    • 2019 Chevrolet C7 Corvette ZR1 LT5 ECU finally cracked by HP Tuners and tuning can begin - $5k to tune?

      HP Tuners is advertising the C7 Corvette ZR1 LT5 ECU as cracked and tuneable. They also offer an unlocking service. Houston House of Power posted what it would cost to tune a ZR1 and looking at the invoice here the price is $5,206.02.


      Why? Well, the spare E99 ZR1 ECM is $2499.99. It seems it makes much more sense to simply unlock your own ECU for $399.99.


      Even if you eliminate the spare engine control module the price is still $2706.03 including labor.

      Houston House of Power states you can save a bit using your own ECM but says the savings are $500 on manual cars and $700 on automatics which is a bit confusing:

      You can save 500 on manual cars, and 700 on automatic equipped cars, respectively by sending in your original modules for unlock service.
      It seems HP Tuners is going to make a killing on ZR1 tunes as far as tuners paying for the privilege to tune them.

        I think its fair. The market is pretty limited (not very many potential customers compared to the high volume lower models or Camaros) and the ECU encryption is very sophisticated so it probably took a lot of time and money to crack it.
        Or they had to pay the rumored 6 figures to a 3rd party who claimed to have cracked it a while ago and they are just trying to get their money back and make a profit.

        This encryption crap on the newer car model ECUs and TCUs is out of control. You pay $120K+ for your Vette, and you cannot mod your own car. $5K for just a tune?

        I agree with you and I'm not sure what they are thinking. Doesn't GM know who buys these? Don't they know their market?

        If a car can't be modded I'm not interested. Things won't change until they lose money.

        They want to beef up encryption to keep people out I think as a test run for autonomous car software.

        They really do know who buy these new unfortunately. You should see the polls on the corvette forum when Ben from WeaponX asked how many ZR1 owners were willing to tune and how much they were willing to pay...
        It was sad, the majority of them said they wouldn't tune even if it was free...they all talked about how the car was perfect as is and scared them enough with stock power blah blah.

        You have to realize the amount of people who actually want to tune is very small and the only reason there are a lot of people modifying Subaru's, BMW's, VW's, Porsches, etc is they sell so $#@!ing many of them!
        The ZR1 is a very small market and the buyers of brand new corvettes are old dudes who wear white New Balance sneakers with tall socks and cargo shorts and a dad bod trying to buy a piece of their youth.
        On average they like waxing their cars and chrome tail light louvers more than modifying their prized possession.

        Even if OEM's made it completely impossible to modify/tune your cars (which really isn't possible) they definitely wouldn't see a drop in new car sales. The vast majority of people who modify their cars are buying them used so the OEM doesn't care.

        When did they turn into Porsche owners?

        There has to be an impact. Look at the crowds at car shows like SEMA which are all about the aftermarket. It's a multi-billion dollar industry.

        Sure, the ZR1 is not a volume car. The Corvette is though and if you couldn't tune it...

        I hate to say it but it makes that Nissan GTR look good! The sky is the limit when you look at the mod potential. It's just too bad that the car is severely over-priced anywhere from $15K to $30K depending on the trim level. I'm curious to see if the ZR1 motor gets put into the Camaro. I think it's just a matter of time, so that the Camaro can hang with the Mustang GT500.
        Out of curiosity (and I'm not trying to hijack this thread), what is the tuning potential of the newer Porsche 911s when compared to the ZR1? I know the new 911 models will be rolling out soon. The spy shots I've seen of the new 911 turbo looks very nice! Oh, that booty!

        If you mean the 992 we don't know and the ECU is locked down like the ZR1.

        The 991 is tuner friendly and you can get a lot out of them from the Carrera all the way to the Turbo.

        Yeah the base Vette owners are fore sure more mod friendly but the modders are still a small minority of total Vette owners.

        I honestly think with the new mid engine Vette their demographic should swing a lot younger because it pisses off the old annoying midlife crisis new balance wearing chromed tail light louver crowd. Those old guys care more about the HERITAGE of the front engine rear drive transaxle vette than the performance.

        The new mid engine vette throws most of that away in favor of a pure performance platform. I really do hope they don't lock the C8 down any more than the ZR1 (now that it is cracked) so people can mod them but we will see.
