CANBUS Gear display on Dash 4

Postby Bmsport » Mon Jan 04, 2021 5:00 pm

I have an original/early Dash 4 Pro and the last of the Video 4 system with GPS and a serial connector to read the CAN from my MBE ECU. Can I display the current gear from the CAN on my Dash 4. I can only find a possible calculated gear, for this I need all the gear ratios and tyre circumfurences or run an analog signal, but no option for CAN?

Hi - Which model of MBE ECU are you using the Race Technology equipment with?

Thanks

Its an MBE 9A9ECU which uses the same CAN system as the 9A4 and 9A8.

Thanks for the confirmation, we have not connected to a 9A9 yet but if it uses the same CAN protocol as the 9A4 & 9A8 ECUs it should communicate with our products. Unfortunately gear position is not listed as available from CAN - https://www.race-technology.com/wiki/in ... dMBE992CAN

However you will be able to calculate the current gear, based on the RPM and speed signal that the dash is receiving. Enter the gear ratios, final drive and rolling circumference of the wheel.

Thank you for your reply, I can get a gear output from MBE on the CAN bus, but on my Video 4 and my Dash 4 Pro the gear indicator only allows for a serial input from the gear position sensor or from the gear ratio, diff ratio, speed calculation. No option for CAN?
