MPA pressure sensor calibration

Post by BESM »

I want to set up the pressure sensor so that it has the same characteristics as the OEM stock vacuum advance module.
To do this I would like to know the actual pressures associated with each bin so I can match the advance to the vacuum value.
Even better, can one set the pressure in each bin and then input the desired advance?

I am confused by the illustrations showing gauge readings up to 255 kPa which is far in excess of typical maximum vacuum of about 60 kPa

I have ordered a Megajolt and it should be here in a few days so I can't do any practical work just yet - just thinking ahead.

Thanks

Further to my last post, I now realize that the pressure sensor reads absolute pressure.
Anyway I would still like to know the mapping of teh pressure to teh bins

OK I think I have it now.
I can edit the load bins to get the pressures I want
