The 300zx/Wolf ecu doesn't properly control the 280zx aac valve. Even if it did, the stock 280zx idle control system uses non intercooler air for idle control. Your source of air for idle control should come from the intercooler outlet, not the turbo compressor inlet or outlet(the stock 280zx use the compressor outlet because it was designed for low boost, non intercooled situations).
If the idle control is improperly hooked up, you may be causing a boost leak, allowing air to be recycled and reheated by the turbo. In another case, you may be allowing some compressed, uncooled air to bypass the intercooler. Either case is trouble for engine and the turbo. Not only could you have detonation, but you could be over spooling your turbo.
