it looks like there is going to be no fix for dual zone any time soon or at all. matt hasn't replied to me about a fix or any more testing needed so it looks like they just cant do it. the work around I am using in my ssv(dual zone) is to source a single zone hcm out of an omega or sv6 and swap out the dual zone hcm for the single zone hcm. picture of hcm. this works perfectly for cold/ac but with the heater only the passenger side gets heat the drivers side stays cold, you can just put the passenger side on heat and close the drivers vents off using the little flow adjuster dial on each vent and the car will heat up fine even with the ac on. I don't use the heater so for me the single zone hcm fixed the problem for me as I only use cold.
