Recently gambled and bought the Thorton device
They sell 3 different ones I believe 15-30-60 HP levels I bought the 60
Also they claim 5 MPH gains on the 60 and increased throttle action
It takes about 150 miles of driving for it to completely "learn out"
However after only 80 miles of normal driving this is what I've noticed
1. My average MPG was 15----- After re setting it ---It is Now 17.5 !!!!!
2. The idle note and sound is far more crispier sounding -- When flooring the throttle in P/N it does not sound like any GM V8 I've ever heard ! Sounds more like a Lambo or Ferrari
3. After speaking to the owner he says the max HP takes a full 150 miles BUT I can already feel that it has somewhat more HP/TQ
4. As a pro tuner of 20 years I doubt that a tuning plug and play device can add 60 HP-- However I'll follow up after about 200 miles and report back
Even if it only gains about 20-25 HP Still that is an amazing thing as tuning a C8 with HP Tuners costs about $2500
They offer FULL REFUNDS if not satisfied But so far I am and expecting even more results and am 100% happy
Best thing ??? $100 cost !!!!!!!!!!!!! Not gonna break the bank-------LOL

 

I guess this product is similar to the Diablosport Chip back in the days. Just hope it works.

 

I’m a bit surprised with your post. You didn’t mention you had 12 shots of vodka so I guess I’ll be waiting on your thoughts after more miles 😉

 

You sure you didn't buy that from a JC Whitney catalog?

 

Without a before and after dyno pull, any assumptions or "seat of the pants feelings" are just speculations. But hey, it's your car, your perceptions, have at it.....

 

15, 30, or 60 HP gains? Is it like NOS?

 

Someone got his password OR he knows something that we don’t

 

FU how dare you spew out insults to me when all I am doing is reporting results
As far as you go Next time cut the Xanax's in 1/2 !!!!!!!!!!

 

See post #7

 

A miracle device that makes a small block Chevy sound like a Ferrari? Sign me up...

 

I thought everything on the CAN was encrypted, is that not the case?

 

They are a scam:

Look you non sayers I have been tuning LS and LT engines only !!!!!! for over 20 years And of course I was skeptical about their claims-- Over 5000 tunes on gas engines and over 1000 D Max diesels
Who is a scammer ???? HP Tuners !!!!!! wanting over $2500 for an ECM replacement and even then on dyno reports I've witnessed locally HP at best showed minimal gains of 10 in HP/TQ for $2500
So go spend your $2500 on bogus HP Tuners crap ----- EFILIVE will not touch a 2020 + ECM as they are encrypted and the tuning advantages that HP offers they say are SCAMS
Thorton is for $100 price offer far superior throttle response and a crispier idle note
I have nothing to gain by these reports as I do not sell them
However Even if Thorton is off on their HP gains its not that all BS
The Throttle response can be purchased with Solar or the Pedal Commander--where the cost is above $350 So for $100 it is a far better investment and Thorton offers a 100% satisfaction warranty refund
As a Pro tuner of over 5000 GM vehicles----and an owner of 9 NEW corvettes in my recent years
I'm just telling you that this device is worth the $100 cost just for the throttle response--the idle sound/note--the fuel milage increase and future HP /TQ gains
As mentioned I would report back after the 150 mile learn out about the HP and performance gains

My C8 is a base model NON Z51 advertised at only 3.0 at 0-60
with our crap 91 oct fuel in Calif making it even lamer at 3.2
I am pleased to report that recently i recorded 4 0-60 times of 2.6 !!!!!!!!! after the Thorton learn out
Also using a separate device I knocked off 6 tenths from 0-100
Now that ive reached the 150 miles-----
If you don't like what I'm reporting that is simply your uneducated NON Tuner opinion
and you are certainly afforded your opinion
But in an argument with me as a NON TUNER and un willing to accept REAL results simply to me makes you ignorant--------
You may be rich and can afford a new C8 but your arrogance proves to me your 4th grade education again FU

 

I get that you see yourself just sharing your perceptions of this device, but since you have thousands of posts on this forum, and claim a ton of LS/LT tuning experience, wouldn't you expect skepticism from this community? Yea, I have no tuning experience, am just an old shade tree mechanic, but I have the common sense and experience to know that no $100 device give me 60hp by plugging it into my OBDII port and driving around for 150 miles. Short of a cheap shot of nitro, it's not happening......my initial post on this thread simply asked for a pre- and post- dyno pull. You don't owe me or anyone else ****, but if you want someone to take your claim at face value........

 

I’m modding my Z06 at the end of the year. Dragy is going to be my dyno. I’ll pick up a Thornton, do some pulls for fun and return it.

 

I'm more interested in the 5 MPG gain! Maybe it just turns off four of the fuel injectors when you're cruising or changes the MPG on the gauge cluster to read higher.

 

How in the world this particular device bypasses the locked ECU and manage noticeable performance?

I would like to see some 1/4 mile track strip times if possible. I just the OP is on to something negative or positive which appears.

