i feel like im not understanding what you did. you wired the brown wire to the negative pin on the rear 02 plug? Would i even be able to do this when my rear 02 plug is being used by my flex fuel kit?

you got any pictures?


since you have the same WB gauge, what range does the ecutek numbers actually "show". Mine is 11.40-17.06 so yea something is off for me.

I might have to give up on this endeavor. I have a turbo on my setup and since splicing into the evap (CPC) input, it had disabled my EBCS. I can't go higher than wastegate pressure now.

anyone else had this problem and fixed this? i might just undo everything since its messing with my boost controller.
