Enabling mode23 illustrated

newcomer81 · Jul 26, 2009, 11:11 PM

Enabling mode23 is really quite easy but it took me an hour of reading though quite a few posts for it to click. hopefully this will help others save time. Do this at your own risk

1) Get an open port 2.0 cable
2)Install Evoscan(http://www.limitless.co.nz/) & ECU Flash(http://www.openecu.org/index.php?title=EcuFlash). ECU Flash contains the drivers you will need for the OP2 cable.
3) Head out to your car and hook up your OP2 cable to your laptop. Open up ECU Flash and download your current ROM.

4) Identify your ROM ID

5) go to: Evo X Logging to get the changes you need to make the the xml metadata for Ecu Flash. The ROM ID you just got from above will tell you which 3 lines of XML you will need.

6) Open up your XML metadata definition file located at C:\Program Files\OpenECU\EcuFlash\rommetadata\mitsubishi\evo
the definition file will have the same name as your ROMID
If your ROM looks like the next image then you will need to edit the base file it inherits from. In this example the ROM ID was 52680018. This ROM definition inherits from 52680015.

Copy the XML from step 5 and paste it BEFORE </rom>

7) open up (close it and re-open if is still open) ECU Flash and open the ROM you downloaded in step 3
8) You will now need to edit 3 values. The changes you made the the XML file add 3 entries under the Misc. header in ECU Flash

The 3 changes highlighted above tell you what your changing the values to.
The 1st entry you will change the value from 0x05 to 0x23
The 2nd entry you will change the value from 0x05 to 0x23
The 3rd entry you will change the value from 0x42 to 0x52

9) After making the 3 changes save your ROM and flash it back to your car

10) fire up Evoscan and start logging with mode23 enabled.
Evoscan beta 18 - verified

This thread is just a simple step by step how-to. If you have any technical questions please direct them to Evo X Logging Tephra gets full credit for enabling mode23. Any questions in regards to the steps I listed above I should be able to answer
please let me know if i missed anything

Nice how-to

BTW, there's another way to do it without editing the XML. Instead, in ECU Flash, right click on the Misc tree and 'Add Table'. Just add those same tables described in the XML, then edit the values just like you did.

The original text description was also hard for me to follow at first but this step by step guide should get just about anyone through it with much less support time! Great effort and writeup!

Thanks a ton for this!

updated to show beta 18 screen shot and added additional instructions to edit the base metadata file

does it really make any difference if you put the mode23 xml in the actual rom meta-data file as opposed to the one it inherits from? won't it work correctly regardless?

newcomer81 · Aug 4, 2009, 03:33 PM

Noize had an issue when adding it to a child meta data file but worked when adding it to the parent definition, since he's a mod and it works either way i edited the process =)

So it allows you to log more information? or setup custom logging parameters?

I'm new to this whole evoscan thing and i barely know how to work it :X

newcomer81 · Aug 20, 2009, 01:09 PM

you can pull any value from the ecu to log. the only thing you can't log are data points the ecu doesn't have like wideband a/f. So if you have an evo 10 and you want to data log mode23 is pretty much a requirement to unlock the full potential of evoscan.
