05v analog output data logging

[94TBI]

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 that the dash board will read accurate afr data?
Thanks in advance to anyone that responds

The attached .pdf does not show that the 30-0300 has a programable AFR range.

The attached .pdf shows the 30-0300 has an AFR range of 8.0 : 1 ~ 20.0 : 1

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

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?

Possibly the 30-0300 can be used with any ADX, with the correct conversion?

Information from the link in post #2:

For the LC-1 WideBand 0V = 7.35 AFR and 5V = 22.39 AFR.
AFR of 7.35 to 22.39 is a difference of 15.04 divided by 1024 = 0.0146875

Conversion for this would be:
(X * 0.0146875) + 7.350000

Adding the offset makes 0 volts 7.35 AFR

For other Wide Band controllers that have 0V = 10.00 AFR and 5V = 20.00 AFR.
AFR of 10.00 to 20.00 is a difference of 10.00 divided by 1024 = 0.009765625

Conversion for this would be:
(X * 0.009765625) + 10.00000

Adding the offset makes 0 volts 10.00 AFR
