Greeting all
I am new to this site and need some help with connecting my AEM wideband to the 7730 ECM so I can include it in my datalog. But first a little bit about my setup. I have a 3.4L V6 coupled to a 4L60 transmission. I am using TunerPro RT, Ostrich 2, My ECM is a 1227730, $A1 mask and ASHH modified Bin. My laptop does connect up to TunerPro. When looking at the bin file I found the following Scalar comments.


It looks like it may be possible according to the comments but I don't have any idea on what is required to be done. Has anybody done this using the $A1 mask? Do I only need to modify the BIN and connect to Pin F14?
Hope somebody can help. I can forward My BIN, $A1 XDF if required.
thanks
Ray

 

Youll need to patch the code itself. Is there a disassembly file for your mask?

it’s easy to do if youre inclined.

 

Thanks for the reply.
I am not aware of any disassembly file $A1 mask.

 

If there’s no disassembly somebody will have to take the time to reverse engineer it for you write the custom code and patch it, then patch your aldl feed and patch your adx file.
Not too many of us around who can…

heres a base ad read routine to copy and edit and paste somewhere else to do your bidding:
B844 ldaa #0x20 ;SEL CH #2 O2 SENSOR
B846 jsr LF0C9 ;GET A/D READ
B849 staa *L0063 ;STORE VALUE

 

Great. Your link is for a different BIN but I guess that doesn't matter its the Mask $A1 your looking for. My skills in this stuff goes as far as changing values in my BIN and working with the ADX and maybe looking at things in the XDF. Hope that enough to get this done.
appreciate your help.

There’s a lot more to it than that. Youre talking about running custom engine software. This, while easy once you do it, is time consuming and quite technical.

 

OK thanks for taking a look anyway. This is beyond my skills. I was hoping it would be something like selecting a few software switches to make it work. In my original post on the attachment I provided, on the patch C there are parts 1 to 5. Each part has a comment stating to change the scalar value to the value stated in the comment.

Patch C part1

I thought maybe it would be something like changing these values but not sure what that would accomplish.
