N55 3.5 Bar issue *PLEASE HELP*

[SilveraA]

I am trying to tune my own car and from what I gathered its working great but I've just upgraded turbo and also bought 3.5 bar sensor. My issue is that I want to run 24-25 psi but even if I set load to 220 I can't run above 22.6. I assume I need to not click the 3.5 checkmark on MHD but how do I make the sensor read up to 36 psi ?

I don't want to use JB4 but I think that is the only option I have left

I'm not sure on the N55, but the 3.5 check box I thought was for JB4 only or something. The scaling needs to be done on your end in the tune. This is really really rusty info though, hopefully that points you in the right direct.

Someone else feel free to chime in if that is not correct.

Yeah I figured on the scaling part but I found nothing online. It’s really cat and mouse thing. I thought this was my best bet to find any kind of information

When you Install a 3.5Bar tmap, you need to change the MHD tune to 3.5Bar readings, or if you have JB4 you set MHD to normal 2.5Bar and change JB4 to 3.5Bar.

That is the issue, I don't know what to change exactly. That is what I am asking.

Are you running mhd?

Are you running mhd?

Yup

Checking the 3.5 tmap option in mhd is all you need to do.
