Don’t know if I’d risk tuning my brand new ZR1 (if I get an allocation)...makes me wonder what the situation will be with mid engine as well once released...

I meant the car was too new and we had many posts about the way the LS9 blower was designed that it couldnít be modded. I think it was something about the blower pulley being machined on. Just seeing a little history repeating in the new ZR1. Granted that was mechanical and this is software, I still see the same ďcanít be doneĒ from back then.

Default If they really want too they can, guaranteed! ;)

Precursor to the C8 turbo model!

It may be unhackable today, but as technology increases and the aftermarket does research, someone will figure it out. Question will be, can the aftermarket do and produce a product at a price that not only a consumer will pay, but one where they can make a profit at the same time.

As the computer world has proven to date, nothing is "unhackable" forever.

Should I cancel my order? I see a new one for sale as the owner is unhappy it's not tunable.

thats me... hopefulley someone gets into the ecm soon. I'd pay dearly to be able to tune this damn thing. lots of potential, but useless without a tune.

I envision a stand-alone port injection setup utilizing stock injector port locations and trick-f%$#ing the stock e99 by having resistors (or stock inj) Plugged into the stock harness. Share sensors and get the extra fueling through the aftermarket ECU. The use of e85 and or race fuel would take care of most timing concerns. Torque management will still be a problem for those wanting WOT instantly from a dead stop, thatís only going to happen with a tune.

There's actually two ECUs to crack on this thing. The E99 drives the direct injection system, and there's a separate ECU for the port injection system. It'll probably trip a ton of injector faults when either ECU sees the current consumption doesn't match up with the models due to the lack of fuel pressure behind the injector pintle. Using resistors would be even less likely to work.

What about LMR and all those other big name shop that got their Zr1. What have they said about tuning?

So far, nobody can find a way into it.

There's a research company that specializes in reverse engineering automotive ECUs and cracking their security. They claim to have gotten into the supposedly uncrackable L5P diesel ECU. But this company only provides tools to program the ECUs. They don't write tunes or sell products to end users. So it remains to be seen if their method is practical for retail use, or if they even accomplished their claims to begin with.

I bring them up because they said their next target is the ZR1 ECU. So, we'll see what happens.

That was actually my ZR1 in the LMR video. They are waiting to get one since they cannot yet be tuned. I have heard of several shops doing the same, Weapon X is the only one I've seen with significant ZR1 modding content so far. I spoke with John Hennessey at a Houston car show this month and they were planning to take delivery sometime before the end of June.

Lingenfelter is working on one also so sooner or later it will happen.
If you sell what would you get ?

Every car is tunable, otherwise the manufacturer couldn't get them to run. What the thread title should have been was "ZR1 un-hackable?". There are two ways for the aftermarket to tune a car: Hack. Or purchase access to sections of code representing specific functions. Some cars are basically un-hackable, like BMW which used 128-bit encryption on the DMEs two generations ago. The purchase option costs a lot, so to make it worth while you need large volume or a high product price point. Or, in the case of Hennessey or Lingenfelter they pretty much have to pony up (or hack if it's possible) because they are top-end tuners and can't let a car like the ZR1 pass them by.

Hacking of the newer and newer ECMs is going to take longer and longer and at some point become impossible to market for profitability... or risk having the feds really come for you..

blame it on autonomous vehicle tech.

I invested heavy into BlackBerry for that very reason. Once I found out that they are heavy into network security and then marketing that tech in the auto industry in anticipation of vehicles capable of self driving features becoming the norm as opposed to the exception now..

Are we there yet? Probably not. But the C8? Or C9? Definitely.

for example a Google search of just blackberry explains it better.

Has less to do with emissions and EPA (like the raiding of tuner shops in the past) and more to do with hacking and taking control remotely of a vehicle and wreaking havoc with it.
