Review of each ECU family January 5.1 and January 7.2. Features of each ECU family, comparison and interchangeability. The following blocks are considered: January 7.2 2111-1411020-82 21114-1411020-32 21124-1411020-32 21067-1411020-11 11183-1411020-21 January 5.1 2112-1411020-41 2111-1411020-71 2111-1411020-61 2112-1411020-71 2104-1411020-01 The main difference between January 5.1 and January 7.2 is in the processing of the detonation channel. On 5.1, due to the presence of the HIP9010 processing processor, on 7.2 there is no processor, the channel is software. The January 5.1 ECU detects detonation better than the 7.2. In addition, the January 7.2 can control the starter. The difference between the ECUs of each family, January 5.1 and January 7.2, is in the firmware designed individually for each engine model and the configuration of sensors. For example, in January 5.1.3 there is no detonation sensor and phase sensor, in January 5.1-41 they are present. group in contact http://vk.com/paulxenon video how to make a contract of sale of a car • Video
