Omni 4bar map sensor Plug and Play
Im using 0.19347*x-14.3 in evoscan I am about 750-800 ft above sea level
All of my roms have been direct copy and past. This is the scaling Im using within my rom
<scaling name="MAP 16bit" units="kPa" toexpr="x*0.4072" frexpr="x/0.4072" format="%.1f" min="0" max="450" inc="0.4072" storagetype="uint16" endian="big"/>
I did double check the vacuum lines to the FPR. I have had one come off before and its different than what I am experiencing. I want to mention that when flashed back to non SD and runing on maf I do not have the lean condition occur.
It does in fact say 4bar on top but that also doesnt mean its not defective.

i followed all the instructions contained in this thread with my 4-bar omni sensor and have not had any problems. However, due to all the changes required, even the smallest of typos could lead to a situation like this. I would double and triple check all your rom changes and if you still can't find something, you can always have another set of eyes look over it - like posting them up here.
Out of curiosity, where did you purchase the map sensor from?

Thanks Mrfred, thats actually one of the post where I got my information from.
I went through and double checked everything. I had missed a few tables in developer in my rom that were off from the patch rom I downloaded. Everything seems like it should be now. Thanks guys!
Does anyone have the bolt pattern measurements for this sensor? I have my manifold off and would like to pre-drill it but don't have the sensor yet.
Also, what cars can I cut a pigtail off of that will work with the Omni?

Don't forget the offset:

something like: 0.2340x - b + 0.5, where b = 14.5 at sea level.

Fixed it, after some more searching I found a thread where someone mentioned buying an o-ring assortment kit from autozone, part # 80000. This solved my boost leak. Theres one o-ring in the kit that is a tiny bit bigger than the stock o-ring and fatter, works perfect. Sorry for bumping this old thread.
