[Land-speed] EFI AFR Question..

[drmayf]

Taking a moment or two and just browsing data. Since I am still learning 
about EFI, can I ask a question? Ok here it is. If my brain box commands 
a specific AFR number and then computes the injector pulse width to 
meter the fuel to meet that AFR, and then my wide band tells me what the 
actual AFR comes out to be, just how close should it be to be considered 
to be good and accurate? Like if I tell it 11.5 and it comes back 11.2 
or 11.8 or something. Just how far off can it be and still be 
acceptable.  1 decimal place? 2? 3? Does any of that make sense?

just curious and as I said still learning..
