Hey guys, just a quick one I've noticed recently that whenever I accelerate my Z and I rev past the 4k rpm line on the tachometer my digital A/C pod shuts off and the display disappears along with the air-con system completely. Once I drop down under 4k rpm the A/C pod comes back on like normal. Is this normal at all? I have a series 2 digital A/C pod and matching amplifier (ecu). I found that it only occurs when the A/C system is not being used or if it is in the ECO mode, if I have it set to AUTO the A/C system wont shut off.
