^looks yellow on my monitor.

I'm guessing that they are using a stand-alone ecu... they're perfectly capable of providing a stand-alone, so why not...

A standalone is not going to play nice with like anything else in the car.

It makes sense that a manufacturer would want to control the software and how the hardware responds, especially with over-the-air updates available. Need to keep their system on lockdown. License it out to a few with restrictions.

Nah. Protecting their IP since thee car is connected to their servers. Much more than toying around with afr ratios to get the most out of mods.

Now, if GM was smart, they would have made two separate systems (engine control & everything else) because someone is going to crack the car in the hunt for power and it is going to be a big problem for GM with access and operations of their vehicles.

Also, to whomever cracks it. Expect to see lawsuits.

IDK how the whole John Deere thing turned out, but I feel like that was the start of all this bull**** surrounding "you don't actually own your product and you can't modify it any more because MUH SOFTWARE IP!!!" seeping it's ugly head into the automotive industry.

That's one of the worst parts about considering a car upgrade now-a-days.

This isn't the first time this has happened. I'm pretty sure the Challenger had an encrypted ECU and they couldn't be tuned. I'm not sure if that was ever overcome and I don't care enough to research it.

Default ProCharger Announces Supercharger Kit For C8 Bolt On Pump Gas




Quote:
Tuning options for the C8 Corvette are, for the moment, quite limited. While some brave owners and tuning shops have experimented with installing turbochargers on the car, the vehicle’s encrypted ECU limits the payoff that pricey upgrades like these can have and can also make tuning the car a risky endeavour.(they spelled that wrong That's for UK. In US it's endeavor, ironic coming from me)

Now Kansas City-based company ProCharger claims to have developed a solution to the problem. The company’s new centrifugal supercharger system for the C8 Corvette is allegedly capable of boosting the output of the factory GM 6.2L LT2 V8 engine from 495 horsepower to over 700 horsepower. The details on this new C8 Corvette compatible supercharger system are slim for the moment, but the company says that it will be a bolt-on intercooled system that can run on pump gas.

ProCharger also released a video this week of one of its supercharged C8 Corvette development cars revving and doing a burnout, which was accompanied by the tagline: “What does a 700 horsepower LT2 sound like?”

“Thanks to the amazing engineers at ProCharger, the world’s first bolt on supercharger system for the Corvette C8 platform, is just around the corner,” the company said on its website.

While tuners have yet to unlock GM’s encrypted ECU for the C8 Corvette, it’s good to see the aftermarket figuring out new ways for owners to boost the performance of the new mid-engine sports car. After all, tuning and modifying has always been a big part of the Corvette culture, and there’s no reason for that to go away with the C8 Corvette.

We’re still waiting on ProCharger to release details on pricing and availability for its new supercharger system, so for now, check out the video embedded below to see and hear the company’s C8 Corvette development car in action.

Default Another C8 Corvette Has Fallen Off A Shop Lift

Quote:
Another C8 Corvette Has Fallen Off A Shop Lift

A Chevrolet C8 Corvette Stingray has been wrecked after falling off a two-post car lift somewhere in North America.

As the C8-generation Corvette is mid-engined, its weight distribution is very different than the C7. In fact, whereas the C7 had a 50-50 weight distribution, the C8 model has a 40-60 split. This means the new car needs to be lifted differently than its predecessor. Evidently, the mechanic at this shop might have not received the memo.

Two images recently shared to the Corvette Forum show the Rapid Blue Corvette resting on its rear after slipping off the two-post jack. In all likelihood, the mechanic didn’t use the correct lifting points at the rear of the vehicle which, as Corvette Blogger points out, are placed much further back than on the C7.

The force of the fall has caused a significant split in the bodywork of the sports car and while not visible in these photos, there’s a very good chance that the frame has also been bent. If that’s the case, the car will immediately be declared a write-off and will probably go to a scrapyard where it may be sold.

This isn’t the first time a C8 Corvette has slipped off a two-post car lift. In June 2020, a very similar incident occurred when a Chevrolet dealership in Jacksonville, Florida incorrectly lifted a red C8 Stingray. The Corvette in that incident is also believed to have suffered irreparable damage from the fall.

I think GM says 40/60 weight. But it can be even more if your wrenching, or there's crap in the vehicle. Poor owner..it will never really be the same. If fell slowly down onto one strong point and removable front clip was damaged then it might not be to bad.

