LS1Edit not reading
We ordered Edit for an escalade last year. The third box they sent us finally worked.
We do this with a special cable where PCM is out of the truck, tuned on the bench.
We were using a benchtop harness for the Escalade we were working with. It just wouldn't connect to upload nor download. But a Tech2 could connect to the PCM using the benchtop harness.
