I'm new at the whole FI tuning. If I get a Utec would I still need a wideband? A member on the forums has a Utec and AEM wideband which enables him to display his readings on the stock navi screen. I'm thinking about doing the same thing but getting a Zeitronix wideband instead of the AEM. I like the Zeitronix screen, because I can hide it easily and I can temporarily the use it to monitor my readings until I buy some gauges. So is the Zeitronix compatible with the Utec? And is a wideband necessary?

 

a wideband will be necessary if you would like to street-tune your car. if you have it tuned on a dyno you won't need it. but you'll want a wideband....
