i have a 2011 gsr, bone stock. i installed my cobb AP and loaded the "Stage 0 stock map" my AFR is at 20.0 at idle and cruising, is this a normal AFR? it seems very lean imo. any input on this "Stock stage 0" would be greatly appreciated

 

I'm not sure your AFR sending unit is working right? What were your AFRs before you flashed the map? I've never heard of this "stage 0" btw. But i'm an 08 so things change. 20 is full retard lean. Idle should be about 15.5 ish and part throttle around 13s. Wot in 11s. Generally.

 

i dont know what my afr was before the flash, my AP wont let me monitor without flashing. ive uninstalled it for now cause im afraid of that AFR

 

Oh ok the new APs allow AFR readings. We old 08s don't have that feature. It may just be reading wrong. There were a few issues with fuel trims and boost and maybe another data reading that were wrong on the 08s to begin with. I seriously doubt you're running 20. Get an AFR gauge and a boost gauge. Only 2 you'll need and you will know for sure what you've got. my .02

 

You aren't actually getting 20:1 AFR. The AP can not read AFR w/o a wideband o2 sensor so it's just showing the max AFR value. Flash it back on, it's safe.

 

And the voice of reason has come upon us haha. Knew there was no way that was correct. Sorry I wasn't up to date on the newest AP. My old 08 version has none of this AFR you speak of so..at least you got it figured out. Thanks for enlightening us Kracka.

 

yeah thank you!
