Jan 29, 18 - Reviewing for the Racing Season – Air/fuel ratio

If you're getting ready for the upcoming racing season, you might be looking over your current setup to see where you can improve. Over the next couple of months I'll be reposting articles we've written in the past that can help you do that.

The basis for our online mech fuel injection jetting calculators is air/fuel ratio. It's a concept that is used in electronic fuel injection as well as many other engine tuning applications. We wrote an article about it a couple of months ago. Read that over if you want to review the basics.
