How do you richen up start up open loop AFR?
I see the area in HP tuners where it deals with start up AFR correction but what exactly do you have to do to richen it up?
Also, in that same section in HP tuners there is the commanded stoich AFR and it says 14.7 and when I was having problems with my car I changed that to 13.5 becasue the car was extremely lean at that time. But even though I changed that my wideband was still reading around 14.7 but my fuel trims where not nearly as lean as they were before.
After I got my car fixed my fuel trims went rich so I changed the stoich AFR back to 14.7 and then my fuel trims went lean again.
I guess my question is how come my wideband shows 14.7 eventhough I commanded a stoich of 13.5?
