I know that a vehicle trys to run at 14.7:1 but how do I calculate what the instant fuel to air ratio is? Can i use the 14.7*LTFT or something?? Any help would be great! thanks
Ok lets say I have a wideband O2 sensor.... what pid's and calculations do I have to make?
Also, I have a 2006 nissan titan, how do i know if i have a wideband o2 sensor and if I dont can I just get some and throw them in there?
Wideband O2 sensor value isn't part of the standardized OBD2 pid values. If your vehicle comes equipped with this, then perhaps you might be able to use manufacturer specific OBD requests to get this value via an interface like the mongoose, but it's not something that is documented anywhere on the internet. The manufacturers tend to keep people from posting this information.
If you really care, you can purchase a wideband o2 sensor and controller for about $200.
Zeitronix ZT-2, or Innovate LC-1 and be done.
go with the Innovate LC-1 im running one with my aftermarket fuel injction it has a lot of nice options
