Guest Anonymous Posted October 2, 2000 Share Posted October 2, 2000 I just modified my stock fuel pressure reg. so I can adjust it, and was wondering what O2 sensor voltage at WOT I should shoot for to achieve optimum mixture. I have read that 850 to 900 mV is a number to shoot for. Thought Drewz might have experience in this area, but I'll take any insight on this one. I'm a FI newbie who's learning fast. ------------------ '71 240 '91 TBI 305,700R4 w/ shift kit Quote Link to comment Share on other sites More sharing options...
