Displaying Gear from ECU

Postby wil_h » Thu May 05, 2016 9:04 am

I'm trying to display the gear on mt DASH4PRO from my Specialist components Tornado ECU.

I can see that there is a 'Gear (current gear)' in the standard variables, this is set up from the gear menu, using speed and rpm. I have set this up, but it doesn't work because there is no speed input from the ECU. To be clear the ECU has a wheel speed input, but it is clearly not getting to the dash.

The information here https://www.race-technology.com/wiki/in ... AndTyphoon would suggest that the gear input is VAR_1024, but this doesn't work either. Again, to be clear, the ECU uses wheel speed and rpm to calculate the gear, and this all works.

I've spoken to Specialist components and they have told me that the gear CAN output is ID 0x306 byte 0, can this output be configured to display on my dash?

Thanks

are you sending a CAN stream or serial stream to the Dash 4?
If CAN, then yes, no issues.
If serial, you will need to feed a DL1 with the info, buy a CAN license (which I assume you have, if you are getting other channels from the ECU), and then setup gear channel in the CAN config and in the variable config, and then add it to the Dash 4 layout.

Alternatively, you can have a DL1 determine gear by looking at GPS speed and rpm, and you setup the gearbox ratios in the vehicle config file with the Analysis software.

Yeah, sounds simple. Its a CAN stream from the ECU. other channels like oil pressure, water temp, rpm etc work straight away (i.e. right click on display, select input in properties (VAR channel).

But what is the CAN channel for the gear? It's not VAR_1024 as shown in the link, so which VAR channel is it? I put 20 channels on a page and configured them to all the 20 standard channels, but none came up with a gear (I was grabbing at straws!).

When you say set up a CAN channel, where is that configured? all I've done with the others is pick the VAR channel.

Try to send the gear channel info to one of the "aux" variables (ignore the R-T label for that channel).

Already tried that with both VAR channels mentioned, doesn't help.
