hey - got an ek with older hasport adapter harness & k20a-R swap (hytech header, RBC, 3" kteller/burns, PR stack & IMG)
o2 sensor was reading constant 25 a/f when actual was 12-13... made adj & did not change. we then to sensor on other k-swap'd car & read fine
what do you think? send adapter harness back to hasport w/sensor???
thanks
