Hi guys just wondering if someone could tell me the difference in the cobra fuel management systems.I looked on there sight but couldn't figure out the difference between the closed loop and the other one.The auto tune would be nice but I don't have plans to do anything more than a stage 1.So if one of the others would work good then that's my plan,just not sure which one to get.Thanks

 

Sg34 - I believe it depends on what bike you have. They seem to be model specific. Just put the auto-tune one on my '09 FLHX. What a difference!

 

One is for California models,
One is for a bike running without O2 sensors.
One is for a bike running O2 sensors.
And the last one is the Auto Tuner which I have on my 48 and love.
