SuperOBD Performance Chip Review / Teardown

To begin, if you have not already seen the tests by quarkslab on reverse engineering the Nitro OBD2 performance chip scam, check it out here:

We point you in this direction because this scam has been flooding the internet for a few years now, and has given birth to numerous others with varying colors and logos. We provide our analysis below of the SuperOBD performance chip and show what is inside. To accurately understand the big picture you should first read the above quarkslab article in its entirety. It is proven based on several different articles and tests that the Nitro OBD module is a verified scam.

There are also several youtube videos proving the details of the Nitro-OBD light flasher scam and some of it's variants:

This article involves reverse engineering and analyzing the OBD chip called the "SuperOBD2 Tuning Chip" in order to identify if it functions as advertised or not.

It is advertised like this on the Amazon product page: "Super OBD2 is a Plug&Drive Ready device to function the increasing the performance of engine.Super OBD2 is easy to install. Just plug it into the OBD2 connector of cars. Super OBD2 fits all car from the year of 1996.It works based OBD2 protocols as remaping the Car's computer ECU. After driving 200 km road total, Super OBD2 adjusts itself to the car,according to the drivers' habits and always keeps remaping the ECU to increase the performance of engine. What does Super OBD2 make?According to your driving habits, Super OBD2 makes new map in the car's computer ECU to increase the performance of your car.As you driving much more KM/Mile, it renews the map."

There are a lot of testimonials on the internet about this device being a fake, while other people say that it really works. We wanted to reverse engineer it to check for ourselves. One issue we already see with the product is the claim that it 'fits all car from the year of 1996'. Most legitimate tuning devices must be custom made for one specific vehicle application.

SuperOBD OBDII Chiptuning Box Amazon Product Listing


The price for the SuperOBD2 Tuning Chip on Amazon above was $35.94. However, some digging on the overseas website aliexpress shows the price is much less when purchased directly from the manufacturer in CHINA, $1.97:

Armed with the fact that the well-known Nitro OBD scam chips, like the majority of them, were also made in China, and the fact that the ad above shows "Nitro OBD" in the title, we know the Super OBD Box is related to the Nitro OBD scam chips, but how close are they?


We purchased one of these Super OBD2 OBDII Chiptuning boxes for testing and disassembled the outer plastic case. The inside was identical to the Nitro OBD verified chiptuning scam.

SUPER OBD2 Tuning Box Circuit board we examined, they are identical:

In addition, the original Nitro OBD scam circuit board has three surface mount LEDs present. The Super OBD2 circuit board on the right also has three surface mount LEDs. They both have a diode supposedly for 'circuit protection', as well as a 5V surface mounted voltage regulator.
The final proof is the presence of the PIC16F59 chip, mentioned in many videos proving the Nitro OBD tuning box scam. The PIC16F59 microprocessor is made by the US company Microchip, and has a memory size of only 3KB. This is way too small to contain a vehicle map table as claimed by the manufacturer:

Most vehicle maps are 512KB or larger, depending on the vehicle model and configuration:

While this small memory capacity could not hold vehicle map data, it would hold a simple light flashing routine, which is exactly what the NITRO OBD has been proven to contain. From these facts, we can clearly see that the SUPER OBD2 OBDII Chiptuning Box is nothing more than another NITRO OBD light flasher scam with a round reset button added! The manufacturer even compares the product to it's earlier cousin, the Nitro OBD Tuning box:

To confirm this, we connected the Super OBDII Box to a vehicle and drove for approximately three weeks, doing multiple gas fill-ups and noticed no difference in fuel economy, performance or any other vehicle behaviour.

To confirm further that the programming inside the microprocessor is indeed the same as the verified Nitro OBD scam, we connected both modules to a 12V power supply on the bench and noted the blink intervals of the led lights:

Blink Test - Nitro OBD (Left) Vs SuperOBD (Right)

Blink Test Video:

Both the Nitro OBD tuning scam (Left) and the SUPER OBD2 Tuning Box (Right) blinked in EXACTLY the same interval!
Same board components, same blinking interval, same scam.


From our research as well as testing we can safely conclude that the SUPER OBDII OBD2 Chiptuning Box is nothing more than another Nitro OBD scam. Fun light blinker, crappy tuner.
