tunning with chrome to pass state ref
so long story short my ecu has been chipped and my ref dosnt know. i can pass the visual. so far i am running open loop so i failed by a long run. but i live in a basic area so there are no rollers its just a basic 0 to 2500 idle test. if i tune it in open loop with a decent afr gadge to a afr that will get me to pass. then in wire in the o2 and run it in closed loop will i pass for sure. ihave a brand new 50 state cat and i also need to install a iat sensor as i have a resistor in the plug as of now. i am a noob i know this if someone can direct me to some information that will answer my question i would like that too i just cant find it on my own as in tunning for emissions. im just currently studing to learn how to tune our pgmfi

Re: tunning with chrome to pass state ref
so i fixed the iat and im going to buy a chip burner so i can enable my o2. i also am going to get a aem wide band unless someone can convince me otherwise. what air fuel ratio will get me to pass 14.7? and also if i want to adjust fuel tables on chrome manually how do i know how far to bring the numbers down im having a hard time finding information on that. thank for the help.

If your engine is stock, you've wired everything correctly to the correct ecu, and you have a decent catalyst, you should be able to pass (without tuning). If your wiring is all jacked and you have a mish-mash of parts, you're going to have a tough time calibrating that out (by which I mean not likely)

If you're going to use the wideband as an O2 and you're going to run off of a chipped ECU, make sure the wideband can support simulated narrowband output. PLX is just one of the many companies that make one.
You might want to check it then. https://www.youtube.com/watch?v=VmfiI1ribdM

im guessing i should go with a wideband that supports narrow band because its more accurate in those volts? what makes it diffrent from a wide band if the wide band reads a higher voltage range.

Re: tunning with chrome to pass state ref
No. It's because your ECU isn't calibrated to the voltage output of a wideband. It's calibrated to the voltage outputs you'd normally see from a narrowband output. A narrowband only detects a small range of AFR; a wideband can detect a much wider range, hence their names. They both put out voltages from 0-5v. It's just that the voltage output from a narrowband to reflect an AFR isn't going to be the same as a wideband reflecting the same AFR.
