I am not a wizard, but I am pretty sure there is more to it than just the addressing - there are all kinds of protocol things going on, prefixes that a module has to send before the others will...

A wizard, somebody who had the tools and know-how to do things like decode the datastream and dump the code out of and modify firmware in non-ECM/TCM modules, sure, one of those guys could probably,...

That's some kind of clanky mechanical noise the sensors are picking up, not something happening inside the cylinder.

One day to go before the post is edited to add the spam links...

You can start your own thread, it's free. Not likely to get a reply from other one-posters from seven and five years ago.

Wrong question... the E38 was used from 2006 all the way thru 2017 - different service numbers (the internal hardware), different applications/platforms, many many different throttle bodies that do...

It's a 6.0 LS, aren't they all the same? You guys must not know much about how these things work.

The 2013 ECM/TCM are expecting the other modules to be at different addresses than where they are in a 2019.

When did this start? Because there is a ton of stuff in the change log going back quite a long while.

I'd check for U codes in every module, if there are two modules the rest of the system can't talk to it's possible it's something like a devID conflict since there's such a spread between the year...

Opening the .xml will append all the graphs to the bottom of whatever you have there now, you may just not be seeing them. It won't replace the ones you already have there.

That's a bunch of random stuff in there too, delete the ones not relevant. There's one for VE with no filters, then two others with different filter strings for different stuff.

I have...

It's still having to add around 20% almost everywhere, now it needs to be tuned. Be real careful with hammering on it until then, since that 20% being added by the trims goes away once it goes into...

There's also something funky in (some of?) the GMPP fan controls, they will run relay fans but not anything variable speed.

Main issue here is, the new ECM still has the 3.6L OS in it, trying to run LS V8 hardware.

A tuning device that happens to include rather limited scantool functions is the wrong tool for the job, if what you're looking for is a scantool.

See, they tell you 'just report the spam, we'll take care of it' and you report it and 3 days later it's still here.

There is a poorly-hidden link in the signature line. This link was included in...

How is anybody else supposed to be any less stumped than you are when we not only can't lay hands on the actual vehicle, but can't even see a log file of it doing the things you say it does?

THIS IS A TEST, ONLY A TEST...

I think they gave you a base file with totally jacked-up Open Loop and Open Loop Gains tables. These trucks with this OS originally had a 10.00 x 0.1 = 1.00 setup;...

The combo itself didn't scare anybody away; lack of info about how it's set up did. Fuel pressure is...? I still don't know that one. Lots of confusion around how you're describing the fuel...

p.s. Good luck with no cats or downstream O2s, but the lightoff spark tables still populated and Cat Test/Post O2 Test still enabled. I'm sure disabling that stuff is just yet another scam THEY want...

You're right, I'm just making shit up. To prove that all you have to do is fill the VVE with random numbers, or all zeroes. It'll still run great. All these high-falutin' VVE tuning methods are just...

And you think that's going to be productive? (it's not)

My very first impression is: completely untouched VVE and 'MAF only', plus a tight LSA cam with lots of overlap? Sure you wanna keep going that direction?

Other very very basic Electrical 101 things to check: What is the voltage at the battery +/- terminals while the starter is cranking the engine? What is the voltage between starter B+ post/ground...
