I flashed back to the 11 ROM but could not remember the MAFT settings so car would not idle. Went back to 06 ROM but it will only idle decently with an A/R 0f 13.6:1@900rpm. If i disconnect the front o2 sensor it idles @12.0:1 so I suspect the trims are changing but it will not show up in Evoscan or mitsulogger after half a tank of gas. I have ran out of ideas.
Any help is welcome.

 

I thought you said your injectors were scaled via the maft? Flashing isn't going to change that. What you should have done from the start is just zero the maft and use correct scaling in your ROM.

It sounds like your MAFT is the issue.

 

I am sort of coming to that conclusion. With the other rom the trims were fine now on this rom I cant see them. I started messing around with the maft settings after changing to the 06 rom because I could not get the car to idle. When I get back I will probably follow your suggestion.
Thanks for all your help.

 

So there was no fix for stft or ltft not showing up?

 

Yeah there was. I had to turn off the immobilizer periphery "0" bit '5', i.e. set it to
'0'

 

Ah crap, you mean the one that's already 0 here?

 

it is not bit 5 but bit 3 for immo

 

Ah! Cool! Thanks a lot guys! Was there another thread on evoM that you guys got your information from?

Thanks again!

Damn...I still got nothing. I shut off bit 3 first then tried bit 5 then both, but got the same reading of 0.1008. Am I missing something?

My rom is 96530006 and it actually is periphery 0 bit 4 after taking another loook.
Print screen is not working on my pc so I cant show you. Just like you I tried everything I could think of but nothing worked until I disabled bit 4 labeled 'Immobilizer Enabled' hope this helps now.

 

Whats your airflow (Hz) reading at idle, I believe above 40Hz you are not in closed loop anymore so your idle trims would not change. Is your O2 feedback changing?

 

I have mine set to full time open loop. (Runs too lean at idle for some reason ) This is one of the reasons I need to get this working.

I set it back to read closed loop, and set "bit 4" in "periphery 0" to 0 (mine's not labeled) but still nothing. I tried logging ltft in a relatively stock EVO X and it worked fine. I am getting readings from O2 sensor and O2 sensor #2 but no O2 feedback (STFT).

*Question*Doesn't open loop and closed loop have to do with engine load and not airflow hz?

Maybe someone will see something missing here...

 

OK. I found the correct immobilizer bit here: http://evoecu.logic.net/wiki/Periphery_Configuration
Its actually bit 2. Now at least I can read STFT. Thanks guys.

 

Bump for LTFT fix.
