Hello,

I just finished installing my Prosport digital air fuel ratio gauge. I am about to hook it up to my LC-1 wideband analog output... but I have lost the Prosport documentation (was working at my buddy's house, long story...). I need to know the Prosport's A/F ratio vs. input voltage so I can program the LC-1 output. Anyone have this calibration?

Thanks!!

ill try and get this info but I would call prosport directly as im sure they know it...

I found the calibration:

0V = 20 AFR
1V = 10 AFR

Now that I have the LC-1 programmed to match the Prosport, things are working pretty well, except I have noticed two things:

1) The resolution of the Prosport gauge is 0.5 AFR point which seems coarse.
2) The battery volt function has turned on randomly a couple times. (The gauge is supposed to display battery volts for a little while when you first start your engine and the wideband is warming up which is a cool feature, but a couple times after driving for a few minutes and the gauge displaying AFR, it reverts to battery volts ... annoying!)

hello i also have some questions on this. I just installed my prosport afr wideband gauge. When i purchased the car it already had the LC-1. So I found the directions to wire them together online and did so. My problem is that my gauge just keeps reading the volt even if i turn that feature off. When the volt function is on the guage reads the volts (even after the 50 sec wait period) even after the volt light goes out and the colored bar that is suppose to move just stays at optimal and never moves. When the volt feature is off the bar stays full rich.

Does anyone know what the problem is and how i can fix it?
