like a tool i did 2 things so not sure which fixed it but i disconnected the ecu and also disabled the rear o2. all trims working now
my idle hz are 31 ish so pretty std

 

great, how did you disable the rear o2 priphery ? iam using standard jdm evo 7 rom.

 

there is a table all on its own for rear o2 disable
i disabled it and the CEL enable bit from 0 to 1

 

can you tell the setups because i can't find these values in my rom

 

 

Could be that it is a Evoscan issue.....
Try to read fuel trims with another logger (Mitsulogger) and see if it works.
If you have FAA bit 4 set to 1 the fuel trim must work.
What air flow Hz reads Evoscan?
Also put FAA bit2 and FEA bit15 back to stock (if you have other changes here) and try to read fuel trims after you change those two bits....

Could be something........

 

ahaa thanks lecavturbo but i don't have these parameters in my xml it's jdm evo7 98640014 rom what rom are you using ? thanks daniel i will try that too

 

96532706 v7

 

7 never had rear o2 sensor so it should be switched off anyway what do you have in Ecu periphery faa bit 1

 

Faa bit 1 is set to zero..can i use 96532706 v7 instead of 90550001 ?

 

doesnt work correctly on 7 ecu

 

I am having the same problem right now, my hz at idle are right around 31. Is there a way to make these move?

 

It works, I am running it. Look for a Zaid patched version, I got it off lancer register.
