MSPNP2 not showing over 85kpa
 

I recently installed a jrsc m45 and it’s showing 4.5psi on my boost gauge but in the data log the max kpa is only 85, I need to get this figured out in order to be able to tune my fuel and timing correctly

What does the map sensor read with the engine off?

This

Does the map change when you turn the car off?

It still reads that there is pressure, I’ll check the exact numbers in the morning I didn’t realize I got a reply sorry I have it t’d into the fuel pressure regulator at the moment

fixed it thanks a lot, the trubokitty map I had was set up for a 2 bar map sensor and I have a 4 bar

Yep, when engine is off you should have about 101kpa at sea level and up slightly with altitude increases.
