Its original source https://www.evolutionm.net/forums/5353216-post148.html , i modifed mrfred O2 Sim patch.
Also, many thanks l2r99gst for his posts with the analysis of work procedures.

If you want to modify this patch for your other rom then you need to look at these requests in their mut table and substitute them
in the code subroutine decrement the value to 1, then find the address of the symbol the hook (I'm looking for E4 D5 08, 4th byte
may be different then, all as more have mrfred except the last two bytes).

FFFF 6A64 request 13 (front O2)
FFFF 6B36 request 1C (load160)
FFFF 6A68 request 3C (rear O2)*

flash it.

my carman scan lite reed the rear o2 voltage from 0.136 to 0.43 V

Can someone give me a step by step on how to apply this patch to my rom (88840016) because I don't understand any of this?

 

Read carefully the first post, this recompilation code mrfred here at this link https://www.evolutionm.net/forums/5353216-post148.html

 

it's sample for dummys))) all need mod for disable rear o2, but I recall that I experimented with 88840017 and 88840016 in the archive, and may require correction of addresses.

Hello, I have 88840017 evo 9 edm rom. This rom is already tuned by an unknow tuner shop. I save my rom with ecuflash on my pc desktop (hex file). Is possible to apply this patch in this saved rom? I add all the line in the xml present in ecuflash folder, when I open ecuflash and I choose the hex file that I saved I see the new option on the left index. Is correct? Can I proceed with the programming ecu on car? Can you help me?
thanks

 

It's correct this xml definition for 88840017?
