afr w/o wideband, only nose :-) Anyone scaled their IFR table for a rich condition? How much?
No wideband here, but i multiplied all values (3.13) by 110%, and I can still smell a rich mixture coming out of my exhaust. Also, all PE values were decreased by 90%.
Is there any factors I'm over looking? Certain tables that correlate exc.?
When logging, I usually see 950mv's soo I probably have some room to play around with values.
Gonna run some logs tonight. Just wanted to attempt to get my afr somewhat better than stock tune w/ headers.
Thanks,
Kyle

Then you are not running rich, the computer is correcting just fine at idle. I have found that even with turbos if the IFR table is correct the car will maintain a 13:1 AFR with the stock AFR table. Without a wideband I would not go leaner than the stock PE table, no matter what the o2 sensors say. You might make more power but not for long.
