So ya know ..... CDT does not use a pressure transducer which interfaces with the electronics. MCT does use the pressure transducer and has a much more even power delivery as HPA tank changes in available pressure.
"M" being MAP is the term used where the electronics have a map that pending pressure at given sampling points alters the solenoid strike energy so the power output stays even.
Your "C" version gun will have a bell curve just like any other UNREGULATED pcp. This curve will shift position in the Ideal fill pressure based upon what power level your using.
i personally own a MCT that is very early and has BOTH an analog gauge and electric display showing tank pressure.
