The third issue is that the same circuit is used in all different colored cases we opened вЂ“ red, yellow, green, blue вЂ“ it did not matter. The second issue is the claim that it fits SEVERAL different vehicles вЂ“ this is not possible, even for one vehicle, with such a small 3KB program capacity. While we did not get any error codes set by our NitroOBD module, others claim it does set error codes, and if so, this is a major red flag. While some users online claim to have seen small gains in pickup or fuel economy, we believe this is due to either the placebo effect or another vehicle / environmental factors. The circuit appears to monitor the pins from the OBD port and the small microprocessor blinks the lights when activity is detected, giving the appearance of the chipвЂ™s operation. 3KB of memory IS large enough for a light blinker program, however, and we believe this is exactly what it truly is вЂ“ a light blinker in different colored cases. It is clear from our analysis so far that the NitroOBD module does not have the physical capacity to hold real vehicle ECU maps. We did, however, see a neat light show! Nitro OBD lights Analysis We followed the instructions and drove at least 200+ miles to give it the benefit of the doubt, andвЂ¦вЂ¦ nothing. It looks like our suspicions were correct. We connected the Nitro OBD module to our 2012 BMW 530i 3.0L L6 as shown in the instruction sheet and lights began to blink:ДЄnother feature that confirms our suspicions was the fact that the lights blinked in an all too familiar pattern вЂ“ exactly the same as the Nitro OBD scam chip did.

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-ICДЄfter deeper inspection, we see that this chip is aВ 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 reviewsДЇrom 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 вЂ“ 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 вЂXвЂ™ beside them. Internal AnalysisДЄliexpress 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.
