Welcome to Episode #2 of Snow Bike Nation

This was one of the most fun and exciting interviews I’ve had the pleasure of conducting. Jeff Peinhart, co-founder of PR2 racing has an extensive motorcycle and engineering background. PR2 provides one of the best ECU’s for fuel injected bikes and developed of the first snow bike specific ECU maps.

Here’s a bit more about PR2 from their website

PR2’s ECU maps have helped win multiple supercross and motorcross titles.

From the likes of

  • Eli Tomac – who rides for Kawasaki and has won multiple supercross and motocross championships.
  • Ryan Dungey – 4 time supercross and 3 time motocross champion
  • Broc Hepler AKA ” “The World’s Fastest College Student,- first rider they built for.

Along with 20-30 other top riders

Timbersled approached PR2 in 2013 to providing the tuning on the ECU for them.

We’re gonna discuss how and why he designed the mapping for the ECU’s, why it’s so crucial if you have a fuel injected bike to have one for optimal riding of your snow bike.

We discuss new products released for the Snow biking community. Like widening of the throttle body for an increase in horsepower.

A few key takeaways we discuss:

  • Jeff discusses how the loading of the engine is so different on a snow bike than what it was originally meant for.
  • Stock ECU does not handle the application very well. Really needs to build the mapping structure for them to run optimally.
  • At 53 min Jeff talks about the best way to adjust the fuel on his ECU.
  • How some pull 2 gears higher with their ecu.
  • How changing fuel injection timing because of the cold / deep powder is crucial for optimal performance.
  • How you can increase your Horsepower with widening of the throttle body which PR2 handles!
