Dead time. Something seems wrong

Post by maych87 »

Hi

I noticed today that my actual dead time seems off. I have my car set up sequential injection and my dead time is set at .765 @ 13.2 volts. i Am using curve 1 so from the way i read it the higher the voltage the smaller the dead time should be. My car is fairly steady around 13.6 to 13.8v so i expect a dead time of less than .765. At 13.6 v I am getting a dead time of 1.039 which is higher than my dead time at 13.2v. I am reading that from the fuel calculation summary gauges under fuel settings. Is there something that I am misinterpreting or is there a problem somewhere. Attached is my msq

Air cooled porsche that’s a cylinder head temp. That’s normal.
