PWM cooling fan(s) control using ECM

[flyingv]

For any of you with an E67 from an 09' vehicle, here is what changes I made to finally get the C7 PWM fan to work.

1. I changed the OS from 09' CTS-V to an 09' ZR1

I did confirm through a document on the EFI Live forum that the 2 OS's are compatible.

*no matter what i did with the CTS-V calibration, I could not get a output signal from X3-49*

2. I changed fan settings to PWM Electric 100hz

*PWM EV 100hz did not work per the C7 calibration*

3. Fan State vs. Desired (all zeroes)

4. Output State vs. Control (all 1's)

5. Wired in AC pressure sensor @ X3-21, X3-57, & X3-37

Viola! PWM fan control works in the scanner!
