okay, so i did search and i have looked at ecuflash and i've done a ton of research with no luck..

does anyone know if you can put a false 2nd o2 sensor reading in for emissions purposes with ecuflash? if not, how else can you do it? i know it can be done with mechanical CEL fixes and the such and it can be done thru the ecu but i'm more curious if you can change something to have ecuflash do the same thing..

thanks in advance
