Default lean or rich?

Hi …
Are these lean or rich conditions? I need clarification for this case

Both STFT show 0@WOT & Both LTFT show positive 12.52@WOT
O2 B1S1 915@WOT & B2S1 905@WOT

Thankx

your tables are lean, and the +LTRMS are adding extra fuel to make up for it. At WOT, you are a little rich, likley to do the PE tables.

If you are tuning, sounds to me like your VE table/MAF need to be fattened up by 12%, then the LTRMS' will drop.

Actually the car was tuned last week by some one and I don’t want to miss it out, because I can’t tune it my self. Therefore I ask if I have to worry about the lean tables if the car is running little rich @ WOT

Thanks

Your car may be "tuned", but it wasn't tuned very well. Yes, get you Ltrms to 0 or just slightly negative - then tune WOT.
