I know this was an old post but hoping you can help.
I have an '08 Silverado - stock E38, T42 and harness.
The motor has been swapped to a stroked LY6. So, to support that, I had a "4l60e" built from the ground up, with 300mm upgrade. Well, turns out the builder didn't quite factor that I have an '08, so, as you know, my management system is looking for the ISS input. He built me a trans. without that provision(s)...so, here I am with a truck that HAD a stock 4l60e with ISS and now with the new motor and transmission, the computer is not seeing the signal, for obvious reasons. My question can you program the E38/T42 setup to "ignore" the ISS demand? Attached are the most recent files ive logged for the tuner I have been working with.
