Hey guys i was just wondering what most of you are running for an A/F ratio,
Im going to get some dyno time soon and i want to get the most out of my E manage

 

I am running around 11.1-2 to be safe on my car for now 93oct 20 psi. But it also depends on the type of gas you are using, and the amount of boost you are jamming into the engine. Also it is very good to know if the engine is having any knocking issues if you lean it out to far.

 

Yep on my consertive map I target 11.1 afr (93 oct) 20 psi and reach them right at in the lower to mid 3krpm area then leveling off then race gas I target 12.1 afr (110 oct) psi varies but above 20 most of the time. Just a general idea for you but I still have some safty room and I never get any sign of knock.

 

Here's my recent A/F from a Motec Wideband done on a 3rd gear pull...AIR/FUEL VIDEO

You tell me what it is Looks really rich in the upper RPMs

 

You are actually leaner in the mid range, mine hits 11.1 + or - .2 and stays throught the powerband. From the sound of it you were at it about 5-6 grand but I don't know that for sure that is just what it sounded like. Thats not necessarly a bad thing though just speaking for compairson wise.
