Re: EEV open 260%
Is the valve open in percentage terms (%) or is it in pulse steps?

Re: EEV open 260%
The joys of electronics.
The processor is possibly looking at suction Pressure and coil temperatures and a dozen other things and is indicating % of valve rated capacity, particually on pull down.
