Frequently Asked Questions
What does an ECU remap do on the Polaris Sportsman 570 Gasoline 45hp?
An ECU remap (chiptuning) modifies the engine control unit software to optimise parameters like injection timing, turbo boost pressure and fuel delivery. On the 570 Gasoline 45hp, this typically results in more power, better throttle response and improved fuel efficiency at part load.
How much power gain is possible with Stage 1 on the 570 Gasoline 45hp?
Stage 1 brings the 570 Gasoline 45hp from 45 PS to 52 PS — a gain of +7 PS. No hardware modifications are required, making it the most popular and cost-effective tuning option.
Is chiptuning reversible on the Polaris Sportsman?
Yes. We always save the original ECU file before applying any remap. The tuning can be fully reversed to factory settings at any time.
