OK, I will be doing a before and after with the ecotek valve this weekend, so I'd like to know my way around O2 sensor voltage. AFIK, 0.86 is lean, and 0.88 is rich...
Anyway I can convert these voltages to A/F ratios? What is a safe A/F or voltage on a steady 80mph cruise? What about WOT?
TIA 0.88 is by no means rich! That is very lean and 0.86V at WOT would be seriously causing some damage. Ideally for a Duratec engine. O2 voltages of ~0.935V yield the best and safest results.
