i don't have a VEMS-ECU i just bought the VEMSRoundV2 and i like to log both afr and egt values to a storage in my ESP32 driven boardcomputer |

* must be a misunderstanding , since VEMS round v2 does NOT output AIM. It understands AIM stream coming from other source, typicelly v3 RS232 or 2nd RS232 see BroadcastDatastreamAim * I don't have a VEMS-ECU i just bought the VEMSRoundV2 and i like to log both afr and egt values to a storage in my ESP32 driven boardcomputer |
Triggerframe protocol: "Unescape HDLC 7E between frames", 7D 5D => 7D and 7D 5E => 7E check modbus CRC and the bytes are there ("type" is NOT at the beginning, but type is the last byte just before CRC). Sniff some short VemsTune - Round communication to see some valid request response frames: * 0xA0 short request * and 0x20 response (with all runtime and analog data) |
