[Land-speed] EFI AFR Question..

[drmayf]

Well, it's dark out now, so I won't go look, lol. The one I have is 
Innovate LC-1 system. Is that good or just average or poor.  Iguess the 
question I was asking was what's good enough. If I command 11.5 and get 
11.4 how much time do I spend trying to determine if it is sensor, or 
real live afr? What's the cost benefit analysis gonna say? I could spend 
a zillion bucks tracking down something that is in reality in the noise. 
What do the rest of you folks who tune with a wide band do? How close is 
close enough?

Oh, Dave, how much for the Accel DFI 77030-3 system for a mustang? I 
need tostart saving my milk money..