This shouldn't matter if the shop uses the designed lifting points. These design points "should" account for weight distribution. It's no different than fwd cars where front weight could be 70% up front.

The mechanic is clearly liable, but manufacturers don't do anyone any favors by the way they do not provide clear and easy to identify lifting points. It should be easy to stick a mirror under a car to figure out immediately where it needs to be lifted from.

Mechanic should have checked the manual, am I the only one that ever checks the manual? It shows where jack points are, and with most cars, if you look at them, they are clearly identifiable (once you know what you are looking for, a seam, a bump-out, a flat spot - there is typically a telling feature).

New/unfamiliar car model, tech/mech didn't take the time to confirm jack points, car go boom.

And that tech could have been crushed under that C8.
One more reason (the most important reason !) to take some time and do things properly.
Going to work is nice but coming back from work unscathed is even better .

At a minimum, Google will but it's in the manual. Google "V8 corvette lift point" will show a red C8 that fell off the lift in the same manner. Hard learning lesson for these shops.

O yeah..I'm anal, my Avanti s I open door hood trunk then close them just enough to catch the locks, then bring her up slowly USING THE CORRECT LIFT POINTS..I worry about my fiber glass cracking. I don't care that's what I do, maybe you don't have too but i do..

European C8 Corvette will lose close to 30 HP!

https://www.midenginecorvetteforum.c...close-to-30-hp


European C8 Corvette will lose close to 30 HP!
Today, 01:35 AM
Just got the information and confirmed that with multiple dealers that the European Corvette will have reduce in overall power thank to the requirement to install a Gasoline Particulate Filter to meet EU emission laws. The power changes as follows:

Horsepower: 468 HP (down from 495)
Torque: 455 Lb-ft (down from 470)
0-60 mph: 3.5s (down from 3.0)

To me this is a huge let down since the european C8 prices are pretty high compared to the US market (even though 2LT Z51 is standard here).

Default Somebody Has Finally Unlocked The C8 Corvette's ECU

Somebody Has Finally Unlocked The C8 Corvette's ECU

Quote:

This has taken an age to get right.

When the C8 Chevrolet Corvette was launched in April 2019, we were all impressed by its baseline performance, but as any aftermarket tuning enthusiast will tell you, there's a lot more potential to be extracted from any car that leaves a manufacturer's production line. However, just as was the case when the Nissan GT-R arrived on the scene, the electronic control unit (ECU) was locked from the factory to prevent this sort of post-production enhancement. Either you live with what performance you have or you run the risk of bricking the ECU and having nothing more than an expensive garden decoration.

In the case of the Corvette, the ECU is so well safeguarded that even Hennessey said back in 2020 that it might need GM's help to unlock it. In July of last year, GM said it would not be providing that sort of assistance to anyone, but now a company called Trifecta Performance has finally mastered the ECU on its own.

"This has been a long time coming," says Vince Geglia II, owner of Trifecta Performance Incorporated. "Today's success has its roots in a project that started the better half of a decade ago. We absolutely respect what GM has built here [...] GM without question put [its] best foot forward with the C8, and from a tuner's perspective, this car deserves nothing less than the humblest approach." He goes on to say that, right from the first time driving the car, it became very clear that it would be difficult to improve on such a great car. In fact, he didn't even believe that his company could extract any more power from the car, and that turned out to be accurate.

Despite adjusting the air/fuel ratio, the ignition timing, the direct injection timing, fuel rail pressure, and variable cam phasing angles, Trifecta found that, although its changes were apparent, "none of them led to measurably significant power gain." So what was the point?

Fortunately, all of this effort was not for nothing, as Geglia explains: "While we didn't find power, what we did find is that the C8's software largely works the same way as the older ECUs, [...] and that we were able to modify the parameters required to make power adders work on the C8 without standalone or piggyback systems."

As you may know, there are many aftermarket performance upgrades available for the C8, but they all require an additional ECU to function. Trifecta's solution allows you to stick with the factory engine management systems, which should prevent the common issues (overheating, failure to select a gear, et cetera) that the transmission suffers when the ECU is fooled into thinking that the car is not making more power than factory.

This new solution will allow owners of the C8 to save on aftermarket management systems and replacement clutches, but it'll likely still be some time before we see a supercharged or turbocharged C8 running on just its OEM ECU. For now, Trifecta will focus on refining the way the car drives, and in time, we're sure the floodgates of modifications will open from other tuners, just as they did with the GT-R.
