hookd up my afr n n2o guages last week and runnin N/A the guage goes from first red led to last yellow led n bak n forth while under throttle, under WOT it holds in the green (im pretty sure thats good, right?) and at idle i get no reading then itll bounce into the yellow? is this all normal??????!!!!!!?? HELP

 

If it's a narrowband o2 gauge thats normal, it'll jump all over the place when cruising. I wouldnt trust it for nitrous use, the narrowband o2 sensors are only supposed to beaccurate around 14.7 afr .

 

it's just the standard autometer 2 1/16th carbon fiber guage

 

if your not running a wideband to that guage you are only reading the narrowband 02's so thats common. but if you get the lc-1 you can calibrate it to give you a accurate reading with that guage.

 

sorry to tell ya this buddy, but all you have is a nice "light show"

its not a "true" AFR gauge b/c its a narrow band.

do some research. If you want a real A/F gauge you need to buy a wideband.

 

formula8r you can use this guage to read a accurate a/f reading only if you get a wideband like the lc1, you would need to calibrate the lc1 to work with your autometer guage. right now your just reading a narrowband reading which basically reads your o2 voltage so its going to bounce around alot.
here is a link to the lc1 which will work with your autometer guage to give you a correct a/f reading with your guage. http://www.dynotunenitrous.com/store...?idproduct=151
