I searched around on this forum a lot, but I haven't found a concrete answer to this. So, I'm working on a huracan tune using DS1 and the provided TunerPro XDF. I see the DTC Codes and DTC Masks tables. I see that Masks says to set to FFFF to disable. So, I'm assuming that the one table gives you the ID of the code be decoding the hex somehow. The description of that table is the following:

[DTC] DTC codes (high 2 bits = PCBU prefix)

So, do I just need to figure out which cell the code(s) i wish to disable are and then mark FFFF in the other table in the corresponding cell? And how do I go about decoding them? The most obvious codes I would be looking for are P0420 and P0430 for catless/offroad application. Any advice/guidance here would be appreciated. Neither table has axis labels at all. They're both 45 rows by 32 columns. So, I'm guessing they just mirror each other and you use the masks table as switches to turn the codes on or off (and different MIL settings like first error, second error, etc). I just can't figure out how to read the codes table to know which ones I need to switch. Please help!

Doesn't DS1 come along with a "how to" or a user guide? I can't believe they're giving you all that info but nothing more?

They do have both a 'user guide' (which provides information on actually setting up the unit and flashing calibrations) and a 'starting guide', which provides a lot of basic tuning information (mostly focused on DAZA, less on V10). However, they explicitly mention that changing downpipes (in the DAZA context) will produce fault codes, and they cannot engage in a discussion related to bypassing emissions systems. That said, not all DTCs are emissions-related, so I don't know why they shy away from that discussion completely.

The code from one table is in the same position as the mask in the other. P codes have the top 2 bits clear and so for example P0123 will appear as 0123. If you can't find something in the table because TunerPro doesn't search a hex table, you can copy and paste it into a text editor and it will soon find it for you. Re 0430, it could be absent on a dual ECU setup, but it isn't something I tested since we stopped deleting emissions codes before this product launched.

This is helpful! So it's the 2 highest bits for the component group and then the remaining 14 bits are the code number? Does it work the typical way where 00 corresponds to 'P' for Powertrain, 01 to 'C' for Chassis, 10 to 'B' for Body, and 11 to 'U' for Network-related issues? Just trying to understand how to interpret this so if I see a Chassis or Body code, I'd know how to find it. I don't anticipate needing to disable any of those, but I just wanted to make sure I understood the table.

The approach I was going to take was to copy both tables into excel sheets, so that I could edit the corresponding cell in the Masks file if I need to disable a code. Then, I can just copy the table body back in.

Yes

the best advice would be: search for CDKATSP, FHOKH and cut it out proper way

as for the dtc table, ive got this for 17.1.25 idk if it helps

upload the original file

Perfect. Thanks again!

Neither of those parameters exist in my XDF. What is the proper way? Someone just explained to me how the DTC tables work, which is exactly what I needed to know.

This is for 17.1.1 (car is a Huracan). I'm not sure how different it is from 17.1.25.

I don't need someone to modify it for me. I was trying to understand how the tables actually work so that I can do it myself while tuning it. The bin is totally stock currently. I'm setting up a base map, and I wanted to know how to turn off irrelevant DTCs on my setup. I appreciate it tho!

I was not going to modify anything for you, I was going to give you a fully defined map pack with all the locations for your dtc tables. I dont do calibrations for free.

Oh that would be great. I attached the stock .bin file.

Just bumping this. Did you see the .bin I uploaded?