 

GM's new E99 ECM in the 2020 C8 Corvettes involves multi-factor authentication involving dealer employees & credentials and a Diffie-Hellman 2048-bit key exchange using a SHA-256 hash digest that is unique for each VIN PCM & TCM.

The Diffie-Hellman 2048/SHA-256 ECM/TCM is not a STATIC security implementation, it is currently un-crackable by even the best in the aftermarket tuning world.
Current estimates to crack Diffie-Hellman 1024 is 35,000,000 core years.
It would take 35 million CPU cores 1 year to crack a single key exchange, and the key exchange is unique for each VIN. Diffie-Hellman 2048
Forget about it, not going to happen.

Now then, a stand-alone aftermarket PCM that could partially by pass the rolling code encryptions momentarily will cut off factory instrument cluster, HVAC, audio, BCM, power windows and eventually will obtain authentication error which will alert On-Star Remote to shutdown the car.
None of it will work because it has security dependencies on the factory ECM. Every module that communicates with the PCM/TCM uses 2048-bit Diffie-Hellman key exchange with a SHA-256.

Successfully flash-tuning, reprogramming & otherwise altering the engine control unit to increase power output on the 2020 C8 will be next to impossible.
The anti-hacking encryption written into the electronic control module will block any attempt to "read, write, and/or replace the standard ECU of the C8.
If the ECU detects such an effort, and that programming event fails, the Corvette C8 will enter a "recovery mode" that requires a reboot.

Added to that is GM has assigned each controller a personal security code and becomes embedded into the vehicle system
Only those controllers are allowed to function in that vehicle

The C8 can be reprogrammed but that is only GM software, and only by an entity with the proper encryption keys - meaning a trip on a flatbed to the dealer and a sure fire way to completely void your entire warranty.

The Diffie–Hellman key exchange method allows two parties that have no prior knowledge of each other to jointly establish a shared secret key over an insecure channel. This key can then be used to encrypt subsequent communications using a symmetric key cipher

Ephemeral Diffie-Hellman – This is considered the most secure implementation because it provides perfect forward secrecy. It is generally combined with an algorithm such as DSA or RSA to authenticate one or both of the parties in the connection

Diffie–Hellman key exchange is a method of securely exchanging cryptographic keys over a public channel and was one of the first public-key protocols as conceived by Ralph Merkle and named after Whitfield Diffie and Martin Hellman.

DH is one of the earliest practical examples of public key exchange implemented within the field of cryptography.
Traditionally, secure encrypted communication between two parties required that they first exchange keys by some secure physical means, such as paper key lists transported by a trusted courier.

The Diffie–Hellman key exchange method allows two parties that have no prior knowledge of each other to jointly establish a shared secret key over an insecure channel. This key can then be used to encrypt subsequent communications using a symmetric key cipher.

Diffie–Hellman is used to secure a variety of Internet services. However, research published in October 2015 suggests that the parameters in use for many DH Internet applications at that time are not strong enough to prevent compromise by very well-funded attackers, such as the security services of large governments.

The scheme was published by Whitfield Diffie and Martin Hellman in 1976, but in 1997 it was revealed that James H. Ellis, Clifford *****, and Malcolm J. Williamson of GCHQ, the British signals intelligence agency, had previously shown in 1969 how public-key cryptography could be achieved.

Although Diffie–Hellman key agreement itself is a non-authenticated key-agreement protocol, it provides the basis for a variety of authenticated protocols, and is used to provide forward secrecy in Transport Layer Security's ephemeral modes (referred to as EDH or DHE depending on the cipher suite).

The method was followed shortly afterwards by RSA, an implementation of public-key cryptography using asymmetric algorithms.

 

Not that I'm a believer in the HP gains presented here for this Thorton module, but...

Let's be clear about what is being discussed. They could add a 10-million bit RSA key to the whole shebang and it wouldn't make a bit of difference on whether or not the ECU gets cracked... because when you're busting into a safe, you don't sit at the door and twiddle with the combination for a billion years, you break in through a wall. Same with ECUs. If it's the code you want, you snoop on the buses while it's in operation (particularly during the boot sequence), you look at the format of messages being passed back and forth between modules, etc. Snooping could be as simple as hooking a scope up to a pin, sometimes it involves decapping a chip and wirebonding on en extra few wires, sometimes it involves throwing the chip in a FIB and adding/subtracting connections on the metal layers. You take all of these steps to bypass the 35 million-year core year problem rather than tackling it head on. Once in, reverse engineering the crypto keys being used is child's play, which means talking with the remaining modules immediately follows.

So, cracking the ECU isn't about Diffie-Hellman, Rivest–Shamir–Adleman, or any other cryptosystem, it's about the resources and ingenuity of the people who are actively attacking it... and avoiding the inevitable lawsuit from GM once you've popped the hood

 

Unsubscribing from the thread.....too much anger for such a silly thing.
