In that PDF there is a transfer function given.
AFR = 2.375(V) + 7.3125
Is there no way to utilize this in the ADX?

So what you are telling me is that this 30-0300 can not be used with any ADX?

I purchased the new AEM wideband model 03-0300. The 5volt analog out put is calibrated from 8.5 to 18.00 afr rather than the older gauges 10 to 20 afr.
Is there any way to change the the values so...
