As expected it works on my 86 as well, albeit with slightly different behavior. For example, ACC+IGN1+IGN2 only lasts for about 5 seconds before shutting off, and the window control commands have to be fired multiple times until it fully opens/closes. And in my logger (had to dig out the other stuff) - SSM4 is doing the same thing unlike yours which the entire window goes up/down with the command is only issued once.

Also, running ACC+IGN1+IGN2 when the car alarm is armed, triggers the alarm.

My fuel cut command is slightly different from yours, but it works all the same. It was captured from Techstream though.

Since ACC+IGN1+IGN2 is initiated by the BIU (with header 750), the turn off command should be coming from there as well. I can probably use the ELM327 to monitor and find that command somehow.
Oh yea , you are right. That is 5 seconds. But for the actual live canbus broadcast message, the ecu continues to broadcast canbus message for abou t15 seconds, and the power to the window/HVAC.. (via IGN1/IGN2) will stays on for about 45 seconds.
