It was titled JDM MAP before I changed its name. Also, Charlotte is 751 feet so I used 14.3psi for atmospheric pressure.

Here is a good calculator, although it says I need to use 14.22psi for 751ft

Just wondering why the left column (Voltage?) goes only to 3.63V and the 2nd column has a large jump in value in the last row from 195 to 255). The data preceding it is pretty linear.

What is in the 2nd column and how is it used by the ECU?

That's right. Im using ROM 96530706 V7 as well. Installed and plugged in my Omni 4bar, made the changes to Mitsulogger and voila, I'm logging boost and almost ready for speed density! This is great! THANKS, ECU-Gurus!

Ok I installed my OMNI 4 bar and made all the changes to my 94170015 rom...it's logging boost great and I went through and disabled the egr like told.

Now my issue is that I'm running about half a point lean...would this be due to the egr disable or something else?

Can someone clear something up for me.. Im tuning a evo 7 on SD and he installed the omni4bar.. i dont see any scalings for the omni 4bar for 96530706. Is there any scalings required for this rom ID or is it not necessary due to the fact it didnt come with a MAP sensor from factory?

Thanks
Tom

how comes it just works on the 9653? is it because the 9653 came out of a car with no map sensor?

If my memory is correct, yes.
