DASH2Pro, 4.0.57.RMG w. CAN option
Megasquirt 2 PnP, x3.4.4

Followed instructions: ... NInterface
Although the screens are slightly different now (see attached).

Can(1) wires connected directly to ECU, CANH to CANH and CANL to CANL

No bueno, Dash is not seeing any data. No RPM. I put the TPS, coolant, and Battery voltage on the first LCD, all showing zero with no changes.

Hello - Looks like a possible configuration issue, could you please send your DASH2 PRO configuration file to me on the following address and I'll take a look: daniel AT race - technology dot com

Thank you, Daniel. That was emailed to you tonight.

As noted in the email I simply started with a new default dash config file and added the ECU from the drop-down. However, I did have a conflict selecting the cooolant temp from the options list, as it complained that Analog 1 was already in use. Despite using the default config file, it did indeed have analog 1-4 configured to be used already, so I de-selected each of those.

Thinking I may have overriden the default config somehow, I deleted the CMG file from my hard drive, verified I could not select it, then did a "repair" on the v10 software install. The resultant CMG was the same.

I look forward to your analysis.

Resolved, and it was my error. In checking my wiring for a third time, I finally recognized that I had swapped within my Deutsch connector off the DASH the white CAN1H wire and the white Analog input 3 wire. Swapped them, used the CMG that Dan provided via email (which I think is better than the default ECU config) and all works fine now. "CAN" showing on the screen and I'm getting (at least) coolant, TPS, and RPM.
