RomRaider

Hello,

I installed an Omni 3bar MAP sensor on my Ej207 engine (sti 7) and set in the Carberry 4.2 Multiplier map = 9.119 psia/V and Offset = +0.164 psia.

It is impossible for me to exceed 2.5bar absolute turbo pressure when I log a session, use ecuedit and Romraider logger.

My question is, is it possible to log a turbo pressure above 2.5bar absolute?

it's definitely possible to read over 1.5 bar relative, are you sure your reading the right parameter? there's a few different manifold pressure ones and some are limited to 18psi/1.25barish so depending on your atmo readings you could be limited there. Maybe post a log?

Thank you for your answer.
I use the absolute manifold pressure. I have also tested with Manifold Absolute Pressure (direct) same problem

Sounds like your doing it right, not sure why you're not able to get more than that, unless the vehicle is limiting itself somehow mechanically.

What's your wastegate duty while trying to pass 1.5 bar of boost? Are you maxxed out and potentially it's a problem with boost control? What's your boost control setup?

On my turbo cabin pressure gauge, I am at 1.7bar relative so the pressure is the right one.

Nevertheless I dismantled the MAP sensor and I installed a pressure gauge ( tire inflator) directly on the Omni sensor and pass 2.55bar absolute plus nothing moves on the program.
