ok put two new oem O2 sensors in and i'm in way better shape as far as closed loop goes. car was driving like crap and smelling terrible. it has gotten about 20 degrees warmer so my open loop afr isn't as rich. next step is to log the car and tune the ve tables. also have to do some fine tuning on my idle through 2500 rpm timing .

I am new to tuning, but I do have the CSI video, and it makes correcting the MAF tables look easy, and VERY critical. Is this actually mis-leading?

ok so i plotted my BLMs vs RPM and I'm seeing I have still have splits which sucks. this graph is of just normal driving. my major concern is the left side. at the higher rpms the short terms on the left side are way too lean while the right is on point. anybody have any ideas? the bottom is a percentage and the top are the actual counts.
