I have one for my 07. They may be plug and play for some. They can make up for some issues with your not perfect maintenance but you quad shall be in tip top shape. If you do get one don't leave home without you oem ecu. For the geeks out there their is a live tuner that you can change values at will to get the most out of the copperhead.
I lost all my computer stuff with a crash. However I took notes on old fashion paper and clip board. Many tweaks to get the most out of my one owner 07. Used quads will have to be examined for issues before the copperhead is attempted.
Customer support is available with the tech support. There are many updates available through the VDI file. That is what I lost and has to be rebooted if I want to make changes. My map cannot be examined with out the old lost vdi file.
My copperhead rips with a tune made by a blind guy (king quad 700) that we shared.
