With the current $$$ cost to tune the E99 ECU that’s in the ZR1, and will be used in the C8, that got me wondering how many potential buyers that might turn off (assuming it doesn’t drop drastically in cost)? What percentage of buyers (total, not just on CF) would even modify their C8?

 

The ZR1 was a low volume production car. There will be TONS of C8s produced, there's even rumors that they already have enough reservations to cover the 2020 model year of production. Since there isn't many C7 ZR1s, and even less of them modified, there wasnt much in it for the tuners. That's why it took so long to tune it and why it's so expensive. That's not the case for the C8. You'll see the ECU cracked much sooner and tuning will be much cheaper because tuners want to get this thing tuned and able to be modded right away.

 

Really want to void a warranty on a brand new ME set-up? Brand new DCT? Brand new electronic system?......No thanks.

 

I think GM will get some tuning in place but it will indeed impact the warranty Otherwise you would not be looking at an affordable corvette.

the phone home nature of the new OS (same ecm) will detect you monkeying around. And you should be careful before you stuff the vette into wreck as the data recorder is not your friend.

 

Won't the C8s over the air updates make this futile? Seems like Chevrolet will overwrite any tuning at any time. Imagine you get the car tuned, as you are driving back home it downloads an update, after you shut down it installs the updates. That would suck.

 

I cant wait to spend $1,200 on a tuning solution, to get to 60 .2 quicker.

 

Agreed. I don’t race the car so what’s the point? Just throwing money down the drain.

 

Might be fun to put a blower on it, like the C7 Z06 and ZR1 came with stock.

 

burning question of the day

 

The L5P diesel ECM had the same problems as the ZR1 and had a similar solution. A customized ECM replacement. There's a lot more of those than there are ZR1s, and they're not a whole lot cheaper. $1700 for the L5P ECM vs $2000 for the LT5.

 

ECU will be less of any issue in comparison to the torque capacity of the base models DCT.

 

sarcasm..funny. feel free to move on. no comment req'd. douche.

 

Muscle Cars & Trucks reported a few days ago on the advanced encryption written into the ECU in the 2020 Chevrolet Corvette. The condensed version is that, according to the outlet's source, "successfully flash-tuning, reprogramming and otherwise altering the engine control unit to increase power output will be next to impossible." During the reveal event for the Cadillac CT4-V and CT5-V, MCT asked GM President Mark Reuss about the Corvette's new Global B electrical architecture, which is shared with the new Cadillacs, and about that ECU.

The context is that the Global B system has been designed to serve the next decade of GM vehicles, capable of supporting advanced driver aids like Super Cruise, full autonomy, far greater and constant connectivity that enables features such as over-the-air updates, the growing importance of cloud computing, and electric vehicles. Reuss' comments have to do with the primary threat to such a system: hacking. Calling the cybersecurity component "very, very robust," Reuss told MCT, "Global B I think is going to be the standard of the industry in terms of the encrypted messaging that travels on our bus between modules. There's a clean side and dirty side to that.

The above was discussed at length in another thread. Bottom line is that the Global B System is a completely different ball game than just hacking the ECU that was in the C7 ZR1. Find and read the thread. Those that think they are going to buy the base car and do a lot of performance mods need to educate themselves concerning this massive change in the C8 and all new GM vehicles going forward. The days of just hacking a Corvette ECU have ended and going forward, performance mods, if even possible at all, will be outrageously expensive.

 

Millions and millions of people have been doing it for decades from every car manufacture so do we really need to tell you "what's the point"?

 

Yawn, they said the same things about the C7. It was going to be unhackable, tuners won't have the capacity to understand the tables, etc. etc. It might take a bit longer than it used to, but the cars will get cracked.

 

I have to laugh, no computer system that is physically accessible has proven to be unhackable. People hack them just for fun. Add the ability to make money from it and it will surely happen. The other possibility is that it may not be necessary. Even the last cpu had the ability to support supercharging and turbocharging. Some mods will be within the range of current programs and data tables.

They are talking about making the communications unhackable so an outside system can’t take control. Obviously it will be possible for an outside system to do that because OnStar proves it.

GM may provide “tunes”. They have already done so, and so has Ford.

 

Once it can be tuned someone will install a big lumpy cam and proudly post the audio/video sacrilege on CF. I won’t be clicking on that thread.

 

It costs about $3000 paid to HP Tuners to get all of the components and credits necessary to tune the ZR1 ECU. That does NOT include actually doing the tune by HP - assumes you are doing the tune yourself. What you yawning, laughing, and lumpy cam gentlemen do not seem to understand is that the C7 ZR1 does not have the C8's Global B system, which will be doing OTA, and as part of that, checking ECU encryption keys prior to performing those OTAs. The HP Tuners mod replaces GM's encryption keys with their own encryption keys. Under the Global B platform, OTAs will only work with the GM encryption keys, therefore, if it runs into your HP provided encryption key instead, the OTA attempt will put you in a SOL situation. Any ECU updates and changes will be supported by "GM approved" tuners or performance mods, if any. GM has already said this

Please resume your naps, laughing spells, and dreams of lumpy cams..

 

It would be a major turn-off for many.
Especially when you see all the disappointment when people are not able to replicate GM's 0-60 time of 2.8 seconds. 495hp and 3600lbs is not going to be that fast compared to other cars, I don't care how fast this DCT transmission shifts.

 

"sacrilege"...?
