Here is all of the scalings for it. If you need scalings for PSI based boost control with the OMNI 4 Bar, I have those too.

Code:

<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"/>
<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"/>
<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"/>

I think ziad has a better version of the LiveMap app that he is working on, but I haven't had a chance to play around with it yet.

I think that covers all the scaling equations needed for direct boost and Speed density?

Thanks!

I saw you had them posted earlier but I was under the assumption they were for PSI based boost control instead of for SD scaling.

I'm running an Evo 8 Ecu on my '97 Talon using the 2g DSM MAF. To get it to run correctly, I had to rescale the MAF. After some trial and error, my car now runs within about +/-0.5 of the AFR map across most of a run. This also made it so 100 load happens just as I cross into positive pressure at 0psi. It's a night and day difference between when I just had a rough guess at a scaling (2g DSM MAF scaling minus the difference between the DSM and Evo MAF adders.) , and the one that I scaled.
My LTFT are now within +/- 3%.

can i do some pin swaps and run the usdm or edm 96530706 on my jdm evo 7 ecu?
or would i need a usdm ecu to run that rom?

Sweeeeet. This makes going over to the Live-tuning ROM so much easier once it is known to work with this new romID.

If someone can workout how to fix that I would be happy

hey tephra, Im having an issue w/ your big map translator... I DL it, extract files, and when I open it up, theres no worksheet, just the file folders, and .xml doc.
I DL'ed the other big map translator for the VIII's and it just pops up w/ the excell file...
Running vista

DL'ed phenems rom to check it out... Very cool stuff!

Patiently awaiting the IX rom...

I dont know if any said this, but it should be noted in the first post (& second) that immobilizer hex in 9653 needs to be the same as the ROM you changing from. Its looks like its set for cars that had the 9496 ROM, but 9417 and 9642 ROMS have are different.

EDIT: Someone mentioned it.

@gmail.com

Thx Tephra, everything sorted out now, car is running just great.

My problem was related to one of my previous settings for Lean Spool, that was copied over from my old ROM.

Awesome job JOT.....

Small request

Any chance we can also have the scale settings coverted for us, that make use of a Defi boost sensor (as posted over here) and who make use of Bar instead of PSI.

Thx

One last issue I am still having with the big maps relating to Map Tracer and EvoScan V2.7 Beta2......

When doing a maptrace from a log which was done with bigmaps flashed on the car...

I have copied the relevant "bigmap" xml files from the C:\Program Files\OpenECU\EcuFlash - Bigmaps\rommetadata\mitsubishi\evo
folder to the C:\EvoScan v2.7 Beta2\ROMS folder but.....

I still get the following error when I try to open the Hex file with the big maps in.
Anybody been able to get maptracer working with the BigMaps?

Thx

Yay I found the bug in 88590714

hope to have a new version for testers tommorow and then maybe release on the weekend
