DESCRIPTION

EVP was first to dyno and tune the Polaris RS1. Gains come from timing, fueling, torque-limit, rev and speed limit changes. We also lower the fan-on temperature by 20 deg F and can set fan on/off temps per customer.

• Revised decel fueling to remove lean pop with aftermarket exhausts
• Raised rev limiters
• 100% throttle available
• Improved throttle response (E-Gas settings)
• Ignition timing optimized for 91 octane
• Fueling adjusted for intakes, exhausts, and cat deletes
• No piggyback fuel controller needed for most bolt-on mods (customer must ensure compatibility)
• Engine speed torque limiters removed ("Shaft Saver delete")
• Vmax delete (speed limiter removed)
