As this engine is obviously not based on the LT1 that this section of LS1tech is about, expect the thread to be closed and a new "GenV" forum to be started.
I too am miffed as to why GM would again re-use an engine designation that's been used.
LS3, LS4, LS6, LS7, now LT1 that's already been used twice before.

Besides the "LT" name has alot of history and meaning for GM with Big technological advancements. This rendition of the LT1 is no different, despite the fact that It is a Completely different "small block"

So wait, the new motor doesnt have an optispark?
JK
In all seriousness I really hope GM doesnt lock the car down as much as some people are saying. The consumer will always win, why would I buy a sixth gen camaro if I cant do anything to it? Have they forgotten their core customer?
Not to mention, how much is this unneeded bullshit Big Brother technology going to cost the consumer?

This new engine sure has a lot more in common with the LS series than it's namesake.
Why re-hash the LT1 monicker ?
As for the tuning side of this.....
GM has been looking into the tuning of their platforms for some time.
The newer vehicles already look for tuning & PCM EEPROM flash counts to the PCM via the network.
It's only common sense their next step is to make engine control modifications difficult.
The nature of a GDI engine & the complicated fuel delivery/ injection modes coupled with variable valve timing all to maintain power, drivability & the bigger picture emissions.
Couple that with a larger displacement & higher power output all those things come to risk. Wind that rubber band tighter it becomes easier to break you could say.
But there are far more to consider in engine management strategies once GDI & VVT are brought into the mix.
Just fuel delivery alone is not controlled via pulse width.
It's the fuel pressure itself that's increased to the injector to deliver more fuel.
Have to deliver fuel quickly in a specific time frame & this is the best option. Thats why the need for a high pressure pump, to force the fuel into the cylinder directly & volume control.
GM has to warranty the catalysts for 8/80 still & that's still a biggie.
Now with GDI that part has become a bit more expensive.
They require a special catalyst to live under the conditions this engine can run under & produce.
They would do these things to PCM's IMO save warranty costs & emissions requirements.
Their not really concerned about the true gearhead who is gonna rip the cats off & mod the heck out of it.
Their looking @ the cars they're selling & have to warranty.
Heck I'm happy where still getting 450+ hp cars coming with this new 36.5 CAFE standard coming.
Trust me I think the future for automotive looks dim in some aspects.

Perhaps its because any other code name would sound silly. I certainly wouldnt want a QT-1

I can assure you GM can and will void the warranty of the entire power train if the ECM is tampered with, additionally GM will void any extended warranty purchased as well. GM is data centers all over the globe are centralized and linked. Going to alternate dealerships will NOT work. Once the ECM is plug into the encrypted data is fetched by the servers.
If the servers detector tampering within the ECM the server will send a void notice to the dealership where the impaired vehicle is being diagnose. Ask any REGIONAL SERVICE REPRESENTATIVE working for GM.
GM is unquestionably subject matter experts on their vehicle. A Lawyer or Lawyers will be hard pressed to prove their case against recorded data on the ECM/vehicle in question and expert engine management engineers.
The judge will understand that the owner illegally violated state and Federal EPA/Smog Laws. Which states the ENGINE CONTROL UNIT cannot be modified by anyone but GM as tested by the EPA. The problem only compounds from possible jail time and $20,000 + fines.
I do not disagree that GM will at least try to void warranty work, but if the consumer is conscious enough and has money, there will be a court date.

I can assure you the ECM will not be tunable.
I have several GM products.
And if you really think some 14 year old stand alone kid is hacking the D.O.D then I have a VCR I want to sell you.
No one has been had or trolled here. As I've stated something very very power is on the horizon for a GM vehicle. The heads are the real potential there is significant reasoning in reversing the intake and exhaust valves. And going to a 12.5 degree valve angle with raised ports.

Keep faith in GM.

as was said before, diesel owners had the same line of bull fed to them... then they made those same people look dumber than a box of rocks.
btw, sales will suffer if its untunable. about the only way to make up for that is the ecm is a completely self tuning entity. you seem to be one cocky computer geek... usually those are the ones that get crushed when throwing
out that sort of challenge.
oh, and one last thing... the only faith we really truly have in GM is for them to pull defeat from the jaws of victory.

It is direct injection. You can increase direct injection as high as 16:1 compression because the fuel cools the cylinder as it is shot directly in. Mazda has a 4cyl running 15:1 already. The possibilities are good. I welcome the new LT1 but let's face it, there has to be a new section for it.

Hot Rod will have a sheetmetal manifold, belt drive distributor, and a carb on it the first month. DI replaced with Meth Nozzles
Really though, there are aftermarket ecu's that control DI and cam phasing if a guy is in a super hurry.
Can't wait to see what the new canted valve heads flow or what they can be made to flow.

Interesting thread. I did some patent searching to see if GM applied for anything on this ecm approach. Found this that speaks to some of the points made in this thread.

From the above link:
"A vehicle state manager process is used to first determine if the vehicle conditions are suitable for reprogramming of a particular ECU and, if so, the vehicle state manager then maintains the proper vehicle configuration during the reprogramming operation. The system and method can be used to automatically reprogram a vehicle ECU using new programming received by digital satellite broadcast or other wireless transmission to the vehicle."
So, essentially it can be "reprogrammed". And this seems to be worded that it won't automatically result in no-starts or a return to stock tune from big brother, but it "can"

Generalation V LT1 info
Hey mods,
shouldn't this thread be moved to a new heading?
We need a section devoted to GM's new engine.
Trump
Heading: "Generation V LT1 Engine"
sorry was watching NFL football.

Funny, I was thinking that earlier.
If these heads are that good, what would stop the aftermarket from producing intake manifolds that will use "normal" in-manifold port style injectors and a LS1 or something style PCM?
Of course, this would facilitate transplants of this engine into cars that didn't come with the genV LT1 engine like our "old" 98~02 F-Bodies.
Will this head bolt up to an LS1/2/3/6/7 style block?
