Dash and Data from OBD2 serial

New here and not sure which forum this should be posted on.

Looking for put a digital dash in our 96 s10 used for Champ Car racing, and struck out on trying to get a HAltech ic-7 trying to work because our PCM sends data via serial connection through the OBD2 connector.

Is is possible that the legacy MK3 racecapture, plus a screen would accomplish what we are trying to do and read data via serial and be able to send it to a screen located on the steering column? We were thinking of getting an MK3 anyway to communicate with pit box.

Thanks!

John

You mean a serial connection, like an RS232 connection?

If so, it may be possible if you understand the protocol. RaceCapture/Pro MK3 has an auxiliary RS232 connection that you can access via lua scripting.

We have an example of that communicating with the older RaceTechnology DL1 data loggers via the RS232 serial ports:

This is an advanced topic; you will need to have software developer skills, or find someone who can help you.

Good luck, let us know how it goes!
