As a rule, the mileage calculation algorithm is secret (closed) information of panel manufacturers, and the algorithms used in the program can sometimes be mistaken for + - 250 km. It may be necessary to make a swap (swap high and low byte). Read and calculated data may differ for several reasons:ġ. Try to record the new value of the run on the new chip, so that in which case you always have the original on hand.īefore changing the run, calculate the current one and compare it with the original content of the chip's firmware. Some chips have a read / write protection, to work with them, programmers are needed to bypass this protection.Īfter you read the contents of the memory, analyze it, if it contains only 00 or FF, it means that the contents were not read correctly.Īfter reading the contents of the memory, be sure to back up this data.
If mileage is recorded on EEPROM, and there are several (identical) ones on the board, then it is necessary to select the one closest to the display or processor.
Here are some tips for using the authors of the program: In order to use the program it is necessary to have a programmer of microcircuits (for example, X-Prog M) The program provides addresses and address values to set the desired mileage. Probably one of the most complete programs for recalculating the mileage of a / m.
