Hello,
I am new to RealDash and would sincerely appreciate your technical guidance.
My vehicle is a 2022 Toyota GR86 (ZN8).
I am using a WiCAN OBD C3 adapter and have tested the following two connection configurations:
WiCAN side: REALDASH protocol
RealDash side: REALDASH CAN
WiCAN side: SLCAN
RealDash side: SLCAN
In both configurations, communication appears to be working correctly because I can clearly see live CAN frames in the RealDash CAN Monitor.
Below is a sample of the CAN Monitor log:
1003 54:33.6 ch1 R 0x0040 x| 2E 05 A0 82 00 00 00 C7
1015 54:33.7 ch1 R 0x0040 x| 32 06 A2 82 00 00 00 C8
1017 54:33.7 ch1 R 0x0040 x| 32 07 A2 82 00 00 00 C7
1027 54:33.7 ch1 R 0x0040 x| 33 08 A2 82 00 00 00 C7
1029 54:33.7 ch1 R 0x0040 x| 34 09 A2 82 00 00 00 C7
1040 54:33.7 ch1 R 0x0040 x| 37 0A A4 82 00 00 00 C7
1045 54:33.7 ch1 R 0x0040 x| 39 0B A4 82 00 00 00 C8
1055 54:33.7 ch1 R 0x0040 x| 39 0C A4 82 00 00 00 C7
1058 54:33.7 ch1 R 0x0040 x| 3A 0D A4 82 00 00 00 C7
1068 54:33.7 ch1 R 0x0040 x| 3B 0E A4 82 00 00 00 C7
1071 54:33.7 ch1 R 0x0040 x| 3D 0F A4 82 00 00 00 C8
1083 54:33.8 ch1 R 0x0040 x| 2D 00 A4 82 00 00 00 C7
1086 54:33.8 ch1 R 0x0040 x| 2E 01 A4 82 00 00 00 C7
1095 54:33.8 ch1 R 0x0040 x| 2F 02 A4 82 00 00 00 C7
1097 54:33.8 ch1 R 0x0040 x| 2E 03 A2 82 00 00 00 C7
As shown above, CAN ID 0x0040 is clearly being received, and the first two bytes are continuously changing.
However, none of the dashboard gauges respond.
I am currently using the following XML configuration:
<?xml version="1.0" encoding="UTF-8"?>Based on my understanding:
The CAN ID is 0x40 (11-bit standard ID)
The data appears to be little-endian
Engine RPM should be stored in bytes 0–1 (16-bit little endian)
Despite this, although the CAN Monitor shows live data, the dashboard gauge does not move.
Could this issue be related to:
Channel naming requirements in RealDash?
A difference between 11-bit and 29-bit CAN ID handling?
A difference in how CAN Monitor frames are processed versus how dashboard values are parsed?
Or an error in my XML definition?
I would greatly appreciate any clarification or advice.
Thank you very much for your time and support.
