I have cruising and idle afr's around stoich, but when I am around any rpm and step on the gas it goes off the chart lean. The funny thing is I am throwing a code forrunning to rich?? I am beginning to think my tune is a disaster. What should happen when you step on the gas and should the tune be richer then that ???

 

if you hit WOT it should go straight to rich then go inbetween 11.5-12.2. Im turbo though.

 

I've got a big turbo and just got it tuned. I'm not worried about my WOT tune. But I like to drive the car outside of that range and that is where the issues are.

 

if it only stays lean for a second or 2 you are alright. If your running lean then throwing a code maybe your map sensor is picking up boost and throwing it into safe mode thats what my car was doing under load partial throttle building full boost.

 

I've got it clamped at 2.6 it can't see and boost. I am throwing a code for running rich though p0172. Makes no sense. I think my tuner sucked. I need to go full ems and skip this piggy-back shit.

 

me too! just don't blow it up

 

What gage are you using?

 

Its a brand new autometer AFR. I picked it up at summit racing so I know its not ebay junk piece. I may switch back to my old map and see what the afr's look like there.

 

you havent even told us what kind of AFRs you're running yet....

 

I hope that Autometer Gauge is a Wideband...
