Oil Pressure Issues

IronBird · April 11, 2025, 9:55pm

I’m having trouble getting my oil pressure gauge to read correctly. I’m running a GM E38 ECM (gen 4 LS). The value shows correctly on the debug screen, but it reads about 14 times too high on the gauge (although not a conversion factor).

I also can’t import the Ethanol %, but that doesn’t show up on the debug screen at all.

Any ideas?

Your Oil Pressure:

units="kpa" conversion="V*0.578+0.06894757"

RealDash expects Oli Pressure to come in as BAR. Then it is converted to psi or kpa based on the app settings. Modify your conversion to make oil pressure to BAR and it should work fine.
