I have my Wideband sensor in the driver side greddy downpipe. I get an af of 15:1-14.2:1 while driving/crusing. If I get on the throttle, but only to the point where the turbo is about to spool (0 vac, atmospheric on the boost gauge) my af hits ~12:1 by 6000 RPM. At 1 psi + I see about 11.2:1 all the way to redline. What are you guys getting?

 

Not sure what your trying to find out , but...what ever you are using to control your system [correct me if Im wrong ] will adjust you A/F with rpm's OR boost .Meanig you can raise rmp's to 6,000 with out getting any boost and the A/F will adjust just as if you were at 6,000 rpm's and 6lb's of boost .The SS box with the Vortech SC does this also

 

Ummm. What the hell are you talking about? NEXT!

 

made sense to me.

I think he is asking what you are using to control fuel - and if its rpm or load dependant? I assume since its a GReddy kit, its a Emanage.

Might also help people to mention what type of AFR gauge/sensor you are using

 

I have a Tech Edge WBO2 and am not using e-Mange, using an auxillary Aeromotive pump and DFMU. Under boost at any rpm, the afr drops to 11.7 to 12.1. At full boost it is 11.8. 12.1 is where it reads when boost first starts.

At 0 vac and 6,000 rpms, I am around 12.8 to 13.2.

 

Of what sence I could make had nothing to do with the proposed question. The question is what are you AF readings under boost and while crusing. Nothing to do with how you control it.

 

well my car runs at 14.7:1 at cruise then when i gun it i cannot even read the A/F cause it is SO FAT........just three little dashes like this.........---......Someday i will tune her to 11.8:1 A/F and put down 400rwhp. Someday........
