Ok so I have made some progress I think, changing the following values to disable EGT and so far so good.

CDATR     0x18196     Configuration byte diagnosis exhaust gas temperature regulation
CDATS     0x18197     Configuration byte diagnosis exhaust gas temperature sensor

CLAATR     0x106b0     Error class exhaust gas temperature regulation
CLAATR2     0x106b1     Error class exhaust gas temperature regulation bank 2

CLAATS     0x106b4     Error class exhaust gas temperature sensor
CLAATS2     0x106b5     Error class exhaust gas temperature sensor bank 2

The 181xx range was the same on my AA box ecu but the 106xx range was a tad different the dummy table starts (I believe) at 1073B on my revision AA box ecu.

If someone posts a link to the AA rom, which is not in my collection, I will find the M addresses noted earlier in the AA rom.  Or at least confirm them.

Is it worth noting these error classes for all the roms?

Have you tried running your scripts against a complete a2l file spen? See what mistakes it makes?

Smiley give me an asap file for an s4!

I've proven the accuracy against the publicly available g and m information.  I'm very certain of the d box translations as I've looked up those in winols.

actually I've just coded up the DTC enable table, the diagnois enable table is more or less static as it's the first function compiled at 0x800000 and 0x80001e

No asaps for the S4. I've got a few for MED9 if you've done any work there.

OK, So i cannot figure out how to remove the EGT's for the life of me! I can't seem to find them even with the locations listed above... how do you do this!?!?! Can anyone do it for me if I post my BIN file?

Thanks

Ok,
I started messing around more with this and here is what I found so far....


Based off of what TWiST posted above, I found the first two locations. I opened my AA box ECU and then loaded an XDF file for an M box. The locations were slightly different than his...

Here is where I found the first 2 EGT values:

CDATR     0x18198     Configuration byte diagnosis exhaust gas temperature regulation
CDATS     0x18199     Configuration byte diagnosis exhaust gas temperature sensor

However I can't find anything else? Where else should I be looking???

Why would you use an XDF for M box when you have an AA box ? The locations are clear and you dont even need winols for this job. If you have something that can handle the checksums then you can do this with any free hex editor. If this is really that confusing for you to do on your own I really suggest that you DO NOT DO IT. Because most likly you will end up doing something wrong and possibly a bricked ecu.

I think it's more of I know what I am looking for but I just can't seem to have it show up... like I said... i found the first two locations that you posted but I can't find the other 4. When I start looking for them I can't seem to find the right locations.

How do you mean you can't find them, the addresses are fully labelled?
