. This is a massive increase in power and torque figures.

We are not sure if anyone has tried doing the same in India with the Bolero’s engine but the engine itself has the potential to produce much more power than the stock. However, ECU tuning changes a lot of things other than the power output of the vehicle. ECU, which stands of Engine Control Unit controls the way engine works. All modern vehicles come with an ECU. The ECU controls the combustion of the engine by controlling the opening and closing of the valves. It takes input from the accelerator pedal and makes the engine behave as it is supposed to.

Re-tuning the ECU means that modifying the software of the ECU with new values that causes the valve to open more and the injectors to spray more fuel, which increases the power output of the vehicle. It is basically a way of pushing the engine to its limit. It produces much more emissions than the stock ECU and also decreases the fuel efficiency by a great deal.
