I'll believe it when someone is selling it, OR when we see a deleted truck do a power run. It would be nice if it is true...

It does seem odd he said 30-60 days 3 months ago, all we get is a video of a read and flash, and now the video won't play(or he got tired of being attacked in the comments).

Default L5P Tuning

Every time someone cracked into a new ecm and actually did it, they showed it in the truck and the power differences on a dyno. At this point, if what he says is true, put a damn tune in it and show the new power output. If all he can do is flash but canít tune it or anything else, heís accomplished nothing. No one wants to flash a stock tune or blank file or what ever junk he has going back and forth in the ecm, the point is to change the factory parameters.

The flaming is warranted imho. Donít come out saying your the first to do something with half the product not finished

Is this SR research? If so they arenít tuners, they donít know what to change. Maybe the ecm isnít capable of being flashed in the truck. They changed the tune and flashed it in. Did it work? Why would someone go through that much trouble to make a video.

I do know it is being worked on. There will be tuning available, but the time frame is not known.

Whether they purely only build the tool to flash or not, itís half finished. The only way anyone will know it worked is by changing a bit or hex in the program, flashing it and then scanning the ecm for said changed bit or hex, otherwise, how did you know anything you did made a change? They show none of this. You donít have to be a tuner to do that and they certainly can figure that out easy enough If they hacked into it.

Iíll never say it canít be done but showing a video like that proves nothing and leaves the door open for exactly what happen

I thought he did change a part of it, it looked like. But I donít know much about hex or programming. And who knows if it did actually change something.

Am I the only one that is kinda hoping tuning doesn’t happen on these trucks. That a way there not as popular and the price will be right when I’m ready to buy one.

Wasn't that an LML tuning table he was working on?

^^ that was kind of my thought too. How easy it would be to spoof this. Just flash another truck that is not an L5P and have the program say it is

I think it will be tunable, but the final $$$$ cost and final flash process may turn a lot of people against even bothering with it............mostly IMHO due to the cost of tuning it.

There are reported issues with these ECM's failing and Injectors failing on the L5P, the Turbo is completely different in the way its being controlled, and all the other modules have to all be happy and play nice with it.

I can imagine GM employing all kinds of cross checks that may limit the ability to really get these to tune the way older models do...........by allowing other modules to limit the power, and we still need TCM Tuning as well, that will be the next step.

I can see a modest power increase with deletes being the norm, and higher HP builds being less common, the LML's can make decent power, but will never make anywhere near the power an LB7 does.

The LML code is too complicated and convoluted to really make decent gains, IMHO.........even 7 years later they still are a disappointment compared to the previous models.

The fastest and most powerful Dmax trucks are all older LB7's with a few LLY and LBZ models or powered by stand alone ecu's.


I am sure we will see some kind of tune available in the next 6 months or so...........and then we can see how quickly GM reacts to it, if they even care.........LOL

I’m happy to finally see some progress forward
As far as ease of tuning and $$$ all we need is time and patience...
Playing my n64 yesterday compared to my PlayStation 4 I got a sense of how far we have come in 20 years!
