Hi Guys/Gals,

                              I'm an old fart from the era when we had things called carburettors.  When I read this page I read an alphabet soup of "AFR" "VE" etc.  Would some kind soul who has the time put some definition to these and other standard terms?

Cheers

Thanks. What does Volumetric Efficiency mean? A measure of efficiency per volume air/ fuel?

So if I add timimg am advancing or retarding the spark?

If I take timing away am I retarding or advancing the spark?

Thanks all. Any further acronyms and what the heck they actually mean would be good.

I'm still re-reading the TTS-PC war threads...I should have kept my 2001 FXST. I'm simple, I like simple things. Like women,

  

Thanks guys.
