Ok guys I need some guidens, I went ahead did a bit of reaserch before doing anychanges in ECU flash and I thought I did this correct but I poped the o2 sencor code once again after about 30 miles.

My ECU's internal ID is: 52680018, inherits: 52680015

So I copy and pasted the following code into my 52680015 file, but like I said after about 30 miles I got the code once again.

What am I doing wrong or what am I missing.

52680015 -> 52680020:

Code:
<table name="DTC P1238 Disable 0x0384 -> 0xFFFF" category="Misc" address="631ae" type="1D" scaling="Hex16"/>
<table name="DTC P1241 Disable 0x03E8 -> 0xFFFF" category="Misc" address="631a4" type="1D" scaling="Hex16"/>
<table name="DTC P1235 Disable 0x0026 -> 0xFFFF" category="Misc" address="549b2" type="1D" scaling="Hex16"/>
<table name="DTC P1233 Disable 0x0028 -> 0xFFFF" category="Misc" address="549ae" type="1D" scaling="Hex16"/>
<table name="DTC P1234 Disable 0x0028 -> 0xFFFF" category="Misc" address="549b0" type="1D" scaling="Hex16"/>
<table name="DTC P0247 Disable 0xF9DF -> 0xF1DF" category="Misc" address="9356a" type="1D" scaling="Hex16"/>
<table name="DTC P0139/P0140 Disable 0x1 -> 0x0" category="Misc" address="503b2" type="1D" scaling="Hex8"/>

 

what code did you get?

 

Since nobody has confirmed this as working. I guess i will go ahead and confirm the following as working on the 2010 Evo X (55570005).

<table name="DTC P1238 Disable 0x0384 -> 0xFFFF" category="Misc" address="633e8" type="1D" scaling="Hex16"/>
<table name="DTC P1241 Disable 0x03E8 -> 0xFFFF" category="Misc" address="633de" type="1D" scaling="Hex16"/>
<table name="DTC P1235 Disable 0x0026 -> 0xFFFF" category="Misc" address="549f8" type="1D" scaling="Hex16"/>
<table name="DTC P1233 Disable 0x0028 -> 0xFFFF" category="Misc" address="549f4" type="1D" scaling="Hex16"/>
<table name="DTC P1234 Disable 0x0028 -> 0xFFFF" category="Misc" address="549f6" type="1D" scaling="Hex16"/>

P0247 is not included, as the definition must be wrong, the value in ecuflash does not match.

 

Yup they work, just did two of them today

Did you flip the bit as well?

- Bryan

 

P0420 Cat below effic...

 

what does "flip the bit" mean? Sorry I'm a newbie

 

"ECU Options Set #2"

Bit.1 ( 1 -> 0 )

- Bryan

 

If by that you mean doing this then yes, or is this not correct?

 

That's not what he means

Look a few lines down on your image. You can even see ECU Options Set #2!

A fix for P0139/0140 will not fix P0420. But, if you fix P0420 (toggle bit.1) you also have to fix P0139/40

 

@ diirk - Thank you for this info!
@ Bryan@GST - Thank you for confirming.

 

Looks like the P0140 fix doesn't work on the 2008 Evo MR. I had a customer come in yesterday for a retune with a test pipe. Did the P0139/0140 0x1 -> 0x0 and also ECU Options Set #2 bit.1 1 -> 0 and the car set a P0140 today.

Bryan - what ROMID?

 

Yeah, doesn't work, just got it this afternoon as well Bryan. Hope there is a fix for this soon. Been reading that it will pop back up after about 50-60 miles after reset. No more P0420 (at least not yet /crossing fingers/).
