Polaris Scrambler XP 1000 PCV Auto tune installation. May 27, 2015 I’m installing the power commander 5 and auto tune in my scrambler and I need to know which cylinder is #1 and which is #2 I’m assuming the front would be #1 but I’d like to make sure first. Any tips would be greatly appreciated. Share this:Click to share on Twitter (Opens in new window)Click to share on Facebook (Opens in new window) Related
