    afr and rrfpr

    Guys hello,

    Would like to learn more about afr and rrfrp. Is there any link. Suppose that i install and afr in my ski and i want to tune the ratio based on reading, how can i do it. Does the afr gauge give you the ability to do it or do i need smt else installed. Or, do you get the readings from afr and then tune the ratio with the rrfpr.Pretty rookie questions but i would like to learn more. Thanks in advance

    Yes you adjust your fuel pressure to change your AFR. More pressure = richer and less = leaner.

    Afr gauge is a good first mod. You can also look at this http://www.greenhulk.net/forums/showthread.php?t=164229 as another option versus the rrfpr.

    a 1:1 rrfpr can only do so much, like 10+% more fuel
    a begi 5:1 can give much more if your fuel pump and injectors are up to the task

    Stupid question but, what's a begi, how does it work and where do you get one?
