Hi

I'm running an M84 with C125 dash.

Getting strange reading for fuel pressure in psi on dash says pressure only 5-7 on prime up (actual pressure is 45-50psi)

I have the unit in dash set to psi but its like its reading the pressure in psi as a kpa reading then converting (again) to psi

I have tried setting up a new file using M84 template but same result.

Really strange thing is that it used to show correctly and to my knowledge we haven't changed anything ?

Is there a setting in the M84 I need to change ?

thanks
Wade

Hi Wade,

The dash assumes you are sending the channel in kPa so that is why you are getting the wrong value. You have two options either change the M84 to use kPa, which is the easiest option or modify the CAN template in the C125 to convert from PSI to kPa.
