8l90e tutd
I'm setting up an 8L90E behind a 2016 LT1 in an older car. I would like to get the TUTD function to work. I have read other post saying that the hard wire input goes to pin 39 on the T87 controller. I have the resistor values figured out. Is there something in the TCM that needs to be switched? I have looked and don't see anything in the cal that says something like "switch TUTD from serial to hard wire".
Thanks in advance.

TUTD is a hardwired connection since CAN/serial might get busy and slow down.

There is no "switch" in the tune file to change from serial to hard wire. Is there anyway to get this added to the cal file?

Probably not sorry, too hard to locate with these TCM's.
