CAN Bus data convert to other CANBus data

I have two modules (old and new). OLD one (engine ECU) send specyfic canbus data, but NEW one module (dashboard) expect different format CanBus data to display data from ECU.
I need something like canbus converter-bridge to convert old data (ID and message) to new ID and message.
I looking for freelancer, who have hardware for test (simple arduino's canbus shield + uno enough) and UNDERSTAND this job.
To convert 6 IDs with data to other 6 IDs with data.
I put similar job few days ago and wait for freelancer's response. I would like run two similar projects together, so I looking other freelancers to new job.
Before create milestone I expect "proof of concept" sample data conversion to test under canbus sender-reader (sketch to any platform or hex).

I have all nececery data explanation for each ID, and message sample.

EXAMPLE
FRAME MS_312h (0x00000312) Sample data: 08 1F 08 1E 0A 90 08 20
