I bought a sunpro narrowband gauge the other day. BUT it's giving me problems. If I hook it up it will NOT sweep. I do not know why? I pulled up a diagram and it said it was the white wire so I tried that. But of course I didn’t work then I tried the other 3 still will not sweep? WTF anyway I got a new gauge thinking it was bad yet again still the same thing. And the o2 is brand new also I stuck the gauge on my friend turbo Eclipse and it worked just fine? If anyone has any idea's please let me know. As I am lost

 

whats the point of this? A narrowband o2 is worthless. You just wasted money and now time trying to install it. If you want to monitor your engine, get a wideband and get real a/f numbers

hell, you could of just got a apexi TT and taped into the stock reading and got the same bad readings

 

The point of the narrow band was as a secondary safty. Since it is my dd it will let me know if the o2 is going bad. also if the wideband would go. Im not dumb im not going to use it to tune. Plus is not like it was a lot maybe 20$.

 

A narrow band 02 gauge is like a Fire place simulator. Sure it might look cool, but ummm, its doing nothing.

$20 wasted either way you look at it.
