Truth - doubly true for Holiday weekend.
I would recommend double checking all your connectors are firmly in place, and disconnect / reconnect the battery, and see if that helps.

OP said LT4 without specifying vehicle type, so I only included the LT4 based vehicles that are known to have WBO2s. :p
You don't, unless your vehicle has WBO2s. Unless it's a CT5 Blackwing or Escalade-V, it doesn't have WBO2s.
This is certainly the case on the newer direct injected engine. E.g. the LFX V6 engine was offered in several models in both "flex fuel" and non "flex fuel" trim. The way you know is whether it has...
Right, so the hpt guys should give away their product maps and help you cheat the EPA to make your life easier. :confused:
Correction, you have an L82 or an L84 - there is no L83 in 2021.
If you remove all of the DFM hardware (if it's an L84), the E92 (older ECM) should be fine. You will need to recalibrate the high...
2023 5.3L is Global B, I don't think any of those applications are supported
I'd heard recently that suspension fault codes / modes can limit vehicle speed to around 85 MPH. do you have any suspension related trouble codes ?
Every factory calibration is a little different, some show more KR than others. How the calibration deals with that is equally different from one platform to the next.
The ECU always starts at...
Those would be global B, I don't think they are supported...
I don't think 2023 Sierra is supported...
I had troubles with loading apps on a new laptop, I had to disable S mode.

Yeah, we used an old school cam degree wheel and a dial indicator on a spare engine we had to sort it out... Even that's not 100% accurate, but it gave us enough information to sort out what they...
Good luck, not sure how zzp did it, but there's a bunch of tables and parameters that don't exist in the editor to calibrate these cams correctly. The valve event timing appears to be the same as...
Thanks for the reference! I just a picked a cylinder head randomly.

These are HEMI heads, but all it says is...
Which stroker kit, bigger cam, or modified cylinder heads in the GM world has ever received a CARB EO? I know some of the superchargers have but none of those touch catalyst warm up tables.
I'm...
DPS won't even do what you're trying to do here, anyway. You need someone that knows how to unlock the module so the VIN can be changed, etc. DPS essentially does the same thing SPS does.
Out of curiosity, under which circumstances do you think these parameters would need to be changed in order to pass CARB's emission tests where the vehicle was otherwise failing?
E92A, no it doesn't
Yes, thanks, that was the point I was trying to get across, but apparently "it's not true". ;)
Trafficking in what is certainly stolen software (GM DPS on hacker sites) is what got you banned. In any event, unless you have the knowledge that someone like WAMS does, you won't be using any...
Most (if not all) aftermarket companies use OE cam cores as a starting point, and there's little difference between the LFX and later model LLTs, the main difference being the LLTs had the...
This probably isn't the place for the debate, but the fact they are "EPA compliant" is pretty much a marketing term. For the EPA to consider anything to be acceptable as far as modifications go, the...
The bricked ECU part sucks, to be sure, but unfortunately with the way things are in the US these days, nobody should expect any aftermarket companies to offer software support for stuff like this. ...
So, you're mad because you can't use the product to disable OBD-II diagnostics to allow the running of illegal emissions defeat devices?
