I have a 1995 sc300 na-t on an ecumaster emu black standalone revision O. The car has recharged ac, no ac leaks anywhere, compressor is working(my tuner was able to manually turn it on using outputs through the standalone). The car was previously setup with an aristo gte ecu during its previous 2 owners, when I came into possesion of the car it was running so poorly with the gte ecu and with poorly done work I decided to let a professional take over and get it setup on a standalone, he said he wired it up exactly like he has done with every sc he has worked on before and they had no issues with the ac working, could any of the work done to get the gte ecu working be preventing my ac from now working with the standalone? My other thought is that maybe my climate control in the car is shot, the screen is about %90 dead pixels but the ac button turns green when I turn it on. Anyone had a similar experiance and what did they do to get their ac fixed, this summer heat is killing me!

I've heard that you need to use a resistor in the AC circuit for the Emu Black to work. There is a thread about it here somewhere, search for NA-T threads. But yes, it could also be something with the gte ecu as well.

After reaching out to the previous owners I have determined that when the car was first on a supra gte ecu the ac worked with no modification, then at some point for some ungodly reason they switched it to an aristo ecu and the ac no longer and they did not bother to try and get it to work so it can't be anything from the ecu mod
