need opinion on a/f wideband
 

i have a wolf3d v4 plug and play for my s4 fc. i want to get an air fuel wideband gauge,to monitor my car. will the ngk,aem,or innovate conect to the wolf to get readouts for data logging? once again i am not the most tech advance guy there is. i just need some direction in where to go. i have about 350 budget to do this . the car will be geting tuned in about a month, so i need something to be able to log and to monitor.
thanks
Tony
