The TJA1050, also decapped, side to side with the Nitro's chip:Īs you can see, the design of the CAN transceiver is very different from the Nitro OBD2's chip. That the designers of this chip could stuff a CAN transceiver inside it?įor reference, here is one of the most common CAN transceivers on the left, Standard microcontroller, with no special embedded device. In this picture, we can see the RAM, Flash and CPU core, but very few other things. But as we areĬurious and like to decap chips, we also wanted to check the inside of the chip.Īfter a quick bath in sulfuric acid at 200☌, here is a picture of the Nitro OBD2 chip: On the single chip of this device so we could not just check its datasheet. Sense since we could not find any CAN transceiver on the board. With this setup, we are able to sniff the CAN bus traffic, while the Nitro OBD2įrom that point on, we can already say that this chip is not communicating on the CAN bus, which makes So we opened the Nitro OBD2 to solder 3 wires on the Ground, CAN_High and CAN_LowĪnd plugged the Raspberry's PiCAN2 interface on these wires. OBD2 port in the car, we decided to connect our monitoring tool inside the Nitro device. Next, we need to record the CAN messages when the Nitro device is plugged in. We have an operational setup with a CAN bus working as expected and some monitoring tools. Just to be sure, we also checked the CAN signals with a PicoScope. The following setup is used to record the CAN messages directly from the OBD2 port: Which enables to read from socket-can interfaces. Messages seen on the OBD port, using a RaspberryPi and a PiCAN2 shield, and If new messages are sent by the Nitro OBD2. Just need to record all CAN messages, before and after plugging it, and check In order to see if the Nitro OBD2 is actually doing something on the CAN bus, we To get various information about the engine, and reset the error codes (DTCs). We chose Guillaume's car, a 2012 diesel Suzuki Swift, because he is used toĬommunicate with it using an ELM327 and Torque on Android. On the CAN bus of a car and check if it sends anything. One easy way to determine if this device actually does something is to plug it Everything had to be packed into a single We began to be very sceptical about this device.
#REVIEWS ON THORTON CHIP TUNING SOFTWARE#
The software part is responsible for all the magic like: The circuit board didn't seem to contain any CAN transceiver, so either there was none,Įither it was directly integrated in the small chip along with its software. Those related to CAN, the others are connected to LEDs.Īt this point, we can already recreate the basic layout of the board: The circuit board shows that the only useful pins connected to the chip are

The connected pins were the onesĬorresponding to the CAN bus, J1850 bus and ISO 9141-2 protocols: Stopped here and be quite disappointing!).

Were at least connected (and, thankfully, they were, or else this article would have Here is what it looks like, and what each pin refers to:įirst, we tried to figure out if the pins corresponding to CANH and CANL Before plugging this thing into a car, we decided to check what was inside.Īfter opening the dongle, we were greeted with the classical OBD2 pinout. and like "akirby" said, "you get what you pay for". It does a little improvement but far from what I was expecting for the price I paid.
#REVIEWS ON THORTON CHIP TUNING DOWNLOAD#
I myself bought a Livernois Motorsports tuner for my '19 (for which Livernois sends you some tunes which you download yourself in it, and then transfer them to your vehicle's computer) and although it's not too bad, I have mixed feelings about it. And last, some more advanced programmers will let you to change the parameters yourself but you better have more knowledge, some basic tuning skills and know what you're doing so you won't do something bad (like going too lean) that could hurt the engine. By comparison, a tuner (depending on which one you have) can have several already made tunes stored in it and you can choose which tune you want to download. You plug the chip in and you have to live with the parameters that are built in it without any possibility to do changes to the program. There are good ones and some others not as good. The main difference between a chip and a tuner is that the chip has a "fixed" program in it.
