This might be a stupid question and if it is I am sorry ahead of time. However I just ordered a boost guage and air/fuel gauge. Now they say the air/fuel only works with a "narrow band o2 sensor". I have a stock 90 GSX, so do they have a narrow band o2 sensor stock or not.

Thanks
 
yes just tap into the wire of the o2 ... search it up if you dont know which wire...

although, why get a narrowband ?
 
Evood69, If you have the cash I would send back the a/f gauge and get a wideband kit. The light show does not help at all. I bought a car with it, and it does nothing but have pretty red, orange, and green lights!! LOL If you do not have a datalogger, get one. It helps out a lot!
 
The narrow band gauge only reads 0-1 volts and its very crazy and most likely a light show and wont help you what so ever. Now a "wideband" reads 0-5 volts and gives you a direct reading like 14.7 afr. So you probably spent 50 bucks on a useless gauge and another 150 dollars could of yielded something useful.
 
I appreciate all the helpful information, I will send it back and get my money back and go with a wideband. Any suugestions on widebands from personal experience?

Thanks

AEM UEGO widebands are in my opinion the best.
 
I would go innovative LC-1 I had both and the LC-1 was better and the same price as the uego.
