When I open the 96531706-TephraMod-phenem-sd.bin it says that this file is not recognized and asks me to relate it to another rom. I tried many and it will only bring up vehicle data on the left hand side. No maps. Any ideas what I did wrong? I have ecuflash ver 1.42.

 

sounds like you haven't put the 9653xxxx roms in the correct place, they should go in ecuflash/rommetadata/mitsubishi/evo/ then all should be fine.

 

awesome! Thanks man. I will try this. Hopefully I can get everything set on the computer before I go home in a few months.

 

logging my air temp and noticed it is almost always exactly 195.8 is that normal?

 

Definitely not, at idle it should read right around ambient temp. Make sure you have the IAT scaled correctly and that you're logging the right MUT channel.

 

Thanks for the help I figured it out all I had to do was change the requestedid in evoscan for 09 to 11. Not sure why they didn't have it that way to start.

 

Hi everyone, I'm getting ready to do this conversion and have a pretty basic question regaurding the MAP VE table.
The MAP Kpa side reads:
11
21
31
41
61
101
121
340

So to PSI it translates to
1.5
3
4.5
6
8.8
14.6
17.5
49

So if someone is runing 26psi of boost, why wouldn't we want to rescale that table to include something between 121 - 340 kpa?

It might be a dumb question, but I'm trying to understand this and make some kind of a link between the VE tables and the logs I'm looking at....

 

It is absolute pressure. So, you have to add your atmospheric pressure (14.7psi/101.35kpa at sea level) to your numbers. So, 26psi of boost is 26+14.7=40.7psi absolute.

And to answer your question a bit more...the VE will be varying much more by RPM once you are at your target boost level. So, no need for the granularity at those boost levels. You just need to make sure that you have your max boost covered in your table.

 

Good Write up OP the community appreciates this!

 

Thanks. So lets take Chicago for example. Atmospheric pressure 14.4 (579 above sea level). So 14.4=99.3kpa, my boost is then 0.

11 vacuum
21 vacuum
31 vacuum
41 vacuum
61 vacuum
101/99.3x14.4-14.4= 0.3 psi
121/99.3x14.4-14.4= 3.15 psi
340/99.3x14.4-14.4= 34.9 psi

I know that you don't need to be this exect, just curious if I understand the concept. Bottom line anything under 101 is vacuum, and 121 is 3.15 of boost.

 

Yep, you got it.

 

Also from personal experience when cruising around town you very rarely hit anything below 41 kpa. Below that is just like a blip.

 

Got it. Thanks guys.

I'm still really confused about the MAP VE tables, the more I read the more it confuses me. I will give it a shot and see how it goes.

Dumb question, is there a way to log KPA in evoscan? Current evoscan setting for psi is 0.19347*x-14.4, I'm sure that formula can be changed to read kpa. Would something like this work: 0.19347*x*6.895

Also, will tuning SD be a lot more difficult without being able to log MAT? I have the IAT sensor in my UICP I just can't get a hold of the xml patch from anywhere.

 

Yes, that's correct (to get absolute pressure in kpa, assuming your 14.4 is atmospheric pressure).

 

You can tune SD without IAT
..IAT helps with climate changes.

Once you get started tuning it will get easier.
