Data Communications Link (DCL) - CART/UART
Posted: 2023 Jan 28, 22:12
I have 100% decompiled the DCL - CART/UART protocol data stream for transmitting and receiving.
Using plain Java, a MAX485 chip, can now communicate with the EEC's that have the 81C62 or 81C65 CART chip, on the D+ and D- test connector.
The C3P2 lightings have mode 0x05 which is for 'Alternate Calibration'. Has any one had success with that?
I am really interested in the following modes:
- 0x43: DCL_DM_ProgramDataDownload
- 0x45: DCL_DM_ProgramExecution
- 0x46: DCL_DM_A-D_SensorValueSubstitution
Has any one had success with this?
From what I understand, is that using A-D_SensorValueSubstitution, this is kept in KAM, and should be able to change any PID value.
I'll be posting my source code, and schematic of the MAX485 once I have more testing complete.
