Subject: Re: air fuel ratio guage by dan0617 on 2011/11/16 12:01:30 It is best to have all 3....but when you make a run you will be focused on the road or track, and watching the AFR gauge as much as possible. If you lose fuel pressure you will more than likely see the AFR gauge go lean and let off of it, well before your eyes see the fuel pressure gauge go down. So, the AFR gauge will show if the fuel pressure drops, but the fuel pressure won't always show you if it goes lean for some reason other than fuel pressure. |
