    I connected up the LC-1 Yellow to the VEC-3. It's coming in on Analog-3 instead of Analog-4. Did I get the wrong connector pin?

    Also, I'm not sure I'm getting the correct A/F reading from the VEC. When I run a log with the engine off, I get an A/F reading from the VEC3 of ~13. I would think it would be maxed out at the 22, that the LC-1 can go to. How can I get a baseline reading that I can trust?

    A snapshot from my log runs are in my other post, and the RPM's aren't showing up correct either.

    You should use analog in #2 on the master and/or slave for a gen I .You need to go into the LC-1 program and set the correct parameters so the vec will read it properly.Can't remember the #'s of the top of my head,but someone can chime in with them or just call Sean! :2tu::usa:
