Here's what Ive came to understand. Timing is pulled at shifts based on output expectations (in a fairly linear fashion probably from -5* to -25* based on what im logging, and my logging parameters aren't very efficient) whatever information being sent over CAN between the ecu and tcu really isn't expected to be pertinent to mimicking the ability to pull timing upon shifting, if I can read shift solenoid Voltage or activation, ill simply have to add a secondary microcontroller coded to say when solenoids engage to shift up, send a signal to the secondary ecu to pull power on a axis setup based on load. Can integration isn't capable currently with haltech elite for the end user (yet), and honestly i don't have enough experience reverse engineering CAN to really be successful at it, as well as it is very time consuming.

I have thought about it many times. Still consider a Renntech stage one every now and then. It's good to see homeboys on the forum. I'm a few towns south and one or two east, where the boys play ball inside in the winter and outside in the summer.
