I spoke with a Tech at SCT today and apparently there was a batch of the newer XCal2's (devices with the BLUE backlit screen) that had the internal analog calibration altered slightly. The same wires that Chris mentioned in the other thread are the correct wires for me. But not all 9-Pin Mini-Din cables are the same. Different manufacturers will have different colored insulation on the wires. The wire colors used in the instructions on Innovates website did not work for me.
When I set-up the LC-1 and LiveLink to just log volts (to see if there was a ground offset), it was reading 0.5XXX. I had the LC-1 set-up to only give off 2.5V, so this threw me for a loop initially. Chris came over last night and we tried his XCal2 and everything worked perfectly. But his is an older one with the original calibration. The SCT Tech told me about the 0.5XXX voltage reading before I ever said anything about it. Then after I confirmed what he said, he told me about the issue with the newer devices.
The default analog equation in LiveLink for the Innovate LC-1 is (v*3)+7.35. With the different calibration in my device, I have to multiply the voltage multiplier by 4.43 to get the proper equation. 3 X 4.43 = 13.29. So I need to use (v*13.29)+7.35 instead.
For anyone with an XCal2 that has a BLUE backlit screen and has yet to try and datalog A/F with it, copy this equation and it may save you some headaches later on. But try the original default equation in LiveLink first to see if it works.
