Installed my omni 4 bar today.

I have an evo ix with rom Internal ID: 88590013

I have followed every step on the site to make sure everything is installed correctly.

I am posting a picture here showing that the highlighted values I am not able to manually change to the ones posted under the "how to setup omni scaling thread'

The map sensor is only reading up to 20psi.

My gauge is reading 28, and I'm 100% sure I RUN 27-28psi.

I switched my map sensor to my buddys working map sensor off his car and it's still doing the same thing.

Any idea?

I have a similar problem. Mine reads that I'm running 30 lbs but I know that I'm actually at 24. I think the altitude needs set but I would also like to know.

What Gauge do you have?

I have the stock MR gauges. I have also tried someone elses gauge. Same thing.

Did you add the required lines in EvoScan and change the formula for your local pressure? If not that would be why the reading is off.

Stock Gauges might be calibrated to work with the stock 1 bar Map. I am not sure, but
I just installed my OP 4 Bar MAP with my 0011 rom (05 MR) and it reads as perfect as my AEM gauge which has a 3.5 bar map of its own.

But do make sure you have the scaling for your Atm Press as the others have stated.
