Hi, Does the A/C idle up feature work with the PRC ecu?

With the A/C on input I'm getting the idle up, but E18 refuses to ground the compressor relay. When I change the setup back everything works fine (well except for the idle up). So I tried, "Y" the A/C input and compressor relay ground, and that kinda works, but the load of the compressor is too high and idle dies.

From the Help file: Normally the AC on signal is sent to the ECU via the multiplex communication bus. For vehicles which do not have the multiplexer, it is possible to use the VTP input as an alternate AC switch input. Note that the multiplexor and VTEC pressure check should both be disabled. The normal ECU AC clutch output is used.

Yes I've all that, It just does not seem to work. for example, E18 Should be 12volts with compressor off, I'm getting 0.02volts on or off. but the compressor does not switch the relay.Maybe I'll upload my hook up?
