Our new piggy-back style Fuel Programmer is the best overall choice for adding the proper amount of fuel to your 500/501. You leave your O2 sensor hooked up and the use of the Programmer does not throw codes.


We have spent a lot of time on the Dyno with the Air/Fuel meter, designing the base settings in this unit so you can just plug and play.


This is also a one of a kind programmer that includes an adjustable “accelerator pump circuit” which isn’t available anywhere else in the world. This allows you to play with the settings to give your bike a “fuel spike” for when you crack the gas quickly. This removes lag and flameouts when you need to get up and go quickly.


All you have to do is attach our Fuel Programmer to the bike, use the settings we’ve already set for you (or play with them within a range as you like), and your bike will be forever changed. It covers your fuel ratio and acceleration programming needs whether your bike is stock, has only opened up exhaust, or has opened exhaust AND intake!


Tampering with the ground wire voids the warranty
