I just finished swapping a LSA and a 4l80e into a 70 Chevelle using an E67 and a T42. The harness was originally made for a 6L80e, so I got a conversion harness from Dave (DSX Tuning). The car runs and shifts great, but I do not get a speed reading in the scanner while logging. I am trying to get the speedo in the car to work, and this is the first hurdle.

Here is the the tune file. Any thoughts?

Thanks.
