let me get this straight... it doesn't matter what MAP sensor we use in terms of changing anything in the ECU other than setting it for load based or psi based. the only thing is setting up our xml scalings for logging?

changing the map sensor scalings in the original roms was only for emissions...?

I just need to figure out how MrFred figured out the scaling formula's for Psia16,Psia8 and BoostErrorPSI for those 2 sensors so I can make scalings for the other popular map sensors and then I can add them all tot he XML to be easily chosen on the dropdown list. It's be easiest to zip the file and add a folder with instructions on what to change the values to for different map sensors, which I can make for you as well. Gotta go on a taco bell run right now though lol.

Yes, the FUNCTION of the engine isn't affected at all by a map sensor in this rom. We just need the ECU controlled boost section to get input from the map sensor and then we rescale the tables so it reads accurately for ease of adjustment and accuracy. I'm a slow learner but I get it now haha.

let me work on adding this stuff in the XML and I'll email it to you Phenem.
Sounds good

Actually I don't think they need changed. Only the scaling does for the sensor. Those values are specific to the ECU that don't change based on the MAP sensor. So just the MAP scalings only need to be changed.

excellent... glad it was confirmed because this new rom was already giving me a headache lol. will be testing on some 03 and 04 8's soon and will be reporting back. thanks again.

That would be most excellent. What thread are those 2 map sensor scalings from? I know I came across them but I can't remember where lol.

EDIT:

found it. HERE

It looks like those scalings ARE required for the PSI based boost control tables.

Crap! I saw that just now too! Well it looks like we will have to create the scalings for each sensors just label them in some way that we can select the scalings that are needed and we will need to write up a how-to section to implement psi/load based control if you are using anything other than the JDM MAP sensor (because that's the default one I have everything set to)

Look here:

Code:
JDM 3-bar only 
----- (don't add the "-----")
<scaling name="BoostErrorPsi" units="psi" toexpr="(x-128)/(8*5.18)" frexpr="x*8*5.18+128" format="%.1f" min="-3.1" max="3.1" inc="0.1" storagetype="uint16" endian="big"/>
<scaling name="OffsetWGDC" units="WGDC Change" toexpr="(x-128)/2" frexpr="x*2+128" format="%.1f" min="-64" max="63.5" inc="0.5" storagetype="uint8" endian="big"/>
<scaling name="psia8" units="psia" toexpr="x/(5.18*2)" frexpr="x*(2*5.18)" format="%.1f" min="0" max="24.6" inc="0.1" storagetype="uint8" endian="big"/>
<scaling name="psia16" units="psia" toexpr="x/(5.18*2)" frexpr="x*(2*5.18)" format="%.1f" min="0" max="32" inc="0.1" storagetype="uint16" endian="big"/>
-----

OMNI 4-bar only
----- (don't add the "-----")
<scaling name="BoostErrorPsi" units="psi" toexpr="(x-128)/(8*4.23)" frexpr="x*8*4.23+128" format="%.1f" min="-3.8" max="3.8" inc="0.1" storagetype="uint16" endian="big"/>
<scaling name="OffsetWGDC" units="WGDC Change" toexpr="(x-128)/2" frexpr="x*2+128" format="%.1f" min="-64" max="63.5" inc="0.5" storagetype="uint8" endian="big"/>
<scaling name="psia16" units="psia" toexpr="x/(4.23*2)" frexpr="x*(2*4.23)" format="%.1f" min="0" max="32" inc="0.1" storagetype="uint16" endian="big"/>
<scaling name="psia8" units="psia" toexpr="x/(4.23*2)" frexpr="x*(2*4.23)" format="%.1f" min="0" max="30.1" inc="0.1" storagetype="uint8" endian="big"/>
-----
The only difference is the psia16 and psi8 and boosterror which is basically what you posted earlier! That's what I meant earlier is that the Offset shouldn't change based on the MAP sensor. So basically we only need the psi scalings which you posted so we are good to go!

With the Omni sensor there is more than just a constant scaling. The readings are offset .504 psi. 0 pressure (vacuum) is _not_ 0 volts.

Ah well this explains why i'm not getting any boost control error corrections when I flashed this ROM.

According to your profile you have a JDM EVO 9. The 9653 ROM is an EVO 8 ONLY!

I assumed he knew what he was talking about, LOL!

Looks like he has a JDM EVO 9! So NO he cannot!
