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.
