Please DO NOT Post In The General Section
From this point on until otherwise briefed, posting in the general section of Performance Tech is prohibited. The only thing to remain here will be the stickies. We would just delete this section, but that would cause unintended results.
The majority of the threads created can appropriately be placed in one of the Performance Tech sub-forums or Technical; and the posting of them here is detrimental to the activity of said forums. If you have any questions about where you need to place your thread PM me or one of the other mods.
For the most part you all have caught on without this post, but there have been a few habitual offenders that forced me to say this.
Everyone will get a couple of warnings from here on out, after that I just start deleting threads.
Again if you have any questions, PM me or one of the other mods.

A lower number means a you are going rich, but under boost, you dont really want to see an afr over 12.5 most of the time, and generally speaking. There are times when people run beyond this, but under boost, it becomes somewhat risky.
Remember, it is Air to Fuel Ration, so a lower number means you have less air than fuel and a higher number means you have more air than fuel.
Also, each type of fuel, gasoline, methanol, etc, has a different stoichiometric reading, so when you switch fuel types, these numbers change.
But that is a whole 'nother lesson kiddos.
F it, here is a free lesson from your good friends at wikipedia.
Fuel
Gasoline 14.7 : 1
Natural Gas 17.2 : 1
Propane (LP) 15.5 : 1
Ethanol 9 : 1
Methanol 6.4 : 1
Hydrogen 34 : 1
Diesel 14.6 : 12010 Taurus SHO - Livernois Goodies
