A Fast XFI stumper

[moose102]

I have an older (07) Fast 2.0 which powers a 4.1 with good can roller lifters and rockers, aluminum heads, etc. I have a problem with my CTS and ATS not tracing the RAW voltage from the sensors. I have verified the sensors are working, tested vIf i have 2.33 on the RAW cts the voltage on C-23, which is the CTS input voltage and it was 3.10 at the time but my cts graph read 2 Deg F, the X&Y axis was on the lowest setting. If I reverse the graph my fans com on like it was hot. I have tried adjusting the Bias many times but it did not change the graph voltage. I called FAST this AM and the person suggested deleting my current 2.05 program and reload it. I did that twice and it's still the same. When I look at the RAW voltage it looks fine and should be registering onto the CTS graph.
