added efans, running two fans single stage. as soon as i start the engine the fans come on no matter the temp of engine, ac on or off. i can turn them off via scanner control. ive tried changing ac pressure on/off to 0 and 500 with no change, logging ac voltage is 0 at all times. tried different ac enable/ disable speeds, but no change. fans on as soon as engine starts, not on with key on. tahoe 454 sdwb tuning 11.11.hptidle.hpl
