Update, disabling the C1507 worked :)

Looks like there some of P codes are tied to the C codes, hope this helps someone else out.

I wasn't able to locate a C1507 code, but I did find a U1507 code with this description "SCP (J1850) Invalid or Missing Data for Vehicle Configuration". I've disabled that code and will report back...

So why am I getting a code from a module that's not connected?

so you’re saying I can never turn it off because it comes from C chassis module? Which I don’t have connected at all?

Here's my bin https://drive.google.com/file/d/1Aro5QagUq1hUHDAUYM2_cpjllY8f5JEt/view?usp=sharing

I don't have an xdf because I just change things with universal patcher.

While looking around I...

Thanks for pointing me somewhere :). The funny thing with this code is that I don't see it in the DCT list when trying to disable it? I'm using Universal Patcher to edit the ECU... any idea what...

I'm sure it's a C not a P :(

Hi All,

I'm getting a check engine light on my 2006 LQ4 after swapping it in an older jeep. The error code is C1507 and the description is "Unknown", I've done a bunch of google searches and...

Thanks dave,

I'm hoping to do this without a vss, so I'll keep poking around to figure out what settings need to be changed in the ECU.

Use PCM hammer and look at VTD settings that needs to be updated

Can you screen cap some of DFCO settings? I'm starting with a BIN from a manual 6.0L truck, the issue I'm having is the engine is stalling when decelerating.

The route cause I believe is that I...

Thanks for sharing this, can you confirm it's been test on 811 OS? in the readme file it says its for the 603 OS ?


Also, do you know what the configuration is for DBW or Cable and Manual vs...

I have a 2006 and just want to do a stock tune with the basic deletes, is the best path forward to just have someone who knows do it with HP tuners?

Or should I muck around with trying to figure...

Looks like it's called VTD in this version of the OS / XDF . I'm going to try changing the parameters and writing the PCM.

This download doesn't seem to be working for me, what should I set the value for VTD_Configuration to? it's listed as unitless and has a current value of 1.

I also see VTD_Fail_Enabled_Bypass...

I can't upload files, so here's a shared file link https://drive.google.com/file/d/1zq171_wmK54-2YZyiormK_oD809jwN3G/view?usp=sharing

Maybe someone can download it and upload it back?

What I...

really old thread... but thought I would post that I have a 2006 Chevy 2500 HD with a 6.0 and NV4500 manual trans. The OS is 12587811 and I have the xdf for it if needed.

I have a PCM with the same OS and used https://universalpatcher.net/ to export the xdf. Haven't written back to PCM yet, but the xdf seems to work.

I have the same OS and used universal patcher to generate the xdf, haven't tested writing with the xdf yet but it seems to work. DM and I can send you the xdf
