i have a 06 raptor 700 and am looking at a hmf exhaust on ebay that comes with a dobech tfi fuel programmer and i im nervous ill set it wrong and mess something up! is this device idiot proof? if not what unit is? i also heard you can go to a yamaha dealer and have the computer programmed there for $30 bucks, anybody do that?

 

The Dobeck TFI is very simple to install and even easier to adjust. No EFI controller is idiot proof but they are a lot easier than jetting carbs. HMF has instructions for the TFI on their website.......www.hmfengineering.com
