What controls the commanded and allowed Low Side Pressure now that the FPCM is deleted?

Global B is available to all now. But its till "buggy" on some models. There have been reports of people sending their ECU's out to be unlocked and then receiving them back, plugging them in, and...

As Greg said, you need to adjust things that control the throttle on cold starts back to stock and start over. Catwarmup has been removed by HPTuners as the EPA came after them over that and a few...

I actually have one

145407

There is a toggle in the TCM along with some torque settings in the TCM and ECU

We all know the YouTube tuners are the best ones

I don't see anymore wording on HPTuners site that says it can only be unlocked and tuned by select tuners. One of their email blasts alerted me to an announcement for the 2024 C8 and beta testing for...

Please sell it as a kit that includes fuel lines as well. I want the easily repeatable option like your DSX Aux kit please :)

You can do it if you create a custom graph with custom math. But I agree it would be helpful if there was a simple toggle to show actual, average, and percentage for Delta values.

Nothing wrong with 2HPSI as long as you are prepared to realign the torque model. It's pretty easy to do but the DSX kit that is coming out avoids this. I've tuned plenty of 2HPSI setups but I want...

Hurry up, I've been waiting. Enough talking and more producing :pray::D

Strangely enough, I've never tuned a 2020 Manual ZL1 lol. I have a 2018, 2019, 2021, 2022 and maybe a 2023 manual file. I just went back a few years to look and NEVER a 2020 Manual ZL1.

I agree

That is pretty extreme. You don't have the mods to require a dyno tune IMO. There are much cheaper ways to go. But you would need the MPVI3 and 4 credits to work with a remote tuner.

I'm assuming...

It costs a lot to tune this platform. Any tuner worth their weight is going to be costly. I would recommend to not bother tuning the car unless you add some modifications. If you want something...

So much info in this thread. Love it.

I have found that the columns sometimes don't split exactly as you would think. Like 3000 | 3200 | 3400 , The column split for 3200 Could mean it starts at 3200 or ends at 3200. Very odd but I...

In this log export you can see it happening. The STFT's go full rich and then the throttle blade keeps opening up, which I assume is because the timing is getting pulled down into the negatives....

I think there is some test routine that gets stuck trying to run over and over when it doesn't see the rear O2's. I'm not sure of the cause but even with stock DFCO settings it was happening. It only...

And I was fortunate enough to speak with you, who pointed me in the right direction with User Defined Parameters(which solved the issue). HPTuners doesn't expose the tables necessary to solve this,...

I can attest to Greg's experience.

I definitely started seeing this on 2022+ Camaro's. The older ones don't do this and none of the C7's do this. You will get the same behavior if you unplug the...

I think this is a bug with HPTuners. I seem to have solved it by doing the following:


-Install the latest HPTuners Beta
-Delete the PID
-Connect VCM Scanner to the vehicle with Key on Engine...

I use the LT4 table and then set WOT to 1.00 on NA LT1's that use LT4 fuel parts. I don't know if that is the "correct" way to do it but I found it easier. There may be a little bit of part throttle...

I don't back SOI up for Ethanol vs Gas as long as I'm not running out of spray window. As for the Lambda changing, if you used the LT4 injector density table, that would be why. Pay attention to...

I was mentioning about why you might keep seeing constant knock. As for the dip, it looks similar to when you have an air turbulence or stall issue due to the intake path, valvetrain geometry,...
