In general Nissan ecu maps suck, so you just wanna make sure it is around 12.5 or 12 and you would be much safer. Rather safe than buy a new motor.

Yea I agree, it's just to lean for me. I ordered a fpr monday. should be here by next week at the latest. I'm just gonna stay out of it untill then. Turning the fuel pressure up should hopefully get me into the 12's a/f wise and with some race fuel in there that should be safe... far as the install goes it's a external wideband no hook up to the maf or anything. it's a wideband not a narrow band. has it's own sensor and all.... Thanks for the post bro.
