Script for mileage correction in BOSCH instrument panels of BRP (Bombardier) equipment manufactured in 2019-2021, made on the Renesas/NEC 70F3554M1 microcontroller.

The script supports reading/writing the microcontroller's DataFlash and has a built-in mileage calculator.

I'll tell you a little about these panels. They are interesting because it is very problematic to disassemble them. The plastic speedometer housing consists of 2 parts glued together. Opening the instrument panel along this seam, we get chips and dents along the seam, and you can also damage the display cable located next to the case seam. Well, no less interesting is the mileage recalculation itself in the dump covered with checksums. Actually, this is why this script was created to make it easier to work with these instrument panels. To work with the script, a small technological hole is cut in the back cover of the case and several wires are soldered to the board. The connection is in the pdf help file. The calculation of the new mileage works ONLY with the instrument panel connected to the programmer.
