TURBOTRONICS

I think my maps sensor if giving the wrong reading because I get fuel cut at about .6 bar
Dose any one know what voltage to pressure ratio I should be getting
I.e. .5 bar = 3 volts or 1 bar = 5 volts if you get what I mean
I have had to make my own fuel cut defender to stop this but it’s only effective up .9 bar
Thanks

TURBOTRONICS

Sorry Scott I don’t understand
I was hoping to put my multi meter across the terminals on the ecu and read the voltage while using a large syringe to create the pressure and see if the voltage matched up if this is possible that is

yep, just look at the last 2 columns. they show the readings
