ok, just finished installing the headers and the widebands. Went for a little spin and man i am running lean. I am starting to wonder if it's the widebands that don't give an accurate reading or if it's really lean.
When i go WOT, it will be 14:1 from 3k to 4k rpm, then drop to 13,7 13, 5 between 4k and 5k and only at 5,5k it gets to around 13:1.
Anyone else ever experienced such lean conditions with those mods?
I have B&B headers, Borla exhaust, smooth tubes, VEC2 with stock settings (untuned).
Also, when i am at idle, my passenger side is a little more lean, it goes from 15.5 to sometimes 18, it is jumping a lot. Idle is fine but it seems lean also. Only thing that works good is at cruise, i get a good 15:1 on both bank. I will try to setup the widebands so they can work with the log in the VEC2, i am waiting for an answer from Roe to see how to set them up. I'll see if i get the same readings there.
thanks for any feedback.
