I just got my car back from getting its single upgrade and I noticed that the 02 isnt hooked up. The car runs fine, idles great, gets decent fuel economy (17-20 beating on it). Will it hurt anything with it not having the 02's plugged in? I looked at the dyno chart AFR's and they are 11.8 all the way across. Its stock ECU with an SAFC2, JDM 440's, and running 16psi on wastegate spring. I dont know if it makes a difference but its in an Automatic Sc300 also.
