Question Testing Boost Logging with Omni 4bar

Just installed my Omni 4 bar MAP Sensor and reflashed my ECU and setup ECUFlash 2.8 with the settings from:

https://www.evolutionm.net/forums/ec...o-8-9-a-2.html

Went for a cruise to see if everything went well, but I don't know what I'm looking for. For those who know more about this, does my boost chart & levels look right?

2006 Evo IX - 88590015 ROM
Only mods are an open element air filter and a turbo back exhaust right now.

Just log one 2—7k rpm pull. That hurts my eyes.

is the car tuned? was this log all from one gear? and looks like it spikes about 21 which would be right for what you have done to the car

Lol... Sorry guys... I started the datalog when I left the house and didn't stop til I got back. I'll try to filter out the graph first. If I can't get decent data, I'll go do a pull.

Ok... I finally went out for a little stroll. Here it is. 3rd gear pull but <6k cause I was running out of space.

This looks better, but is this what I can expect for stock boost levels? The reason I really want to know is that I'll be installing my boost gauge and MBC soon and I want it to be as close to stock when the MBC gets installed.

Looking at the data, I read it as:
Cruise at 2200 rpm
WOT
Takes 3 seconds after WOT to go from 0 to 19.18 psi max @ 3500 rpm
Boost tapers down to 16.33 psi @ 5750 rpm
Lift
Boost drops and goes to vac

Your MAP sensor appears to be configured correctly.
