The datasheet shows this IC has only 8KB of program memory, also too small for genuine vehicle maps STM Datasheet Fuel Pro Max Operation The second circuit board is built around a hidden IC on the back of the PCB: NITRO-OBD-hidden-ICĪfter deeper inspection, we see that this chip is a STM8S003F3, a value line IC manufactured by ST. What can be stored in such a small 3KB sized space then? We have our own suspicion. So, if this is the case, there are no genuine vehicle maps onboard the module. Right away we see a problem here, because if one pulls the datasheet for the PIC16F59 IC, we can see from the manufacturer, Microchip, that this chip has a maximum program memory size of 3KB: PIC16F59 Datasheet car chip reviewsįrom several searches, we verified that ECU maps for a vehicle will be at least 20KB or larger PER MAP! This is way too large for the PIC16F59 IC to contain. The first circuit board is built around a PIC16F59 IC: Nitro-OBD Why make the first one appear to be the best? Answer: Simple – it is the one they are tying to sell you! While they say the first is best, the middle board is actually the original version, and was seen in the earliest NitroOBD modules.
They show a checkmark beside the first one, while the others have an ‘X’ beside them. Internal AnalysisĪliexpress even shows three different versions of circuit boards: Nitro-OBD-PCBs-Aliexpress The instructions claim to have vehicle maps onboard to allow the device to optimize the vehicle performance when connected to the OBD port. NitroOBD2 Chip Tuning Box will recognize your vehicle and your driving habits, after around 200 km/150 miles driving and thus NitroOBD2 Performance Chip Tuning Box will adjust itself to match your car perfectly for more fuel saving. (NitroOBD2 Chip Tuning Box will communicate and establish connection with ECU) 5. After releasing the buttom, just wait for a while about 30-54 sec. Insert the key into the ignition and twist the key to the first stage. Find OBD2 connector(*) in your car and Plug in NitroOBD2 Chip Tuning Box NitroOBD2 Chip Tuning Box for Diesel and Benzine Cars, make your vehicle Lower Fuel and Lower Emission, 1.The product instructions state the following: We will examine the most common Yellow module first: nitro-obd GREEN Case – Fuel Saving for Benzine (Gasoline) EnginesīLUE Case – Fuel Saving for Diesel Engines RED Case – Performance Boost For Diesel Engines YELLOW Case – Performance Boost For Benzine (Gasoline) Engines If you own an LA small-block-powered Mopar car or truck, this invaluable guidance and instruction will allow you to optimize performance and maintain reliability.The OBD tuner modules come in four different colors, and they claim each is for a different type of engine: By 1992, the LA engine platform had evolved into the Magnum 5.2- and 5.9-liter engines and became the new standard of Mopar small-block performance.

The LA was offered in 273-, 318-, 340- and 360-ci inch iterations, and a full range of aftermarket products are offered for these engines. With its compact size, 50-pound weight savings, thin wall casting, and wedge heads, it cranked out a lot of torque and horsepower, so it was formidable competition on the street and track. The LA designates the small-block as "Lightweight A," which was a huge improvement over the previous generation. While these venerable small-blocks have delivered impressive performance in stock trim, both can be easily modified to produce much greater power for almost any application. And the LA engine is also the powerplant for many classic Mopar muscle cars, including the Charger, Barracuda, Challenger, Dart, and others. The Chrysler LA-series and Magnum small-blocks are powerful, efficient, and quick-revving engines that have dutifully powered millions of Chrysler/Dodge/Plymouth cars and trucks from 1964 to 2003. In addition, he provides exquisite details and in-depth buildup instruction for other essential components: blocks, cranks, pistons, rods, ignition systems, intakes, carburetors, and exhaust. Mopar engine expert and author Larry Shepard covers heads, cams, and valvetrain products and modifications that will give you more power. Hit the horsepower goal of your Mopar small-block engine using this guide that identifies the best parts and techniques to extract maximum performance from LA and Magnum powerplants.
