Wonder if the issue was with the ECM or the harness. Nick did you switch one at a time or just switched everything at once?The laptop programming issue was easily solved by Cal, and we finally were able to do a road test as it was 100 degrees for the first time in over a week as it has been 110+, and no road tests are done at that temp!
Car ran ok, but shortly on the road, an error code for the O2 came up and the values were not normal?
After another hour checking the wiring with no improvement, a call to Cal he said check to see if the O2 was heating like it should, that proved to be negative.
I ordered 2 units, so it was a simple fix as the second harness and ECM was installed and the problem was solved.
Over the years many aftermarket items may have bugs like this, and I am so grateful for Cal's tech support and expertise, as well as standing behind his products!
