[QUOTE="slow poke, post: 14591174, member: 163268"] I have the base fuel table set back to what It was in the base tune, so it is NOT all 14.7 / lamba 1 like it was when I was doing the open loop tuning. This is why it is frustrating, I keep expecting the AFR to drop but it doesn't. I realize I could still be in the part of the table that is commanding 14.7 but as I get higher in the load and RPM it does not drop some I am worried about giving it too much throttle or bringing it up to say 5000rpm. I was hoping it changed with the new O2s, upon first test it doesnt seem to be any different. So I guess the wiring could be messed up but it ran fine prior and I did not change or disturb the wiring. the wires split the transmission, its highly unlikely they got swapped when I put in the new exhaust. not sure where to go from here. I guess I will drop the tank and see what fuel pumps it has (its a swapped car so I am unsure). I am hoping I find something. I just dont have enough knowledge to really figure it out and do so in a timely manner. Im learning as I go. [/QUOTE]
