What afr's are you guys seeing in the 2-step? Even though I have my fuel maps set at the max 7.5 I am averaging afr's of 20.

I know arf, arf...Sorry for the typo.

 

I see very high ones as well at least in the 20 range. I have not logged it though.

 

Thats because no matter how much fuel you put in the cells, the 2-step functions by cutting the fuel as opposed to the ignition. That means that the engine is still momentarily moving air through it with out any fuel being injected therefor causing a lean mixture. A 2-step that cuts ignition would in turn make the mixture rich asuming you're not retarding the ignition and burning all the fuel up in the manifold and turbo

 

I understand that the AFRs are going to be high because of the fuel cut. I am just wondering where other people are.

 

Mine bounce around 17-20
