Keeping it in the correct sequence and working well is not. If you are talking about creating a tq map to provide the factory tcu with the correct info then you are back to CAN integration and a lot of dyno work to provide an accurate tq map. Then receiving can data to perform your tq reduction. All doable but not a simple piggy back is all.
If you need any info I might be able to help.
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.
