Exhaust Back Pressure

Let me start by saying I'm using a livewire to monitor, and I know it's not the best, and measures in some funky units on some things. I've heard people talk about a 1:1 ratio after adjusting for atmospheric pressure. Anyone know what the livewire measures ebp in? My gauge normally reads 120-220 depending on throttle. Just want to make sure my readings are ok. Has been consistent since I got the tuner, and no issues knock on wood. Thanks for the help.

kPa (kilopascals)

I'm not sure if the Livewire reads with atmospheric pressure added in or not.

Thank you! Pretty sure that's the units of fuel rail pressure too. I've got a converter saved somewhere. Hopefully sometime in the near future I can get a decent monitor.

16 - 32 psi converted, is certainly safe even if its not adding atm pressure. What's it run at idle?

Off the top of my head, I think about 120 kpa.

120-220 Kpa= 17.4 to 31.9 PSI
